Proud to share the results of our engineering team’s recent work at https://huggingface.co/Robonine:
• Together, we applied advanced topology optimization to redesign critical brackets of the manipulator, achieving a 57–76% reduction in structural deflection.
• Our updated model also demonstrated a major stress decrease — from 93 MPa down to 25 MPa — all while staying within the allowed weight increase.
• Although we didn’t fully reach the target tip deviation of 0.3 mm (best achieved: 0.41 mm), the project gave us valuable insights and a solid foundation for the next design iteration.

We tested the mechanical backlash of the Feetech STS3250 servo.
Using an 86 mm lever arm, we measured a tip displacement of 0.64 mm, which corresponds to an angular backlash of approximately 0.43°.
According to the datasheet, the maximum allowable backlash is 0.5°, so our measured value of 0.43° falls within the specified limit.
