Single Arm Motorized Exoskeleton

SAM-E is the first prototype of our upper-body exoskeleton system. It was designed with the goal of increasing the strength of the elbow proportionally to muscle signals from the biceps and triceps.

  • Ultimate goal to give 30 lbs of extra lifting strength
  • Does not require the use of buttons/switches to control
  • Costs approximately $1000 in materials to make
  • Has electrical and mechanical stops to ensure the suit cannot injure the user under any circumstance

Documentation is currently being compiled which includes CAD files, circuit diagrams, as well as methodology. While not a step by step guide to producing this exoskeleton, it should give the overall ideas and concepts for building the exoskeleton. A link to a google doc is given below. Please contact us with any questions about our design or implementation at
