Pivot
6328 A-Frame Pivot
A triple-pivoted A-frame arm with notes on torque analysis, custom gearbox packaging, dead-axle clamping, and serviceable joints.
Mechanism examples
Steal from the best, invent the rest.

Don't be afraid to take inspiration from robots that already solved hard design problems. This library collects in-depth writeups and CAD references so teams can study real mechanisms, compare approaches, and build better designs faster.



























Contribute
This library gets better when teams share what worked. Add examples with images and CAD links, or help turn existing references into Behind the Design writeups with the reasoning, packaging choices, and tradeoffs that made the mechanism work.

These examples go beyond a CAD document and explain why the mechanism was designed the way it was.
