A blog for Robotics, Ideas and Fun!
It was a great experience for the girls. Although most of the participants are from high schools, Elsa and her friends are having lots of fun!
Our coding seems to be working for the line following, color detection and obstacle detection. However we definitely need to improve the design for the ramp, and we are not really prepared for the rescue zone.
Look forward to the Robocup America in October 2026!
We have been optimizing our robot car a lot recently. There are a few new changes:
(1) A new 5 way line follower has been added to replace the original ones because they are too big for such a competition.
(2) The layout has been siginificantly re-adjusted – not sure if we made good choices lol
(3) Some other sensors have been added.
(4) We are having some challenges in recognizing color sticks. Still trying to adjust the hardware and codings.
Time is limited for all these works!
We made it with a bigger structure, added a new universal wheel to it, and adjusted the speed a lot because we were trying to pass the line with the gap in it. It worked out okay but it didn’t improve that much.😅
Our first micro:bit robot follows the black lines!
It was a big success!
LEGO just announced the new FIRST LEGO League (Future Edition) hardware. It’s always interesting to see how these tools evolve to improve the experience for kids getting into robotics. While Elsa isn’t getting this set right now, it’s definitely something we might explore down the road.
For now, our focus is on the M5Stack that’s currently on its way to us.
I’m looking forward to seeing Elsa explore a different side of hardware—moving into a more open, industrial-style platform. It will be a great chance to compare different ways of thinking and building. Can’t wait for the mail to arrive!
I built this myself, isn’t it cool? If you move the adjustable panel, it will play different tunes. I even managed to play “Twinkle twinkle little star”!
This is only phase 1 and let’s see what we can do!
