Repo with KiCAD files: GitHub

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

  • All ultra sonic sensors (Grove, SRF02, and SR04) give relatively unreliable values
  • The compass values highly depend on its location circumstances - you may encounter unreliable values here as well

Since we do not focus the Rover's applications itself, we leave any implementations for sophisticated front and rear distance- or cardinal direction- measurements via additional or different sensors or any filtering 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
  • Buzzer implementation

Upcoming Implementations

  • Bluetooth implementation to allow Android App control
  • Temp. Hum. sensor, Accelerometer, Gyro
