2018 Japan Robotrace contest, 1st prize Cartis04.8 by Hirai san, 11.166s

The whole length of the course is 31.7m, which means the average speed of Cartis04.8 would be around 2.84m/s. Check www.ntf.or.jp/mouse/micromouse... for the course configuration.

Excellent, well done! 😎👍👍

Very cool!

[@dreamerson]

cool!

Nice

Where's find material and koding?🤔

[@e-clubmultimedia372]

I want to know what technologies they use in that car. Can someone tell me?

[@darkphoton_15keV]

I am not an expert but based on other projects I've involved with. If you want only extremely low-speed track tracing, you probably only need several light sensors (to tell black and white) and some simple hard-coded logics (when to turn in which direction, how to navigate through the crosses). So a small customized PCB with several simple logic chips should be enough. If you want the performance in the video, you probably want to add the following functions: memory of the track, curvature calculation for maximum speed over the corners, denoising those dots at those turning points, and probably a little bit more. I don't think you need any extra sensor, but maybe a control unit similar to an Arduino is necessary to implement all these functions.

Can you provide the kit I want to buy and learn also can you teach me

[@suhu9379]

The robot was designed by a Japanese, not me😅. Sorry.

[@olivvapor4873]

Why are the dots on the track for please ?

[@viniciusfriasaleite8016]

They are for begining and ending of the curves

[@olivvapor4873]

@@viniciusfriasaleite8016 thank you !

[@SassePhoto]

If the line is traced, why not run fast the first time? Or is there a learning mechanism here?

[@pagedavid4344]

Maybe to make sure that he is on the rank in the competition?

[@cktken3336]

Because the first time it goes through, it doesn't know if it can slow down enough in time to not flip over if it takes a turn too fast. After the first run, it knows exactly how fast to go, and when it should go fast.

[@paulweerheim]

First run is to learn, runs afterwards are to race.

[@moco5360]

有人知道，開發的主機是什麼嗎？是 Arduino嗎？ 有點興趣想搞一臺😁

Which Sensor have they used for such Accurate Line following? Thanks In advance

[@andreagiudici926]

I would say some light sensor and/or something that works with reflection.

[@paulweerheim]

Its not necessary to be really accurate. The key is in the robot movements and memory. The first run it learns the path, the runs afterwards it races it.

I am interested in robots please
