This link above will give you some assistance with using the light sensor to follow a line.
It will also give you some assistance with calibrating your light sensor. At times, you light sensor stops reading values correctly and needs to be recalibrated. This will re-set zero percent to zero and 100 percent to 100. If your light sensor does not appear to be working correctly, go into "port view" and check it. Aim the sensor at something black. It should return a very low reading - single digits or low teens. Aim it at something white. It should return a high reading - 80 to 100. If not, it needs to be re-calibrated.
BattleBot Plan and Guidelines
BattleBot Plan and Guidelines
Students will successfully complete and demonstrate to the teacher a challenge board challenge using the line-following capability. <-- This link explains how the robot interprets light and dark in order to follow an edge of a line.
2. Students will create a program that causes the robot to remain inside the battle bot game ring.
3. Students view the slide show to the left, and summarize the main points.
4. Students will choose one of the "Lift and Grab" tutorial videos to follow and build. After successfully building the Grab and Lift mechanism and showing it to the teacher, the student may make modification. Find ideas to get started HERE.
5. Students will use the Linear Actuator video tutorial to build a linear actuator of their own design. This must be shown to the teacher. There is an example one HERE, but you can make your own or search up a tutorial if you wish.
6. Students design and build their autonomous bot in preparation for competing in the sumo ring. Battlebots may not be remote controlled, but must use sensors to remain in the ring.
