Hello there, My team is using the color sensor to build a line follower program similar to the one in the tutorial. However, the robot misbehaves about 3/10 runs. 7 runs are perfectly fine. Has anyone else experienced this? Any suggestions?

Hi all,
Blue River Technology is running a FIRST Fun Day on September 24th from 11:30am-1pm at their Santa Clara facility and are looking for an FLL Challenge team to come demo and show off their achievements. The employees at Blue River are super interested in starting their own teams as well as finding opportunities to mentor. We understand that this is quite late notice and that it may be hard to get out of school that day, but it is a great possible sponsorship opportunity as well as a great outreach opportunity. If you are interested, please email me (jaye@playingatlearning.org) or Avanija, our Outreach Volunteer (avanija.komarraju@gmail.com).
Thanks!

Does anyone need extra Engineering Notebooks for their team? We have 6 more than we need for our team members.

Hey everyone, we’re the Cookie Bots, a rookie troop of 5th grade Girl Scouts from Danville.
We’re just getting started and very excited to meet other nearby troops that may be interested in meeting up as the season gets going.

Hello my son & I just saw the great FLL presentations in Fremont a weekend or two ago!
Are there any teams available to join near San Jose? We’re South San Jose. I have a 10 year old (4th grade).
Thank you!

Hi Lini,
I suggest using the following questions with the kids:
1) What is the color sensor reading specifically?
2) What is the color sensor comparing values to?
3) How does the color sensor know what is 0 or 100% reflected light intensity?
4) What environmental factors on the robot, attachments or in the room, could be affecting light?
5) What measures could be taken to mitigate outside factors?
6) What actions could be taken to set correct light readings?
7) What positioning is optimal for the color sensor to perform reliably?
When the kids think about those then they will most likely find the solution.
You could also have the kids follow the color sensor and line following tutorial on ev3lessons.com because they cover shielding, calibration and positioning which are the most common issues.
Try using “on for seconds” mode instead of rotations or degrees in move steering block. I think misbehavior is caused by the occasional malfunction of motor rotation sensor.
