This is my third bot. I used a few ideas from my other two and added the lifting arm and grippers. I am hoping to be able to search for, lift and carry a beer can, full would be usable but I doubt if the power is there with the present motor.

Mechanically the bot is complete. I have enough code to test all the functions.
