Carbon fiber reinforced spherical wheel prototyping
Aimed to develop a low-cost fabrication method for a light weight, high load capacity, high torque transmission bandwidth spherical wheel for the self-balancing ball-bot drivetrain with a limited budget
Carbon fiber reinforced spherical wheel prototyping: Project
Initial Evaluation and Fabrication Ideation
Carbon fiber reinforced spherical wheel prototyping: Services
Fabrication Procedure
1. Make/Buy Internal Mold Core
2. Design Leaf Pattern
3. Cut Peel ply, Breather, and Vaccum Bag
4. Cut Carbon Fiber to Leaf shape
5. Mix Epoxy and Hardener
6. Vacuum and Curing
7. Final Outcome
• Small diameter deviation ≈ 1 mm
​
• 10 lbs -> 2.7 lbs Weight Reduction
