Mars robotic exploration is at the heart of the latest international space missions. Leonardo is involved in the study of cutting edge robotic systems which can contribute to the discovery of the Red Planet’s secrets.

‘Mars Sample Return’ mission

For the NASA ‘Mars Sample Return’ campaign, in collaboration with the European Space Agency (ESA), Leonardo has been awarded a contract with Airbus for the advanced study phase (Advanced B2) of the ESA Sample Fetch Rover’s (SFR) robotic arm and has received financing from ESA to pursue the study of the Sample Transfer Arm (STA) for the NASA lander.

Leonardo is committed to design the respective robotic systems for the acquisition of the samples

Leonardo, also thanks to the important contribution of the Italian Space Agency, is therefore involved in the study of two crucial elements for the 2026 mission of the Mars Sample Return campaign: the arm of the rover and that of the lander. For both, Leonardo is committed to design the respective robotic systems for the acquisition and manipulation of the samples.

SFR industrial consortium

The Sample Fetch Rover (SFR) industrial consortium is led by Airbus UK. The design of the SFR robotic arm, after an early phase of concept study and testing, is now entering into an advanced phase with the development of the first robotic arm prototype (breadboard) to show the high capabilities of the system.

The arm is extendable up to about 110 cm and its control system features 6 degrees of freedom and is equipped with a gripper or end effector at its tip.

Sample Transfer Arm for NASA lander

NASA lander’s Sample Transfer Arm (STA) is a more complex arm, with 7 degrees of freedom that exceeds 200 cm of extension, and it is now beginning the development phase of the breadboard. Leonardo is leading the international industrial consortium in charge of the design of the control electronics, of the software and of the vision system.

The design of both SFR and STA robotic arms is based on the experience gained in the development of the Leonardo DELIAN and DEXARM models, which are still considered standards in the European space market. In addition, the Company has a strong knowledge of the space drilling sector, having developed drills for missions such as Rosetta, ExoMars and Luna-27.

Thales Alenia Space

For the MSR campaign, Leonardo will also contribute to the Earth Return Orbiter (ERO) through Thales Alenia Space (joint venture between Thales 67% and Leonardo 33%), which will be responsible for supplying the communication system allowing data transmission between Earth, ERO and Mars, designing the crucial Orbit Insertion Module, managing the Assembly Integration and Test (AIT) phase for the Proto-Flight model of the ERO spacecraft.

Mars Sample Return (MSR)

The joint ESA/NASA MSR campaign includes three missions that will be launched starting from 2020

The joint ESA/NASA MSR campaign includes three missions that will be launched starting from 2020. These missions will work together to reach the ambitious goal of bringing back to Earth some samples of Mars soil by 2031.

The first NASA mission ‘Mars2020’, launched in July, will see the rover - Perseverance drill down the soil and collect some samples of the Martian ground. Perseverance will seal the rock and soil samples in suitable tubes and will release them in strategic positions waiting to be collected by the following mission.

Sample Retrieval Lander mission

With departure planned in 2026, the ‘Sample Retrieval Lander’ is the second mission of MSR. This mission consists in three elements: the NASA lander, the ESA Sample Fetch Rover, and the Mars Ascent Vehicle (MAV).

Leonardo is involved in the study of the arms for the NASA lander and the ESA rover that will have different features and tasks. The rover, through the robotic arm, will search and collect the tubes with the samples and will take them to the NASA lander. Then, the NASA lander with its ESA arm will move the samples to the MAV that will launch them with a special capsule into the Martian orbit.

Earth Return Orbiter (ERO) mission

Finally, the third mission, the ‘Earth Return Orbiter’ (ERO), will be scheduled in relation to its task of collecting the capsule in orbit and bringing them on Earth. Leonardo, through Thales Alenia Space, will be involved with the furniture of crucial elements of orbiter. Landing is planned in Utah (USA).

Remote Monitoring technology: Tackling South Africa’s cable theft problem
Remote Monitoring technology: Tackling South Africa’s cable theft problem

