In collaboration with Graduated Industrial Design at ArtCenter College of Design in Pasadena, CA.
PROJECT OBJECTIVES
Create a rubber band powered radio controlled race car to complete mutiple race tracks
Brand the car
Involve the community through a partnership with a local nonprofit organization
This is the key to powering our drivetrain. The 60' rubber band is fixed one end to the aluminum pipe and the fixture body.
First iteration testing our drivetrain assembly.
Fixtures to test differences between drive shaft diameter and band organizing end caps.
Fixing each assembly to the table to quantify torque while keeping rotations constant.
Second iteration of car with laser cut MDF. First implementation of servo motor for steering tests.
Midterm exploration of external rubber band orientation. First implementation of clutch assembly as seen. Bands are lubricated with silicone oil to minimize friction.
Finished midterm exploration. Proved that external bands was not successful, created too much tension squeezing the shaft and ended up not storing much power.
Soldering electronics onto final car.
Lathed aluminum clutch assembly with microbearings and a rod to stop shaft rotation.
Ground clearance check of complete car assembly. F1 slicks were used to maximize traction and surface contact. Race day would be very hot and allow max grip from hot tires.
Minimizing weight and adjusting steering based on Ackermann's Steering Principle.
Render of finalized cover design.
Painted side profile.
Drag race prep run.
