Strategies
Corridor competition
For the corridor we decided to develop a simple code, possibly recyclable for the maze navigation. The robot has to stay approximately in the middle of the corridor, which has been divided into a safe zone and a dangerous zone. PICO compares two distances measured from the laser scans and based on their difference it will correct its orientation by rotating to the left or to the right. During this this rotation a small forward velocity is fed to the base in order to get a smooth movement. When he detects the exit, he starts the turning maneuver.
First test (19/9)
Experiments are performed on PICO, however the testing did not go as planned. PICO had to be resetted sometimes and did not respond to our commands as expected. The data shown in the terminal however, did show the proper values while running.
Second test (20/19)
We experienced again some connection issues. We were able to move the robot, and again some delay seemed to occur. The discharged batteries have put a premature end to our tests.
Planning & Work division
- How to use the PICO robot (19/9)
- Work on the core functions that will allow the robot to fullfill the corridor task (23/9)
- wall_following
- exit_detection
- take_exit
- motion
Each member of the group will focus on a single function
