Custom parts and enclosures

Base plate C

Base plate for the front of the snowplow

Original Snowplow Sketch

Initial frame design which we used to build the snowplow frame. Note, if you are planning to build one based off of our instructions, please get in touch with us as we are in the process of updating our CAD based on our design changes made during construction.

Base plate B

Base plate for the motor control board.

Base plate A

Base plate for the rear of the snowplow

Schematics

Snowplow Control Electrical Schematic

This is a reference schematic for how our snowplow is hooked up to the batteries, fuses, relays, e-stop, on-switch, buck converter, ESP32, motor drivers and motors

Code

RTK GPS With LoRa 32

Arduino
This sketch for Heltec LoRa 32 connected to NavSpark: NS-HP-GN2 : Multi-Band Multi-GNSS RTK Breakout Board. As Base station and Rover.
- Rover rate is set to 4hz to allowed error correction LoRa communication on the same chip.
No preview (download only).

RoverControl

Python
Python scripts to interface Jupyter Notebook codes and Motor controller. It use websockets client to communicate with the websocket server of the motor controller.

SnowPlow Notebooks

Python
Simulation and rover path calculation. AI Obstacle avoidance.
You need to run the Simulation first to calculate the path waypoint.
Simulation for snowplow path: Simulation_map.ipynb, It can run on Workstation or Jetson Nano

Motor control Websocket server

Arduino
Using ESP32 to creating webSockets server to receive motor comments. It control H-bride motor drivers as: BTS7960B or L298n
