In the summer of 2018, I interned at Apptronik, a rapidly growing Austin-based robotics start-up. While I was there, I did mechanical design and analysis for exo-skeletons, actuators, and humanoid robots. One of the coolest things I got to do was develop the forward kinematic equations for their liquid-cooled biped, Draco.
Here it is in action! Apptronik is a great environment where even a lowly intern has the opportunity to make significant contributions, and I really enjoyed my time there.
