    Ive never once studied robotics but it seems to me that this sort of thing would be a great introductory course to the subject

    • Klenom
      Klenom 14 days ago +13

      Sorry bro, but this kind of thing is so far away from introductory, introductory robotics are like: open and closing a gate, or lifting up some wheight with a motor. Actually doing robots its on the midterm of robotics, and competitions like this are endgame things.( Sorry for the possible typing errors)

    • Fourth Numeral
      Fourth Numeral 13 days ago +9

      ​@Klenom I think he meant it in the way of being introduced to the potential of robotics during introductory courses. Show students the possibilities, let them imagine the what ifs, and then the basics begin.

      Its actually really not that far out there to use this as introductory robotics, even in a practical sense! Before I went off to college, I participated in a highschool robotics competition that McGill University hosts, which does exactly this. All the equipment is standardized with a few customization options, and over the course of a couple days they introduce the different features and how to write code on the arduinos that drive the little mice, and then you have a sandbox day to try different things with different mazes before you submit your final version for the contest. They use very simple mazes, and you have very few options for sensors, but in my opinion it was the perfect level of challenge!

      In my university it's a class they teach you to code and then at the end you build a micro mouse or a robot that does something like following a path then lifting a can or moving some servos to carry stuff. This class is on the camputer/electrical engineering idk if there is something similar on computer science since they only do coding and stuff while we do hardware and some coding.

    • Anankin12
      Anankin12 18 days ago +3

      ​@Seldom Needythat's to be expected, though. Many of the cool ideas were 2 steps away from catastrophic incidents (ground effect is one such example: it will stick you to the corner untill it doesn't, then you'll be so much over the limit of normal grip that nothing you do will influence the car; and this could happen by chance if even a little bit of air gets in. Nowadays it's not a problem anymore, but the same applies to many other innovations. They could have left in asymmetric brakes tho)

    I got SO excited when you got to the part about turning forces, and I guessed right before you said it that they were creating vacuums to hold the mouse. I’m not usually a very mechanically minded person, and it was really a joy to have an AHA! moment organically like that. I am so appreciative of the ways that you can share other’s passion in such effective ways. I didn’t know or care about robotics in the slightest before this video, but now I’m excited to see what the future holds for micromouse optimization.

  • Investing for your future

    Very cool production and supporting animations. Feels like the next level for these competitions would be to make the maze multi-level with multiple ingress and egress points to the different levels, along with non standard shapes like "circular" rooms and hallways.

  • Bird
    Bird 2 months ago +4

    This could be a truly incredible education tool. A simple version of this could get kids an absurd amount of basic STEM skills. (A mixture of guides and some of the hardest stuff pre-built, but with a lot left intentionally unclear forcing kids to experiment and look at examples outside their class and figure out why things work the way they do.)
    But what's more brilliant is that I'd bet it would be pretty easy to get kids amped up and competitive so they want to do it instead of being made to do ot.

    When you got to the mice that used fans for down force I was sure that you would mention the Chapparal 2J race car by Jim Hall. It used two big fans to remove the air from the boxy, skirted body. So effective that the concept was banned for the next season.

      there was also f1 car with same idea, upgraded? version was being built but loophole was closed before it was finished. called Brabham BT46B which only ran in official race once. and it won by over a half of a minute but after it won FIA declared that fan cars are never allowed in f1 race ever again. but since it was legal when it raced, it kept its 1 win from 1978 Swedish Grand Prix and joined with other cars that have technically 100% win rate.

    I forgot all about this competition, I knew about it back in the 80’s when I first got into the computer industry. Did not follow it as it was out of my area of specialty. So seeing this and seeing how far it has come in such a short time span is mind boggling. Will have to keep an eye on this, there are some really competitive people out there and it’s astounding how the whole field can change over night just from one person thinking outside of the box.
    Seeing all of the major jumps in the technology over the past 50 years is outstanding. Seeing the first time out of the box to what are being used now is crazy, no wonder it’s gained traction over the past 20 years.

      Not really. Keep in mind that the microcontrollers in those robots can do hundreds of millions of computations per second. If any uses an FPGA instead, that could be an even bigger number. From the robots' perspective, it must "feel" like driving at 0.01 mile per hour.

