I am now working on two reinforced gimbal variants. One of them is based on an ordinary 608 skateboard bearings, another one – GE25 ES-2RS spherical bearing. Both of them will be able to handle springs, rubber bands, pneumatic cylinders, etc. A CJMCU-93 module (MLX90333) is used as a magnetic field sensor.
The fate of GE25 ES-2RS one depends on whether I will be able to prevent it from twisting or not (i have an idea involving _| shaped bracket, 2 pneumatic cylinders, and 2 spherical heads now). If you have some ideas about how to lock “twist axis” of a spherical bearing, please share them in comments =) Here are some pictures of the GE25 testbed and 608-based design.
