5.1. Servo wiring

Connect the wires of servos to the NyBoard servo pins as below. They follow a circular symmetry. Notice the skipped pins between the head and leg servos. They are reserved for our future robots with more joints.

The black wire (GND wire) should be closer to the board.

Bottom view:

Insert the infrared receiver under the back plate so that the sensor can expose to the outside.

Make sure that the wires go into the body, bypass the columns, then plug into the servo pins. Arrange the wires so that they don't get in between the servo plugs and the body frame. NyBoard should be leveled on the four standoffs. Use four M2x8 self-tapping screws to fix the NyBoard.

5.2. Battery

Insert the battery's plug into NyBoard's anti-reverse power socket.

Hold the button of the battery for 3 seconds to power on the battery. If the LED on the battery lights red, recharge the battery until it turns green. The blue and orange “eyes” of the Petoi logo on NyBoard should light on.
