Mobius 2 Axis Pan & Tilt Brushless Gimbal by markqv

Last crawled date: 3 years ago

Using concepts and pieces form my 3 axis gimbal, I reconfigured the pieces and put together a 2-axis Mobius gimbal that works on Pan (yaw) and Tilt (pitch). For this I am using the same (15mm) gimbal motor from RCTimer with a hollow shaft to help with wire routing. The hollow shaft makes the routing easy without affecting the motion freedom. The motor wires are nice ultra-flexible silicone and you can fit up to three sets through the shaft opening.
After a few design iterations, I printed a few different versions to zero-in on the balance and clearances. It balances perfectly with no added counterweight as long as you have the "C" lens and the Align PU Gel pad. Here is the parts list:
