    I have dismantled my 2dof with traction loss rig and am going a different route. I have 3 eBay crabpot motors with 180 degree hall sensors all setup with ctc arms and such. I have $600 US in this stuff easy plus a lot of time etc. Looking for $400 plus shipping. Ready to mount up to a rig. This stuff was used for a couple of months and worked perfectly. Maybe 5-10 hours on them.

    Also have a ujoint and 1500w 12v LED power supply that had no issues running the three motors smoothly. Would like another $100 for those.

    hi i have a question, what would you need to drive these? can i map them to a arduino?
    Also what size are these motors, meaning the dimension ( will they fit in the spacing of the U-joint)?

    I drove them with an Arduino and 2 dual channel 100a controllers from aliexpress like discussed in this thread: Reasonably Priced 100A Motor Controllers (xsimulator.net) They are also available for sale if needed.

    These are the motors with specs: GEAR MOTOR 12 VOLT GREAT FOR SAWMILL/CRAB POT PULL/FEED/SIMULATOR 75-80RPM 50:1 | eBay

    The pivot is roughly:

    3.25" tall
    3.5" length and width

    You would likely need to build in such a way as to have the motors blow or the upper frame clears them. You can see pictures in the thread while building it: https://www.xsimulator.net/community/threads/2dof-with-traction-loss-in-aluminum.18517/#post-247053

    I ultimately wanted to go with actuators so I tore this setup down. All the parts worked fine though.
