Testla
<Group Pic>
Abstract
The Testla project is the culmination of our efforts to create an autonomously operated RC Car by pooling together our experience in software design, hardware design, power systems, and mobile application development. Project development started in February of 2022 and ended in May. (NOTE: One more sentence probably)
Introduction
The project was divided into 5 modules:
- Bridge and Sensor Information
- Motor Operation
- Geological Information
- Driver and LCD Manager
- Android Application

Geographical Controller
The Geographical controller is responsible for determining the position of the vehicle as well as the distance and bearing to desired destination.
Hardware Design
An Adafruit Ultimate GPS breakout module using the MTK3339 chipset is interfaced over UART to the Geographical controller to provide latitude and longitude updates.
TODO: interface and explain compass
Software Design
On startup the GPS module is initialized to provide updates at 10Hz with a 115200 baud rate. Additionally, the Bridge and Sensor controller sends a desired latitude and longitude to the Geo controller over the CAN bus.
The desired and current position are used to calculate a distance and bearing using the haversine formula shown below.
