Our robot "Bob" is becoming demanding. Now he wants to not just move his arms up and down but be able to grab things. We've been experimenting and searching the internet for ideas but keep getting the large clunky, sit on desk, rotational arm clones. It appears in this area innovation has almost dried up. If anyone has anything that can be not just be an arm on a desk but part of a robot - please let us know. Simple is best. I'm trying things with just 2 servos and parts of plastic bottles and household junk but nothing worth showing just yet.
