Assembling instructions (Nybble kit)
Assembling Nybble #1: Head Group
Assembling Nybble #2: Body Group
Assembling Nybble #3: Battery Holder
Nybble's servos are connected to NyBoard's PWM pins symmetrically and resembles the nerves along spinal cord.
Though Nybble doesn't have shoulder roll DoF, those indexes(4~7) are reserved for the full OpenCat framework.
Use h for head, t for tail, r for shoulder roll joint, s for shoulder pitch joint, k for knee joint, F for front, H for hind, L for left, R for right, the full joints map of OpenCat is:
Observe the indexing pattern to connect servos with correct PWM pins. Be careful with the signs. The brown wire of servo is GND, while the GND on NyBoard are along the center line.
NyBoard needs external power(7.4~12V) to drive the servos. Make sure you understand positive and negative sign on both the NyBoard's power terminal and your power supply.
Align the 'L' shaped joint tuner as a parallel reference to avoid reading error.
