TPU is useful in robotics for grippers, dampers, cable guides and compliant contacts, but it should not carry the full structural load. Geometry and attachment determine durability.
Applications
- Gripper contact.
- Damping.
- Cable guide.
- Protective cover.
Design
Use a rigid frame with flexible contact zones, progressive thickness and rounded transitions. Validate cyclic movement.
Testing
- Grip.
- Recovery.
- Fatigue.
- Wear.
| Part | Design | Test |
|---|---|---|
| Gripper | Contact | Grip |
| Damper | Compression | Fatigue |
| Guide | Flexibility | Cycles |
| Cover | Thickness | Impact |
Common engineering mistakes
- TPU as the main structure.
- Only choosing by Shore.
- Sharp transitions.
- Static test only.
- Ignoring mounting.
Buyer checklist
- What motion occurs?
- What load and cycles?
- Is a stiff frame needed?
- Is TPU dry?
- Was the assembled robot part tested?
