Quantity   Component name
1 × 3D Print each component as specified
1 × (Optional) - Rubber O rings or grippy material I've used my own 3D printed wheels with rubber o rings wrapped around, but you could buy your own wheels or use something else like elastic bands to achieve the same effect.
1 × PCA9865 Servo controller Ideally HAT for raspberry pi
2 × Variable voltage regulator One for 5V devices like the Pi and arduino, another for 7.4V servo power
6 × Aluminium servo horns (MG996R)
8 × 10mm diameter bearings (5mm internal diameter) x 4mm 2 of these are used in each joint and are pushed fitted in to the Leg sections using a vice or with softened first with a hairdryer.
12 × 10mm M3 bolts Used for securing stepper motors - Please overbuy
12 × 15mm M5 bolts Used for securing the body - again please buy more as I'll be using more as the project progresses
4 × 30mm M5 bolts These are used for the joints and pivots
16 × 15mm M4 bolts To attach servos to the legs
20 × M5 locknuts and washers You'll need at least this amount
1 × Raspberry Pi Zero W
1 × Arduino Uno
6 × MG9966 Metal gear servos
2 × 38mm NEMA 17 stepper motor
2 × A4988 (OR DRV8825) stepper motor driver
