This little robot can be a lot of things. You can make it as a remote controlled rover with just a couple ESCs and a radio, or you can make it fully autonomous with a Raspberry Pi Zero!
Basic assembly requirements:
- 1x - Pololu 22T track set
- 2x - N20 Gear motor (6V; 180 to 300 RPM recommended; encoder optional)
- 4x - M3 x 15mm machine screws (for motor mounts)
- 5x - M3 x 8mm (for body mounts and battery cover)
- 2x - M3 x 10mm (for body mounts)
- 11x - M3 nuts
Advanced assembly requirements:
- Above parts plus:
- 2x - M3 x 10mm (for charger dock bumper contacts)
- 4x - #4 x 1/2" wood screw (for RasPi Zero board)
- 2x M3 x 15mm (for charging dock)
Electronic parts selection can be anything you want. Here are a couple recommendations.
Basic RC electronics:
- 2x - 10A brushed ESCs with BEC.
- 1x - 2+ Channel receiver with transmitter
- 1x - 2S LiPo (whatever fits)
- Optional: FPV camera.
Advanced telepresense electronics (what I used):
- 1x - Raspberry Pi Zero W
- 1x - Raspberry Pi Camera; 160° FOV with 2 LED modules
- 1x - 16cm FFC Cable for Raspberry Pi Zero Camera
- 1x - Dual L9110S motor driver module
- 1x - 1S Lipo
- 1x - USB 1S LiPo Charge and Protection Module
- 2x - 2-5V to 5V, 2A DC-DC Step-Up Module (One should be enough, But I paralleled two for more current.)
- Optional: conductive foil tape for charge bumper and dock.
- Optional: I2C ADS1115 ADC and ACS712 5A current sense module for battery monitoring and stuff.
- Optional: DIY LM4871 audio amp (for speech synthesis)
