    Hi guys. I go to upgrade my 2 dof to 4dof. For the moment the idea is to put one motor for corner. In a future i Will build a new chasis with 3 dof + traction Lost but now is more easy mod the chasis with one motor for corner. I have one sabertooth 2x60 and one sabertooth 2x32. I Hope this is not a problem for don't are the same sabertooth. I go to use 2 Arduino, interface 1 and interface 2 in simtools. The configuration of axis is axis 1 and 2 in interface 1 and axis 3 and 4 in interface 2. The schematic conection of the Arduino is the same in 1 and 2? I need to change some conection in Arduino? What forces can i apply in a 4 dof whith this construction? Motor 1 and 2 is in the front or behind?
    Thanks for help guys.
    Have a nivel day

    Hi :)
    You have an idea how that construction will look?
    If You want to add 2 actuators I supose You want to eliminate joint, in other way that will nothing change.
    Constructions 2dof balansing on joint, redece power needet to operate. If You want put higher frame on 4 motors only - will be necesary more powerfull motors. I use 200-300w motors and they are not so strong as I have found out :)
