Has anyone built a shoulder, a

Question

Has anyone built a shoulder, arm and hand other than the Imoov design. I am looking for something with more strength. I want to get away from the cable design. I have linear motors and stepper motors and want to use a more direct mechanical design. Any ideas?

Hello Patrick. I really want a much stronger design. It needs to be like a Imoov sized arm. I want to lift some reasonable weight. Thanks for the reply. Stay well.

Andy Roid · Answer

It will need to lift 3 to 4 kg. I have a linear motor which can drive it. I am looking for the mechanical ideas. Remember Tony?  He was building robots and selling them. He use to do a lot of design work. I may have to look at some of his old post. Some of the joint designs were a good concept.

Hello Patrick. I was really impressed with the monster servo setup. LOTS of torque. like what I need. I will start working on the elbow joint design considering the layout of the monster servo as shown in the video. Thanks for searching out the info for me. I will be jumping back to a base I'm building using hoverboard motors like Will is working on. Once I get my parts and he begins testing i will too. Thanks again for your help. The arm is going to be a fun project.
