I believe a vex cable system would work well. For instance in some advanced robotic arms cables are used to transfer power to the joints or grippers of the arm when the motors are actually in the body. Ideally the cable could be cut and cinched to a drum that it would be coiled around. That drum, the cable, maybe some Teflon guides, and a few pulleys for in the arm would allow anyone to build an robotic arm with joints and grippers and keep the motors out of the arm where they look protruding and hurt the center of gravity. The cables linking the motors in the body of the robot with the joints in the arm would help streamline the arm making them look and work better. It could also be used as a winch or crane system. Just an idea wanted some thoughts on it.
I know i could use the chain and sprocket kit but you cant weave multiple chains inside of a c channel and they would rub against things and each other not making a smooth ride. I know i could probably make this kit for myself but i like the more professional look to the kits. This takes it a step beyond the chain and sprocket kit in transferring power. Thoughts on this idea are appreciated.
