I’ve just joined this group and don’t own the AL5D yet but the application I would want to use it for is as a Robot ARM strapped to a manakin to simulate a human arm. This would mean the AL5D would be fixed/strapped at 90’ to ground.
The arm wouldn’t need to reach higher than parallel to the ground.
Would it just be the base joint (now acting as a shoulder) that wouldn’t operate as per normal?
Would this actually function at all?
What would it’s short comings be?
What could be alleviated with counter weighting?
If I wanted to do what you are describing I would opt to replace the base rotate with a 1/4 scale servo / bracket. That would be a much stronger solution.
Remember robot arms traditionally do not like holding positions indefinitely when a joint is under a lot of load. People aren’t able to hold things for a long period of time with arms outstretched, and robots don’t like it much either. You must think about these limitations when planning a project.
Park the arm in a position where the work the servos do is minimal. Move the arm to achieve the required task, wave, pick something up, etc. Then return to the parked position.
Your comments are encouraging. Parking/rest/holding issues asside, I take it that the ARM could lift its own weight provided the Shoulder servo was upgraded:
Is the “1/4 scale servo” a servo that is sold Lynxmotion? Sorry, I’m not familiar with this servo reference.
