5 🔌 Connect Wires
"Everything is connected." 🤝
Connect the wires of servos to the NyBoard servo pins as below. They follow a circular symmetry. Notice the skipped indexes between the head and leg servos (1~7). They are reserved for our future robots with more joints.
The black wire (GND wire) should be closer to the board.
Inserts 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 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.
Although the BiBoard has only 12 pins, the joint index numbers are configured in the same order as the NyBoard. The connection between the joint servo and the pin is shown in the figure below：
In the calibrated neutral state, place the head as close to the central axis as possible and insert its servo shaft into the servo arm of the neck.
Press down on the head so it is firmly attached to the neck.
Install upper leg and lower leg components to the output teeth of the servos when the Bittle is powered on and in the calibrated neutral position. Please keep the torso, upper leg, and lower leg installed vertically as much as possible, and do not install the lower leg backward, as shown in the picture.
Measurement and installation can be carried out with the aid of a triangle ruler or the L-shaped ruler included in the kit.
