Robot Arm Designs

Anyone interested in creating a team to brain storm ideas and designs for robot arms for large or small robots. Perhaps collectively we could come up with a universal design that many of us could use. We each could provide input, drawings and/or services.

Loki looks pre-scripted. The video skips a lot per take to get it right I think:)

I also got that impression...but was hoping....anyway...

DJ any updates on Synthia?

There I go again... getting off topic of my own thread :P

Back to topic, I am working on my arms for B9 and the design may be good for small bots. I'll post images/videos after I get the kinks worked out.

Thanks for sewing the thread back into the topic :D If I don't get to many more"honey do" lists when I get home, I'll do my best to take pictures of my shoulder setup for Magnus. The claws I think I can create OK. The elbow is the problem.

Here are some pictures of the shoulder drive mechanism and arm socket for Magnus. Please pardon the dust. Paint job is still far in the future ;)

Arm Socket that I installed into the clothes dryer drum.

Shoulder Drive Mechanism: Support structure is two 1/8" thick steel plates and a 2" x 2" steel tube pedestal. Chain drive with two pillow block bearings. 1" hollow steel tube passes through the bearings. #25 chain and associated sprockets. 12V 400 in.lb. torque motor.

The actual arm is a separate entity. It will mount to this disk and tube. This tube was turned down on a lathe so that it slides smoothly into the 1" tube and serves as a wire-way to the arm as well. It will have a pin (not shown in picture) that will lock it into the shoulder disc so that the arm will rotate with the shoulder. That way when I need to remove the torso all I have to do is unplug the cable harness, pull a lock pin and off pops his arm.