For decades, cable theft has caused disruption to infrastructure across South Africa, and an issue that permeates the whole supply chain. Here, Ian Loudon, international sales and marketing manager at remote monitoring specialist Omniflex, explains how new cable-alarm technology is making life difficult for criminals and giving hope to businesses. In November 2020, Nasdaq reported that, “When South Africa shut large parts of its economy and transport network during its COVID-19 lockdown, organised, sometimes armed, gangs moved into its crumbling stations to steal the valuable copper from the lines. Now, more than two months after that lockdown ended, the commuter rail system, relied on by millions of commuters, is barely operational.” Private security firm Despite this most recent incident, cable theft is not a new phenomenon to sweep South Africa Despite this most recent incident, cable theft is not a new phenomenon to sweep South Africa. In 2001, SABC TV broadcast a story following two members of a private security firm working for Telkom, a major telecoms provider. In the segment, the two guards, working in Amanzimtoti on the south coast of KwaZulu-Natal, head out to investigate a nearby alarm that has been triggered. They reach a telecoms cabinet and discover that it has been compromised, with the copper cable cut and telephone handsets strewn across the ground. In the dark, they continue to search the area when one of the guards discovers the problem: 500 metres of copper wire has been ripped out. In their haste, the thieves have dropped their loot and fled. Widespread cable theft Had they managed to get away, they would have melted the cable to remove the plastic insulation and sold the copper to a local scrap dealer for around 900 Rand, about $50 US dollars. For the company whose infrastructure has been compromised, it may cost ten times that amount to replace and repair the critical infrastructure. The disappointing takeaway from this story is that two decades on from this incident the country still faces widespread cable theft, whether it’s copper cables from mines, pipelines, railways, telecoms or electrical utilities. In fact, the South African Chamber of Commerce and Industry estimates that cable theft costs the economy between R5–7 billion a year. The answer to the problem must go further than the existing measures used by companies. Detect power failure Most businesses already invest in CCTV, fences, barriers and even patrol guards, but this is not enough. Take the mining sector, for example. These sites can be vast, spanning dozens of kilometres - it’s simply not cost effective to install enough fences or employ enough guards or camera operators. As monitoring technology gets better, the company has seen site managers increasingly use cable alarms in recent years that detect when a power failure occurs. The idea is that, if one can detect a power failure, they can detect whether the cable has been cut The idea is that, if one can detect a power failure, they can detect whether the cable has been cut. The problem is though: how does one distinguish the difference between a situation where a cable has been cut intentionally and a genuine power outage? Power outages in South Africa are an ongoing problem, with the country contending with an energy deficit since late 2005, leading to around 6,000 MW of power cuts in 2019. Remote terminal units Eskom Holdings SOC Ltd., the company that generates around 95 per cent of South Africa’s power has already warned of further blackouts as the company works to carry out repairs to its power plants. According to a statement on the company’s website, “Eskom spends in the region of R2 billion a year replacing stolen copper cables." The result is that criminals take advantage of the gaps in power to steal cable, timing their robberies to coincide with the published load shedding schedules. The basic alarms used to detect power outage won’t recognise the theft because they register a false-positive during a power cut. By the time the power comes back on, the deed has been done and the criminals have gotten away with the cable. The good news is that recent breakthroughs in cable monitoring technology are helping tackle just this problem. New alarms on the market now combine sophisticated GSM-based monitoring systems that use battery powered remote terminal units. Legitimate supply chain Unlike the basic alarms that look for the presence or absence of power, these new systems monitor whether the cable circuit is in an open or closed state. In the event of a power outage, the unit continues to run on battery power and can detect if a cable has been cut, sending a priority SMS alert to the site manager immediately, giving them a fighting chance to prevent a robbery in progress. Beyond the opportunistic theft carried out by petty criminals, the theft of copper cables forms a wider problem Beyond the opportunistic theft carried out by petty criminals, the theft of copper cables forms a wider problem across the supply chain in South Africa. In recent years, the combination of unscrupulous scrap dealers, the alleged involvement of large scrap processing companies and lax penalties meant that much of the stolen copper ended up back in the legitimate supply chain. However, recent changes in the law have sought to take a tougher stance on copper theft. Alarm monitoring technology According to the Western Cape Government, “The Criminal Matters Amendment Act, regulates bail and imposes minimum offences for essential infrastructure-related offences." The act, which came into effect in 2018, recommends sentencing for cable theft, with the minimum sentence for first-time offenders being three years and for those who are involved in instigating or causing damage to infrastructure, the maximum sentence is thirty years. It seems to be working too. In January 2021, the South African reported that a Johannesburg man was sentenced to eight years behind bars for cable theft in Turffontein. While the longer-term outlook is a positive one for industry, the best advice for businesses seeking to alleviate the problem of cable theft in the immediate future is to invest in the latest cable-theft alarm monitoring technology to tackle the problem and make life difficult for criminals.

