6DOF Robot Arm

As the mechanical and electrical robot arm team lead at my design team UBC Open Robotics, I had the opportunity to lead a team of 7 engineering students through a project lifecycle from concept to 3D printed prototype. This involved setting timelines and leading design reviews for both mechanical structural design and electrical circuit design.

What did I do?

• Led multiple design reviews involving checks for FEA, DFA, and DFM, leading to reduced stress concentrations and project lead time by 1 week.

• Analyzed stress and deformation with FEA in structural frames, reducing weight by 20% and minimizing deflection by 65%.

• Tested 3D printing tolerances for print overhang angles and hole shrinkages, ensuring DFM compliance.

• Selected optimal motors, motor drivers, microcontrollers and sensors such as encoders and IMUs.

• Assessed application needs and selected components according, including motors, motor drivers, encoders, MCUs and IMUs.

• Assessed material selection and selected a hybrid design involving both PLA and PETG.

Skills:

• CAD (Onshape)

• FEA (SolidWorks)

• FDM 3D Printers (Bambu Lab P2S)

• Hand Tools (screw driver,

• Part Selection (Motors, Bearings, Pulleys)

• Project Management
