Calibration Manual

Please download the calibration manual here and additionally take the instruktions below into account:

Please connect the servos to the PCB as follows:

  • Do not use the red marked areas. These are left free and not connected to the Raspberry Pi in oder to allow enough space for all connectors to fit on the board (5 connectors in a row would not fit!)
  • Connect the LED for the mouth to the indicated place.
  • To create the connection of the LED to the PCB Board: Use one of the servo extension cables and cut the side that is not plugged into the PCB. Solder the LED with shorter side to the black (minus) cable, solder the LED with longer side (plus) to the signal cable (usually yellow or wihte). As the LED will blink 15 times per second and therefore has a short on time, it will not break even if for a short time the voltage of 3.3V is bigger then specified for the LED.
  • Connect the left side of the robot servos (5x leg + 3x arm) all to the left connector port and the right side all to the right connector port. This ensures that each of the sites has its own PPTC for shutting down the current in case of high load to the Servos.
  • In case your PPTC is triggered too often, you can replace it with a bigger one or just short it. However the risk is that your servos break in case you do not realize that too much current is drawn and the servos get hot, which can happen quite often, especially if the weight of the robot is on one leg only during programming.
  • It is recommended to connect all servos to the PCB once before the calibration according aboves manual is startet. Connect your Raspberry with the Wifi (see manual above) and connect the PC SW to the robot. then klick on “move & all servos on”. All servos should be set to a position by this. If a servo is not moving, try another connector for that servo and maybe check the soldering connections on the PCB. You can also check if all servos move by moving the sliders in the PC SW around.
