4-DOF Robotic Arm

Four servo joints reproducing repeatable poses and a safe neutral position. Four servo joints reproducing repeatable poses and a safe neutral position.

Components

  • Arduino
  • 4 servo joints
  • optional gripper

Build steps

  1. Inventory the board, actuators, sensors, and power rails listed for R03.
  2. Build and inspect the low-voltage wiring against the supplied connection diagram before connecting actuators.
  3. Flash the firmware, run the startup self-check, and record the printed board and firmware version.
  4. Calibrate the sensors and limits, then run the acceptance tests at the lowest safe energy level.

Test and expected result

Validate joint limits, pose repeatability over ten cycles, and unloaded-to-loaded behavior.

Safety and limits

Guard pinch points and validate unloaded before payloads.
