4.3.4.1 - onboard laser?

[Rickertsen2]

I don't see the problem with a laser as long as it is weak enough that it will not cause eye damage. There are certian classes of lasers that are rated this way. Also, who says you have to use the entire laser pointer with the battery? There are plenty of places that sell laser dioded meant ot be powered by an external source

you can make up sights for aligning your robot on the field. In the past we used simple things, like drinking straws or a small piece of PVC pipe that were attached to the robot, to look through.

you dont need much, trying to align your bot to within 1/4" on a wall 40 feet away would be a waste of time. If you can repeatedly align it within +/- 1 degree thats probabally the most you need.
