Developer inquiry: actuator extension and rotation solution

1 reports · 1 sources

A developer asked on Reddit's r/robotics forum whether anyone has seen a solution that uses a single actuator to simultaneously achieve joint extension and rotation of a robotic arm, and is considering using cycloidal gears to compensate for the extra weight and joint torque requirements introduced by the extension section. The post is only a request for solution ideas and gives no specific model, experiment, or validation results, so whether this concept is feasible remains undetermined.

  1. Can a Robotic Arm Use a Single Actuator to Achieve Both Extension and Joint Rotation? A Discussion of Cycloidal Gear Solutions

    A developer asked whether anyone has seen a single actuator achieve both extension and rotation of a robotic arm joint at the same time, and considered using cycloidal gears to compensate for the extra weight and joint torque requirements introduced by the extension section. The post is only a request for ideas; it gives no specific model, experiment, or validation results.
