I joined Direct Drive Technology in October 2021 as the North American Representative for Diablo. In the beginning, I worked on making Diablo move again in the United States using locally sourced parts including battery, BMS, and charging setup. I redesigned the Diablo battery holder with a quick swappable mechanism to prolong the operation time from 20 minutes to as long as possible giving backup batteries, and allowing for longer demo sessions. To ensure the security of the new design, I performed FEA on the mechanism and finetuned the PID controller on ROS to adjust for the altered mass and center of gravity.

Then, I visited and pitched to companies and institutions interested in Diablo. Ultimately, I led the company to attend the International Conference on Robotics and Automation (ICRA) 2022, from planning to execution.
