Robot Learning to Reach

This video shows robot Dexter through exploration learns to assemble the appropriate sequence of actions that leads to the rewarding tactile sensation. This process is analogus to the "motor babbling" stage during infant development.

what people dont know is that the ball was hot and the poor robot was burning its hand! XD

Cool hehe

At least she didn't smudge her lipstick!

@fashanu1000 they have been trying that for 40 years...and getting no where.

When will there be a pleasure model available to buy?

nasa and 15year old nerds are at the same level of building robots i haven;t seen anything different in robotics not from japan or a kid building his own personal robots its all algorithms,they should make an A.I that adapts to its surroundings though learning

@bigpauly2000 The simulator doesn't have to be perfectly (or even extremely) accurate - I saw a paper a while back where Q-learning was used first in a simplified model, then in a real environment, to jump start the learning process (which is usually very slow with Q-learning for complicated state spaces/tasks).

There was an analogy that even a totally novice driver rapidly learns that turning the wheel left makes the car turn left, even if the degree/speed of the turn are not known to them.

it's like "ooooo, poke hehehehehehe, Poke! hehehehehe, Poke!"

@StormWolf01 That works for some tasks, however for many tasks writing an accurate simulator would be harder than actually learning in the real world. I think you are right that in this particular task the learning could be done in simulation.

[StormWolf01]

Isn't it possible to evolve the software in a simulated 3D environment? And once the software is evolved right, input it back in the robot?

I am saying that because the software can evolve much faster in a simulated environment than in the real world. Of course i guess you would have to model the robot in the right proportions and all, but i don't see why it would be a problem.

With that, you could use distributed computing to evolve the software even faster.

I think it looks awesome!

It looks like the arms our working.
