For implementation details, please refer to our paper: http://lab.plopes.org/#harvesting-haptics

• schematics: circuits used on PCB.
• code: containing Arduino code for NRF controller, Python code for connecting to NRF controller, and Processing code for intermediate program communicating to any Unity application (VR).
• waterjet: mounting plates and the big gear were cut using a waterjet machine, with 3mm Aluminum. Parts are assembled using M2 and M3 screws, mounted on elbow brace (MOSCARE).
• 3D printing: three gears are 3D printed with PLA.
