Ricardo Castro

- Designed and simulated a human-scale legged robot by iterating between CAD, MuJoCo-based dynamics, and PD controller tuning to evaluate locomotion feasibility - Scaled link geometry and mass properties from a smaller platform to preserve dynamic behavior under nonlinear scaling effects, informing mechanical design decisions - Developed a CAN-based motor control pipeline on Raspberry Pi and fabricated lightweight leg prototypes using carbon fiber rods and high-tolerance 3D-printed joints

- Led the end-to-end design and construction of a large-scale stage set, translating artistic requirements into structurally sound, fabrication-ready designs under strict safety and timeline constraints - Managed a 30+ person build crew and ~$2K budget, coordinating materials procurement, fabrication workflows, and on-site assembly to deliver on-time for live performance

Working in the NeuroMechatronics Lab under Professor Weber

- Contributed to the mechanical design and prototyping of a wearable mechatronic system, translating human motion into reliable mechanical behavior - Iterated on custom mechanisms and rapid prototypes, balancing kinematics, comfort, and manufacturability

Lab assistant TA for Fundamentals of Mechanical Engineering (24-101), overseeing lab projects and assisting students with their assignments. Provided guidance and support to help students successfully complete their lab work.

- Programmed and executed laser and MIG welding demonstrations, adjusting parameters based on wire material and behavior to achieve stable, repeatable welds - Created a modular fixturing table to support multi-angle welding setups, improving accessibility and consistency across demonstrations and experiments - Supported advanced manufacturing workflows using CAD/CAM and CNC machining, balancing structural rigidity, thermal exposure, and usability in an applied research environment
