U.S. Army Research Laboratory (ARL) and Johns Hopkins University (JHU) Applied Physics Laboratory (APL) researchers have developed software to ensure that if a military robot falls to the ground, it can right itself.

The team applied software to the Advanced Explosive Ordnance Disposal Robotic System (AEODRS), a new line of Explosive Ordnance Disposal robots with a modular open systems framework.

JHU/APL researcher Galen Mullins said the software relies on an adaptive sampling algorithm that seeks transitions.

"We were looking for states where the robot could transition from a stable configuration to an unstable one, thus causing the robot to tip over,” said Mullins. “My techniques were able to effectively predict where those transitions might be so that we could search the space efficiently."

The team found the software permitted AEODRS robots to right themselves on level ground, irrespective of their initial state.
