We have received some of the parts we need for the Exo Arm build. A BIG thank you to Schaeffler Group USA, Inc for donating the parts and Motion Industries, Inc for facilitating the ordering and parts. Jesse and Bill have been great to work with in getting the right parts ordered. We appreciate their time and consideration.

The linear rail which will be the "backbone" for the Exo Arm looks like it will work well for supporting the rest of the assembly. When we looked at the bearing rail block that rides on it on the rail it was incredibly smooth motion. You can tell it was well designed and built. We originally were going to take a smaller piece of metal square tubing and put it inside a larger tube, drill holes and allow this to be our adjustment for shoulder height. The linear rail will provide a much smoother movement than we anticipated.

Concerns are that the single linear aligning block and bearing will not be enough to support the arm structure. The block will hold about 320 lbs of dynamic force which should be enough to support the load, however, the blocks are small and we need more surface area to attach a plate for the shoulder joint. We are therefore going to double the block.
