Robot – Strategy
1st task: | Using the cameras and laserscanner information, rows are detected. This information will be converted using sensor fusion and PID controllers to motorcontroller commands. |
2nd task: | Same as task 1, but now with additional info of which rows to drive in. |
3rd task: | Probably using gmapping, otherwise using odometry and xsens combinated with the information from the cameras |
Free style: | Detect a parking place and park the robot with trailer backwards in that spot. |
Robot – Investment
Work hours: | 260 hours per person, thus 1040 totally |
Components: | 3 cameras, motherboard and processor, Arduino Uno, potentiometer |

Problems / Challenges
Previously the robot was controlled using LabView. It was a challenge to rewrite the whole software into ROS without any prior knowledge in ROS. |
