ACM-R4.2 is a snake-like robot used for inspection in narrow and uneven places. It could be used for search & rescue missions inside debris of destroyed structures, inspection of ducts and confined spaces, and more.
One unusual application took place in Tasmania in 2016: ACM-R4.2 was drafted to go underground inside a wombat burrow and record some videos of the new friends.
The burrow system explored was actually more complex than expected, but the articulated body of ACM-R4.2 proved ideal to navigate the tunnels and chambers. In the end, ACM-R4.2 found a few wombats at home, but some were too shy and only showed their tails to the robot (actually, this is a defensive posture, since the tail of the wombat is very hard).
