Micromouse
- agourlay 2y agoVeritasium published a great video on the topic. https://www.youtube.com/watch?v=ZMQbHMgK2rw https://www.youtube.com/watch?v=ZMQbHMgK2rw
- lqet 2y agoWow, these mice were a lot faster than I expected. In the last part of the video, they talk about fans in the mouse that suck the mouse to the ground to prevent slipping.
- layer8 2y agoSo does the Wikipedia article.
- The_Colonel 2y agoThe first time the video shows a mouse, I was annoyed by them showing a very clearly sped up recording, which made it difficult to follow. Only later it dawned on me that it's real time, not sped up.

- dailykoder 2y agoI think right around the time when I watched his video, I got my risc-v CPU inside an FPGA working, including interrupts. I was very hyped about building such a mouse with it, just to prove to myself that my CPU can actually do something "real". It don't need to be the fastest, lightest, smallest, but a small robot that can solve a maze would be cool. Then I tried to lay things out and realized how much more work that'd be, so I dropped the project (for now). One day I'll build one though! It's only a matter of years, I think.

- anfractuosity 2y agoMaybe the mice could use mmwave to possibly see through maze walls. Or use a little 360 degree camera on a pole. I assume this would be classed as cheating though. Sounds a fun competition :) Looking at the Veritasium video they're crazy fast.
- ziggyzecat 2y ago> Or use a little 360 degree camera on a pole. that made me chuckle. mmwave to see through walls at that size & speed can't be done yet, or can it?
- anfractuosity 2y agoI'm not sure to be honest. http://rfpose.csail.mit.edu/ http://rfpose.csail.mit.edu/ is something I've come across before to detect pose of a human behind a wall. Just found https://www.youtube.com/watch?v=IVpXeO0DYDQ https://www.youtube.com/watch?v=IVpXeO0DYDQ - "Sense the world with TI mmWave: See through rain and walls, and detect small objects", which looks very interesting. Ti seems to make a number of mmwave evaluation boards/chips.
- ctm92 2y agoI guess if you can pull that off while still maintaining that speed, then it's not cheating. Those things are crazy fast!
- GuB-42 2y agoApparently, using a camera on a pole is not cheating, but it is not really necessary to "see through walls", as the robot has 10 minutes to score the best run, from start to finish, giving the robot enough time to explore the maze and figure out the best path. Only the fastest run counts. The pole can make figuring out the best path easier, but at the cost of making the robot bigger and heavier, which I suppose is a problem when you see how fast the top contenders are moving.

- youngtaff 2y agoWhen I was in my teens I can remember people using ZX81s and other computers of the era to build these Unfortunately can't find a picture of one in Google images
- layer8 2y agoHere’s a video from 1982: https://youtu.be/usKAEZ8dmQE https://youtu.be/usKAEZ8dmQE
- soneca 2y agoWhat a find! A video posted 10 years ago, 88 views (after you posted here) and a non- descriptive title or description that is about micromouses How did you find it?
- layer8 2y agoGoogle image search (what GP tried) for “zx81 micromouse” but clicked on “The rest of the results might not be what you're looking for. See more anyway” at the bottom, which surfaced a link to https://forum.arduino.cc/t/its-1982-and-you-need-a-microcontroller-d/182946 https://forum.arduino.cc/t/its-1982-and-you-need-a-microcont.... I tend to take it as a challenge when someone claims they can’t find something on the net. ;)
- The_Colonel 2y agoThe longevity of the competition makes it a nice visual demonstration of technology advances. I can't recall other such examples which would be so accessible and span so many decades.

- yreg 2y agoWe have an autonomous robotics competition (established in 2000) in Bratislava called Istrobot. There are two brackets, one for LEGO robots (mainly for children) and another one for "more serious" robots. Micromouse is one of the categories. It is pretty difficult to do with LEGO, we've tried and always failed. The main problem is that the stepper motors are not precise enough to turn 90 degrees and the error accumulates. We've even tried using a LEGO magnetometer, but it wasn't precise enough. The other categories are easier in my opinion: - Pathfinder: The robot has to follow a drawn line. The line is interrupted in some places, there is a tunnel and there can be obstacles -> in case of obstacles the robot needs to leave the line, avoid the obstacle and find the line again. - Sumo: Two robots start in a drawn circle, once one of them leaves the circle the other one wins. There is a limit on mass and dimensions. (There are some new categories as well, but I have never competed in/watched those.) The competition is pretty great at engaging young kids in programming.
- poopcat 2y agoSo cool. Is it still going on? Would love if it someone livestreamed the competitions
- grishka 2y agoI kinda want to try myself at building one but no idea whatsoever how do I even approach getting started. I've never done any projects that involved custom hardware.
- jackdh 2y agoGive it ago, for as little as £20[0] you can get a Raspberry pit kit which would let you build something similar to a micro mouse, ( I'm not sure if the actually raspberry pi is included/required.)

- grishka 2y agoThat's interesting, I actually have two Pi Zero's laying around I bought ages ago for another project. Though getting this kit shipped to Russia might range from a non-issue to challenging and expensive. edit: yeah it's not on the list of countries they ship to which means if I were really insistent on buying it I'd have to use a mail forwarder which would cost like 2x the kit itself

- raghavbali 2y agoThis is such an amazing way to teach so many of engineering topics. Time to dust off that mechanix kit!
