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.
Hazbot: you could replace the wheels of the counterweight by a servo for rotation of the wrist with a carbon fiber rod (light and strong) to transmit the rotation of the wrist, so you would have a similar weight in the counterweight with more movement. It's an idea, I have mounted the servo gripper opening in the shoulder so that acts of contapeso.:)
@R2D2 - that's a great idea.
R2D2 - That's a fantastic idea and I will use it... You guys have so much great ideas and info - Now I'm still hanging for that Tank base for his treads to get around... Should arrive soon. Thanks again..
Glad to be helpful, here bearing supports pede find very very cheap for carbon or aluminum rod, 5mm thick, Greetings.
