A very simple 3-wheel robot that can be managed from an external application.
The goal of the experiment is trying to solve, in simplistic and home-made way, some of the challenges of having an autonomous rover.
- Follows a given course using a compass and avoiding obstacles.
- Reports current status and position through Bluetooth to an external application in JSON format.
- Accepts commands sent from external application.
- Operates in auto and manual modes.
- 2 x FS90R Servo motors.
- 1 x HMC5883L Digital Compass.
- 1 x HC-SR04 Ultrasonic sensor.
- 1 x HC-06 Bluetooth module.
- 1 x Led RGB.
- Runs on a RaspBerry Pi 2 + CSL Bluetooth USB Adapter micro V4.0.
- Receives monitor data from robot using Bluetooth (heading, course, obstacle, position, state, etc.)
- Sends live monitor data using websocket to client AngularJS application.
- Stores received data in database (so it can be retrieved later).
- REST api that can be used to retrive monitor data or to send commands to robot.
- Display robot monitor data using HighCharts.
- Charts are updated in real-time as live monitor data is received through websockets.
- Allows the user to send commands to the robot:
- Set Auto / manual mode.
- Go Forward / Left / Right.
