Chassis prototyping
Aimed to develop ballbot wheelchair chassis that support a payload of the seat, electronic devices, motors, and human rider
Chassis prototyping: Project
Payload Support Structure
Designed the structure to test ballbot load-bearing capability
Utilized Solidworks Finite Element Analysis (FEA) Simulation in designing an aluminum extrusion structure to hold 50 lb weight plates to simulate ballbot weight carrying scenario
Chassis prototyping: Services
Design of Electronic Housing
Applied Design for Assembly (DFA) in iterating the electrical housing design enhanced mechatronics mounting locations, and created space for wire management
Initial recognition of the individual electronic components and evaluate the current drawbacks
Ideations evolotion and prototype testing of laser cut acrylic boards assembly and 3D printing Integrated Design
Chassis prototyping: Services
Unconventional Motor Configurations
Designed new motor configuration to better control the spherical wheel
Used Solidworks and Topology Optimization for twisted angle motor configuration to better control longitude motion of the ball, modified the bearing housing design to enlarge its loading capacity with mounting guidance of bearing fits and clearances
FEA Result
