Poll: OpenArm Length Extension Trade-off

[gunyarakun]

Background

We've received multiple requests from the community to extend the OpenArm's reach. We're considering extending the arm length by either 30mm or 50mm from the current design. However, as with any engineering decision, there are trade-offs to consider.

The Trade-off

Extending the arm length will reduce the maximum payload capacity:

• 30mm extension: Payload capacity reduced by approximately 15%
• 50mm extension: Payload capacity reduced by approximately 25%

Your Input Matters

While the final decision will be made by the core development team based on various factors including technical feasibility, use case requirements, and overall project direction, we highly value community input to understand your needs and priorities.

Cast Your Vote

Please vote for the option that best represents your preference AND experience.

Please also share in the comments:

• Your typical use cases for OpenArm
• Whether reach or payload is more critical for your applications
• Any specific reach and/or payload requirements you have (in cm/kg)

Thank you for participating in shaping the future of OpenArm! 🦾

The third option seems a typo, should be 25%?

Thanks for the feedback! I've made the updates.

Alternatively, have you considered adding waist joints? That might also help solve the reachability issue a lot.
