Two-legged robots are walking, running, jumping and performing human tasks. And like us, robots fall down and often need humans to help.
But self-righting isn’t just a problem for bipedal robots. It’s also an issue for robots that are track or wheel driven. Such robots are used by the military for explosive ordnance disposal and sending a person out to right the robot, in the presence of unexploded ordnance is less than ideal. Wheeled robots are also used for vacuuming floors and while the danger involved in righting one that has fallen down the stairs is less, it still presents a problem.
Army researchers are addressing this issue with a software solution that adds control of articulating joints to the robot offering upwards of eight degrees of freedom to figure out how to right itself. The software evaluates the initial state and works out a series of movements resulting in it getting back on its treads. The sequence of actions is arrived at after assessment of the costs of all other possible actions and articulation routes resulting in a righted position.
- Methodology allows robots to autonomously determine how to right themselves
- Provides designers with a tool to assess whether their robots are able to self-right, and to determine the qualities that make robots more capable to self-righting
- Businesses can acquire the software by licensing US patent 8,977,485
- License fees are negotiable
- Potential for collaboration with Army researchers
- TechLink provides licensing assistance to industry at no charge
