Meetings
(Global) Planning
Week 1 (2013-09-02 - 2013-09-08)
- Installing Ubuntu 12.04
- Installing ROS Fuerte
- Following tutorials on C++ and ROS.
- Setup SVN
Week 2 (2013-09-09 - 2013-09-15)
- Discuss about splitting up the team by 2 groups (2,3) or 3 groups (2,2,1) to whom tasks can be appointed to.
- Create 2D map using the laser scanner.
- Start working on trying to detect walls with laser scanner.
- Start working on position control of Jazz (within walls i.e. riding straight ahead, turning i.e. 90 degrees).
- Start thinking about what kind of strategies we can use/implement to solve the maze (see usefull links).
Week 3 (2013-09-16 - 2013-09-22)
- Start work on trying to detect openings in walls.
- Start working on code for corridor competition.
- Continue thinking about maze solving strategy.
Week 4 (2013-09-23 - 2013-09-29)
- Decide which maze solving strategy we are going to use/implement.
Week 5 (2013-09-30 - 2013-10-06)
- To be determined.
Week 6 (2013-10-07 - 2013-10-13)
- To be determined.
Week 7 (2013-10-14 - 2013-10-20)
- To be determined.
Week 8 (2013-10-21 - 2013-10-27)
- To be determined.
