Typical Build Roadmap
- Concept & Planning
- Define scale (1:1 or 1:4) and weight limits.
- Sketch movement requirements (jaw, neck, tail, limb articulation).
- Create a preliminary budget spreadsheet (≈ $800‑$1,200 for hobby‑grade parts).
- Structural Frame
- Use 80/20 aluminum extrusion or steel tubing.
- Follow the free CAD templates from GrabCAD.
- Assemble joints with bearing‑type hinges to reduce friction.
- Actuation System
- Select servos: Hi‑Tec HS‑785HB (torque ≈ 12 kg·cm) for jaw, smaller micro servos for fingers.
- Integrate planetary gearboxes for higher torque at lower speed.
- Implement PWM control via Arduino Mega or Raspberry Pi 4.
- Power & Electronics
- Use a 12 V LiPo battery (5,000 mAh) with a DC‑DC buck converter for 5 V logic.
- Add an external MOSFET driver to protect microcontroller pins.
- Include a current‑sense resistor for real‑time power monitoring.
- Sensor Integration
- Mount ultrasonic distance sensors at the head for obstacle avoidance.
- Add flex sensors on the spine to simulate realistic bending.
- Feed sensor data back to the controller using I²C or SPI protocols.
- Programming & Testing
- Write state‑machine code to sequence jaw open/close with tail sway.
- Use a potentiometer on each servo for closed‑loop feedback.
- Test under load for at least 4 hours to
