    Unfortunately, due to the impact of COVID-9, the purchase of many parts will be delayed. The Hall potentiometer was just received the day before (the previous use of low-quality potentiometers caused severe jitter). Metal parts such as the output rocker arm may be obtained later, so the entire progress will be delayed. Good luck with your project.

    After a month of work, the customized output arms are finally ready.

    Two 360 ° Hall potentiometers are used, making adjustment very convenient. The motor power is 350W, with 1:60 worm gear box.

    hey!
    good work! really good looking rig.

    do you have issues with flex or shaking because of the weight of the rigprofiles and the power of the motors?

    would be awesome to see another video in action from the finished seat!

    congrats buddy! :)

    Just something for consideration, effective use of torque falls off rapidly at any more than 40 degrees either side of perpendicular, yours look way over that in this picture:

    I am not sure if I understood your question correctly.
    Do you want to ask: Will the fisheye bearing and connecting rod sway due to the gap? The answer is yes, I am considering adding some damping devices.

    Thank you for your reminder. Wrong setting before.
    It has been changed to the following settings (as shown): when the seat and output arm are at 0 °, the connecting rod is slightly tilted. When the seat at 10 ° and the output arm at about 40 °, the connecting rod will be vertical.
