But it only walks downhill.

- khafra 15y agoThanks for taking the thermodynamics-defiance out of the robot and replacing it with kinetic energy over time.
- artmageddon 15y agoTrue, but doesn't this mean that biped robots wouldn't be required to expend energy when walking downhill? Depending on the application, it can greatly increase the time that a robot can be in use.
- pavel_lishin 15y agoIt might be pretty difficult to build a robot that can both walk passively downhill, and walk actively uphill. Can that thing walk downhill over an uneven terrain?
- artmageddon 15y agoBigDog was able to go both uphill and downhill, as well as even be kicked from the side while maintaining balance. Good point regarding being passive, I figured that somehow the robot would figure out the slope and provide extra power when the terrain was uneven or if it would be unable to maintain a given speed passively.
- pavel_lishin 15y agoBigDog didn't walk downhill passively, did it?
- artmageddon 15y agoNo, it didn't. Sorry if that's how it came across - I was just supposing that this concept could be use to extend the life of a robot such as BigDog or others by controlling how passive it was in response to downhill slopes.
- sliverstorm 15y agoWe could go downhill with (almost) no power too, if only we could coast-run fast enough (and could handle the shock in your leg when your stride becomes so long you fall several feet with each step)
- nitrogen 15y agoand could handle the shock in your leg when your stride becomes so long you fall several feet with each step This is possible when running down a steep sand incline. Very fun.
- compumike 15y agoSee "Toddler learning to walk" at http://groups.csail.mit.edu/locomotion/videos.html http://groups.csail.mit.edu/locomotion/videos.html (2004). At first, the robot walks passively down an inclined treadmill. But it quickly learns how to efficiently add just a little bit of power from its motors at the right time each stride, such that it soon walks on level ground and adapts to different surraces.
