Fixing the rats nest

Tried to make some videos but Robbie was very unreliable the servo worked then they stopped if you rattle the wire then it worked then the lift motors stopped
clearly its a wiring problem and now is the time to fix it for good. So  i started making PCB's for the various systems each actuator will have its own controller and motor driver connected via I2C  so i need 4 motor controllers for the arms and 8 for the base.

The bottom board is dual sided and will be a combined arduino and l298 motor drive
delivering 6 amps peak. The top middle is just a motor controller it works i just need to add the diodes before it can been used.

The PCB's were manufactured using the toner transfer method the only real problem is the pot and bottom layers are not connected so parts need to be soldered on the top and the bottom this is a small problem with ic holders I just design the boards
with the IC's just having connections on the bottom


  1. Impressive build. I too am working towards a robot and yes, InMoov was my start earlier last year (2012). I like what you are doing!

    Regards, Brian.

  2. nice idea please could you explain us how to build it your PCB' plans and pieces
    thank you
