Bowden Cable Assembly

What is the Bowden Transmission System?

The bowden transmission system allows transmission of torque from motors mounted at the waist to end-effectors placed at the joint (e.g., the ankle or elbow). This allows researchers to focus on developing innovative end-effectors without spending time developing a baseline transmission approach. Currently, end-effector designs outlined in the primary manuscript are not documented; however, we encourage you to stay tuned for future updates that will address this! 

Important note: For lower (up to 20 Nm) torque builds, you can use the 1/16” cable with 5mm bicycle sheaths. For higher (up to 35 Nm) torque builds, use 3/32” cable with larger sheaths (Lexco 7MM2P). The larger cables and sheaths are significantly stiffer, but you can mix-and-match. For an ankle exoskeleton example, using the larger cables on one side for plantar-flexion assistance, and the smaller cables for dorsi-flexion assistance on the other side.