Maximising supermarket safety with real-time surveillance solutions
Maximising supermarket safety with real-time surveillance solutions

Supermarket employees have been the hidden key workers of the past year, keeping shelves stocked and queues under control as panic buying gripped the nation. As a result of being expected to enforce face covering and social distancing regulations, they also been asked to act as de-facto security guards alongside their existing duties. This is problematic as many employees have never had to deal with this kind of responsibility before, let alone received any conflict de-escalation training. In order to maintain the safety and security of their staff retailers must take additional steps to uphold their duty of care, with the NPCC recently specifying that it is the responsibility of retailers ‘to manage entry to their stores and compliance with the law while customers are inside’. Supermarkets in particular need to be aware of this requirement, as the big four recently announced that their employees would now be challenging customers shopping in groups and those not wearing masks. Verbal abuse from the public Crime against retail employees has already been a major issue over the course of the pandemic, confirmed by research from the Union of Shop, Distributive and Allied Workers that found 90% of retail staff in the UK experienced verbal abuse last year. The Co-op has recently been vocal about the effects of the pandemic and lockdown-related frustrations on its employees.90% of retail staff in the UK experienced verbal abuse last year The supermarket reported a 140% increase in crime within its stores over the past year, with many of the 200,000 cases related to verbal and physical abuse experienced by employees. Jo Whitfield, Co-op Food chief executive, confirmed that the number of issues has already increased drastically as a result of staff enforcing COVID-secure guidelines. So, what steps must retailers take to ensure their duty of care remains intact as employees take on new enforcement responsibilities? Introducing real-time surveillance technology to support security guards and shop floor employees alike is vital. Bolstering front line defences Security guards posted at supermarket entrances are the first line of defence against shoppers determined to break the rules. However, they are now being pulled in multiple directions with queues to monitor and occupancy to manually keep track of, along with the usual security alarms to respond to. With one person usually posted at the entrance at any one time it’s simply impossible to have eyes everywhere, which is where automated video surveillance comes in. COVID-specific technologies, such as mask detection and occupancy management systems, are now the golden bullet to retail safety and security.Mask detection and occupancy management surveillance tools can automatically alert a shopper Mask detection and occupancy management surveillance tools can automatically alert a shopper whether or not they are allowed to enter the store on their approach to the door. The system surveys the person and a screen will automatically display different instructions depending on the situation: whether they must put a mask on before they enter, wait until capacity is low enough to enable social distancing or, if the previous criteria are fulfilled, that they are free to enter. COVID-secure safety This stand-off technology minimises the need for contact between security personnel and shoppers, allowing security guards to complete their usual duties, safe in the knowledge that the store is being managed in a COVID-secure way. With a hands-off approach enabled by surveillance technology, the potential for tense confrontation is greatly diminished as customers will usually comply to the reminder shown to them and put on a mask or wait without further prompting from staff. With security personnel able to better focus their attention on the stubborn rule-breakers,It is crucial that retailers choose a solution embedded in real-time connectivity this responsibility will no longer land with staff on the shop floor who are often ill-equipped to deal with this situation. It is crucial that retailers choose a solution embedded in real-time connectivity that will allow all store entrances to be screened simultaneously. Nobody can be in multiple places at once, but this connectivity allows alerts to be streamed instantly to any connected device that can be monitored by just one employee, meaning they can review the alerts that require their attention without needing to be physically present or re-tasked away from their day-to-day duties. Instant reassurance with body worn tech As a customer-facing role, there can be no guarantee that shop workers will never experience a potentially violent confrontation with a customer, which is where the presence of live streaming body worn cameras can help. While they may not always be trained to de-escalate a risky situation, being able to discreetly call for assistance can provide the reassurance employees need to feel safe and supported at all times. If an employee asks a customer to put a mask on while they’re in the store or step back from another shopper and the situation turns abusive – verbally or physically – a live streaming-enabled body worn camera can be triggered to stream a live audio and video feed back to a central control room manned by trained security personnel.A live streaming-enabled body worn camera can be triggered This real-time footage gives security staff exceptional situational awareness, allowing them to fully assess the situation and decide on the best course of action to support the employee in distress, whether that is going to the scene to diffuse the situation or contacting the police in more serious circumstances. Bolstering front line security This goes one step further than record-only body worn cameras, the capabilities of which these next generation devices match and exceed. Record-only cameras are well-suited to provide after-the-fact evidence if a customer interaction turns sour, but they do little to provide reassurance to out of depth employees in the moment. The duty of care grocery retailers must provide to their employees has never been more important, with staff taking on new mask and social distancing enforcement responsibilities and managing interactions with frustrated customers. Bolstering front line security and giving staff extra reassurances with the introduction of real-time video surveillance technology is a crucial step for retailers striving to keep employees and shoppers safe during these challenging times.
