    I chose to pre-drill the holes on the plate and angle iron, before I welded the brace together, because it was easier to hold the parts for machining. I was a little concerned that the holes might not line up, once I put the robot in the zero position, but the holes lined up fine.

    Robot Brace

    While measuring the deflection of the waist axis of a robot we needed a brace to keep the brake from the shoulder axis from back driving, which would cause the arm to drop, when we hung weights on the elbow of the robot. I had to replace the bearings that guided the blade on my swivel mast saw. The...

    Robot Weight Bracket

    We needed to measure the stiffness of the waist axis of a robot. We have a bunch of 50 lb bar bell weights. I designed and fabricated a fixture that we can hang from the elbow of the robot to safely add the weights one by one while we measure the deflection of the joint using a LVDT type probe. We are...
