Operating as a team, an autonomous vehicle with an unmanned aerial vehicle () flying overhead as surveillance could go deep into complex and unfamiliar terrains such as dense forests to deliver supplies to the battlefield.
Such air-to-ground “teaming”, where the can take off from and land vertically on the unmanned ground vehicle, is a key project being developed by Singapore’s Defence Ministry’s research-and-development arm DSO.
According to todayonline.com, the vehicles will also be able to navigate without the use of the Global Positioning System (GPS), a rarity among unmanned systems globally.
The V35 next-generation can be mounted atop the unmanned ground vehicle, allowing it to travel “more than three times” further, since it can be transported out into the field to be launched.
Hikaru Fujishima, a program manager in DSO’s information division, said: “The aircraft will now have an extended range compared with launching (it) right from the beginning (from a runway).” Typically, s of similar size would need a 500m-long runway to take off. This next-generation eliminates the need for one.
Jonathan Yong, a senior research engineer in DSO’s guided systems division, said: “Not only can (the ) be launched from a vehicle, it can be launched from a small area of clearing in the forest … so it makes it a lot more attractive for our forces.”
The can clock “more than 10 hours” of continuous flight with the vertical take-off and landing capabilities.
The new system also cuts the reliance on manpower, requiring just two persons to assemble and deploy. Otherwise, it is typically a six-man team, including operators and ground crew, who have to roll the aircraft out to the runway, for example.
Both the aerial and ground vehicles navigate without GPS, by banking on navigation techniques such as light detection and ranging, the unmanned ground vehicle’s vision sensors, and the ’s satellite maps. This means they can navigate in both forests and urban environments, Fujishima said.
A possible scenario may see both vehicles being sent into battlefield to deliver supplies, with the scouting the surroundings so that they advance safely.
Singapore’s Defence Minister Ng Eng Hen pointed out that the challenges facing the SAF would require more effective and intelligent use of technology, especially when there are manpower constraints.The DSO is focusing on robotics, autonomous systems and artificial intelligence — if successful, these initiatives would help the SAF to meet the challenges it confronts, he added.
Inaugurating the new DSO complex, Defence Minister Ng Eng Hen noted that the nature of security threats today, such as the presence of suicide-bombers and lone-wolf attacks, were unheard of more than a decade ago. The work of the employees in the DSO Complex “will determine whether we have the wherewithal to meet this threat”, he said.
