I led a team of over 20 engineers in the design, analysis, and manufacturing of a humanoid robot arm capable of sensing torque in millinewtons by using titanium Series Elastic Actuators (SEAs). This sensing technology was used to make the arm a backdrivable cobot. I was responsible for the mechanical design of the arm and end effector, finite element analysis, and inverse kinematics.  We developed a CAN bus architecture using an admittance control loop to move the robot arm to joint angles corresponding to the 3D position of a HTC Vive controller over ROS 2 Humble. 

Below is the 100+ page documentation of the design.
