    Hello guys,

    I would like to introduce my 2 DOF project made without welding only perforated metal and tone of screws :)
    I'm using:
    SMC3 firmware
    Arduino nano
    Monster motor driver eache channel doubled for more power
    12-15V 50A power supply
    Chinese motors 7716MYGZ , 12V 200W with gear box 16,5:1

    Some pictures from beginning to the end :) :

    Panhard style rods prevent torsional twist and are most commonly used when car CV joint are used as a pivot.

    -@noorbeast@ is right, rods are needed to prevent twist when chair is in motion.
    By the way in picture you see only one, but they are two, on other side as well should be one.

    -I get motors from my friend, what i know he is ordering from china, for two motors i have paid 160€ , not bad deal. They are really quick and powerful.

    Wow, great work.
    Could you make other photos of the entire cockpit available?

    If you use a traditional universal joint then that will not have lateral twist, but if you are using constant velocity joint then a panhard style rod can be used to prevent lateral twist.

    Hello,
    Pedals moves only when you pressing on them :), Just kidding.
    Moving only chair, pedals and wheel base is static.

    I think what you meant to say was that moving the chair position affects the centre of gravity and can add extra strain to the motors. I guess it's ok if you have the motor torque to handle it.
