I added a tool arm that mimics the tool arm on the real Curiosity Rover. This video demonstrates the arm movement. The arm has 5 LX-16 servos and all parts are 3D printed.
The tool head has 5 tools
- Powder Acquisition Drill System
- Alpha Particle X-ray Spectrometer (APXS)
- Mars Hand Lens Imager (MAHLI)
- Dust Removal Tool (DRT)
- Collection and Handling for In-situ Rock Analysis (CHIMRA)
I designed and printed each tool seperately, painted them, and assembled into a complete head. The head can be rotated to present each tool as needed.
