David-LaserScanner laser sweeping mechanism

This project is a stepper motor based laser sweeping mechanism to be used with DAVID-Laserscanner. The design has been done with ViaCAD 2D/3D. CNC G-Code file generated with CamBam.

ViaCAD - [Planetary Gear Box V29

The aluminium box is RS-Components #225-192 (114x89x55 mm).

The stepper motor is used with a planetary gear box of 1:100 ratio. This gives a resolution of 0.018°.

The electronics is based on:

  • Arduino Uno
  • Adafruit motorshield
  • Custom board for laser and light control

The different parts before machining the box:
