build_steps:
  - title: 3D print the arm parts from the STL files using Hyper PLA
  - title: Assemble the frame and servo joints with 2mm x 10mm screws
  - title: Wire the four SG90 servos to Arduino pins 6, 9, 10 and 11
  - title: Build the custom USB power supply and connect its GND to the Arduino GND
  - title: Upload the test sketch and verify each servo
  - title: Upload the main sketch and calibrate the joints and gripper
