The Programming Task
  • Calculate the robots position (x,y,?) out of an
    initial position and the sensor readings from the
    wheel encoders.
  • Differential Drive with
  • Number of encoder signalsper round n60
  • Wheel diameter r57mm
  • Wheel distance l97 mm

6
The Programming Task
  • Do your implementation in
  • ct-bot ? bot-logic ? behaviour_ar.c
  • void update_Position(void)
  • Input
  • Counted encoder peeks
  • sensEncR
  • sensEncL
  • Output
  • Robots position
  • positionX
  • positionY
  • positionR
  • More hints in the code
