A lifter and carrier.. It's not pretty or very useful but it was fun to built and fun to play with for around ten minutes. It was built six month before the video was made and at that time it was able to move with the 1kg bag but it seems the assembly somehow sat itself. Design fault i guess

They are fast, very cool :)

Thanks for finding a positive thing to say

Very nice robots.

I watched the whole video, it was really fun to watch them. Reminds me of our cats playing around. Did you use a proportional controller for the one with the claw?

Looks fun Liked the bit of the video where the can rolled away

Nice robots!

I find this video simply wonderful! Very funny, and the robots are nice and fast!