  • Ludix147

    I would have enjoyed some more speculation on what might change in the future of the micromouse robots.
    I can't think of anything obvious that I would improve. Maybe make the algorithm more speed-aware: Tight corners won't slow you down much when you're already going slowly. But honestly, they probably do that already with their fancy path-planning algorithms. Maybe you could do some sort of statistical analysis to uncover common patterns in how the maze is set up and incorporate that knowledge for even faster in-expectation exploration.
    On the hardware side, no idea. Maybe mainly increased reliability of all components? Improved wheel materials? Even more weight savings?

    I love when i stumble upon a sport or a whole ass competition that been around for many years, but i had no idea about 😂. I used to think subsections like this was just a bunch of weirdo's, but it's genuinely cool to see people so interested in something so niche that it grows into something that brings like minded people together to just be themselves. Learned something new today

    Thanks for this very interesting video.
    Many years ago, Richard Browne, who worked as a technician for Bell Telephone, had seen an article published in the company newsletter that described and showed pictures of Claude Shannon's electronic mouse. Knowing that the mouse used telephone relays to control its motions and solve the problem and having access to scrapped telephone relays, he restored some relays and set out to duplicate the whole thing. The original published article did not detail how it was all done, so my friend figured it out for himself. I remember that the memory for each of the 25 cells of the maze area required two relays which recorded the direction the mouse had last left that cell.
    Near the end of this machine's life ,somewhere around the late 1970s, I met and became friends with Richard. I saw the machine myself and was thrilled by how well it worked. Later, Richard went on to build marble machines, intricate wooden machines that allowed a marble to pass through various gravity-driven paths. Sadly, Richard passed away in 2013, but you can still see his videos about some of his marble machines. Although never completed, his grandest machine, called Marble Machine 3, was one of his creations described by Richard in videos here on Clip-Share.

    The fan vacuum concept had to have come from the Chaparral 2J (built in 1970), which was a race car that used two engines; one of which was to create suction for downforce. Rules were ultimately changed to disqualify it from racing and the suction fan would blow a bunch of road debris at competitors behind it. Anyway, it was interesting to see it cross over into this event.

      ​@Heksu OTHERS got it banned, you mean. Poor team for wanting to win while thinking outside the box.

      @Mahyar Shokraeian It's part of my humanity to claw my way out of eating nothing but scraps, and onwards into engineering.
      Saying that feats of science is a waste invalidates people who actually escaped the poverty line through science. It's like telling me that I need to go back down there just because I'm able to feed me and my family now.
      Instead of being derogatory to science, why don't you just inspire people to aim for this knowledge so they too escape like I did.

      So they have already swapped steel to carbon fiber screws or axles or straight to adhesives to save weight? Biggest issue i see with these advances seem to be that its money game to manufacture lightest parts witch require high quality tooling to produce well as having already wealth of knowledge on the robotics. Sure i can plan maybe even lighter mouse with things mentioned, but i'm decades behind on building the software to level where i could even compete.

      In the video, the robot could go from 0 to over 100 kph in 9 milliseconds. While much bigger than the micromice shown in this video, it still seems to be a possiblr mechanism to use if scale down.

    I wonder if they could design one with variable fan speed for straights so there is less resistance and they can get a speed boost on acceleration and then brake boost on de-acceleration. It could potentially save a few ms over the larger courses.

  • TankenkaNeko
    TankenkaNeko 2 months ago

    The applications for this after (considerably) further development are very cool. Imagine these being refined further from micro-mice to nano-mice... something that instead can traverse liquid... and viola... diagnostics in medicine. Or, something that can navigate complex terrain... search bots for people/animals trapped under rubble in disaster zones. While it's certainly useful to have large or complex mobile robots that can do the saving / transporting of life-saving materials or methods... having search/diagnostic/mapping robots are equally important, particularly where time is of the essence. One further application could be in darker cases where people disappear (by natural or nefarious means) and need to be found quickly to be saved.

  • Cheesemaker

    Maybe moving forward by backward and backward by forward, could be a great strategy if the micromouse has diagonal back sensor and front sensor, that allow them to process more data of the path with multiple intersection without the need to rotate to return to the path

      When you think about it, it is actually quite obvious to every car geek.
      There have been tons of ground effect cars, including the chapparal 2j (with a fan), or in formula 1 the lotus 78/79 (with skirts), or the Brabham (with a fan, but different), etc.
