Software
- the Rover's documentation (install guide, web-access incl. camera stream, and tracing possibilities), the AMALTHEA model, and the application SW can be found @: git Rover repository
- Rover SD card images are available here
Investigation results
- Sadly, no ultra sonic sensor (Grove, SRF02, and SR04) gives reliable values. Since we do not focus the Rover's application itself, we leave any implementations for sophisticated front and rear distance measurements via additional or other sensors combined with any filtering or similar algorithms to the community.
Included Implementations
- Displaying Hono, BT, and Wifi connection via OLED display
- Website generation for live stream, controls, and sensor data / CPU utilisation visualisation
- Wifi hotspot
- ACC
- Grove / SR04 / SRF02 US Sensor access via wiringPi library but unreliable values
- IR sensor access
- Hono interaction
Upcoming Implementations
- BT connectivity to allow android app control
- Temp. Hum. sensor, Accelerometer / Gyro, and Buzzer implementation
- Bluetooth implementations for remote Anroid App / Joystick control
- New shield on top of motor controller --> one more A/D converter, remove one LLC, attach OLED display
