My own walker robot! Made with Arduino Uno.
Still need to work on the legs to give it a better grip. And cut down the weight by removing the breadboard and a lighter Arduino nano.
I have added some grip to the legs with some elastic rubberbands, but not much improvement. My Arduino Nano came in the mail so I have added that instead of the Uno board. This version also uses a blackberry phone battery that I mentioned in the previous post, it seems to work well.
Added more grip with the rubber fingers that are used in offices to count money/paper etc.
