That's what you get with 2 independently controlled wheels.

[@ARankin]

The section about the mouse choosing the longer but straighter path really struck home with me. Too often in map software, and even games with a GPS system, the "shorter" path will be taken, even though the longer path is actually faster when factoring in deceleration, waiting at stop signs, etc. It's really a fascinating area for optimization.

[@victormiranda9163]

when it comes to people and autos in cities, the straightest path is usually better. displacing a block for a better street can improve, the issue is top speeds are limited. it is fun to optimize

[@schwarz8614]

Thats actually not true, modern gps factor in that too.

[@mikefochtman7164]

Totally agree. The 'trick' seems to be able to assign the correct speed/ acceleration times. Doing a 'flood fill' to find the route is one thing, but doing a second form of 'flood fill' where you label each position with an estimated time-to-goal sort of distance.

[@mikefochtman7164]

@@victormiranda9163 And we've all been there where we think, "I need to turn left at some point, which intersection would be the best place? At the light where there is a left-turn signal? Or maybe one block BEFORE the light where I won't be stopped by the light but maybe there will be a gap caused by the light where I can turn left even quicker?" Or do I just make three right turns? lol City driving, you quickly find yourself thinking about things like this and trying to remember what works.

Lol it went better than I was expecting this first term, but I didn't win. I wasn't last either though. There are three more terms to go. Although, I kind of dislike the software we're using. Bad and glitchy interface for the EDA part. The coding software lacks modern features such as multi line editing, static analysis, code suggestions and snippets, and has a dated UI. For the EDA software I can only compare it to my experience using programming software since I don't know much about EDA software. Is it all so bad? The one we're using is Fusion 360. I'm honestly astonished it is paid software. Thankfully we're on a free student license though.

[@Hellsong89]

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.

[@josephwatson4616]

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 KZbin.

I havent seen this pop up here yet but Theseus is a pretty good name for essentially the precursor to AI. The Theseus' Ship paradox goes like "if we replace every single piece of a ship over time, can we still call it the same ship?" Because if you compare the final version to the first version, literally everything has been swapped out and yet, on an individual basis, the majority of the ship has always stayed the same. We build out home tower PCs on the same grounds. And while the core idea of a mouse solving a labyrinth has remained the same, pretty much every component of the original Theseus has been improved on, swapped out or both.

When the guy you were interviewing said "you come along one day, you see everything and you go "huh. that doesn't look to hard, i could do that,' but then you find yourself sucked into a deep and rewarding hobby" i felt that in my bones.

And I want to try the fan concept from micromouse in a slot car first, to see if it even works with our tracks (wooden tracks with a routed slot are often smooth, but the majority of my races are on plastic track that has imperfections... the smooth plastic sheet from the downforce demo in this video would be a dream to race on!)

I love that Red Comet got there faster than the other mouse by actually doing what racing drivers do and taking the *racing line* to the goal, ie. maximising top speed through the straights and minimising speed loss by taking fewer turns. Brilliant. The fact that that consideration doesn't seem to have occurred to any of the other competitors before then tells you something quite deep about knowledge: you don't know what you don't know. There will always be 'unknown unknowns'. Saying 'we've reached our limit, we've solved all the problems there are in this subject' is a failure of imagination.

How do racing drivers take fewer turns if they're racing the same track?

[@willp8812]

​@@FancyUnicorn Racing "line" is important because the track width is usually 2x - 5x the width of the car. The most efficient use of available grip comes from maximizing the radius of each turn (although there are exceptions) by moving across the track. For instance, the "racing line" entering a left 90-degree corner would have the driver start on the right side of the track approaching the corner, move to the left during the turn while striking the inside left apex, and end up back on the right side of the track on corner exit. This "line" maximizes the turning radius, and is much faster than staying on the left side of the track for the entire turn.

[@rdyer8764]

Some History: The first Micro Mouse competition was won by former colleagues of mine at Battelle NW in Washington State. They had a 3-step algorithm - 1) Random Walk through the maze, 2) Explore every square (and walls) not encountered during the first run, 3) Compute and drive the shortest (distance) path. Of course the early mazes were much smaller, and they were also less complex so that a mouse with no smarts could execute the wall following algorithm. The fastest (time) mouse the first year used that technique. The microprocessor they built was from what Intel called "Floor Sweepings" - fully functional, but cosmetically defective chips. These incredibly talented engineers were the first in our department to put together an embedded system as I remember. It was a FANTASTIC place to work full of innovative and amazingly personable people. Best job I ever had! Our group's claim to fame 5 years later was to create the world's first self-contained Rubik's Cube solving robot. Just like the first Micro Mouse, Cubot's time of 2:40 has been eclipsed many times over. Still...there's a nostalgic feeling that grabs me every time I see one of these mouse competitions...

The really interesting part of this for me, as a motorsports fan, is the fact that so much of the innovation has followed a similar path to motorsports. The famous Brabham BT46 "fan car" was a F1 car that had a fan attached which sucked it down to the ground, providing greater downforce and cornering. It debuted in 1978 and was banned after a single race (which it won).

​@@tthurlow thats not really the issue that keeps motor sports from doing crazy stuff like they will try in this competition. While yes innovation in motor sports is expensive, we've seen over the decades the insane amount of money companies will spend to innovate to win a race. The issue with motor sports is the fleshy meat bag operating the vehicle. If a little mighty mouse robot runs into a wall at 50 mph, catches fire and goes pop, it's kind of funny and everyone might be out some money. If an f-1 car goes airborne doing 250 mph into the bleachers because Mercedes was allowed to do whatever, you could easily see a large amount of human casualties. A great example is the old group B rally circuit where there where minimal rules for the manufacturers. It got wild, the cars where insane, tons of innovation and lots of death and injury for the short time it existed.

[@InZaneRaptor]

Oval circuits are not like other race tracks. Some tracks don't necessarily have "banked" turns, in racing it is referred to as a corner having camber, as the wheels of a race car utilize negative camber angles to optimize the contact patch when cornering, negative camber is when the top of the wheel is closer to the center-line of the car than the bottom, improving lateral traction when the suspension and wheel is loaded during cornering.

This reminds me of an old book in Reid Kerr Engineering College I found 1970 +/- one year. Logic behind mechanical mice. It described 3-wheel self propelled mice which would not fall off a table. There were two tables considered. One had a slightly raised edge, the other had none. The latter had two sensors, one to detect a drop ahead of it and the other to detect a collision. A collision in either or a detected drop in the latter type would trigger a right turn. Now that I have seen computer mice I wonder if Xerox Labs had any input. But the book looked quite old, although 10 years would be old.

I think that because we have Kosen Robocon which is televised on NHK every year, it may be a little bigger deal than the micro mouse.

To optimize, the mice would need to hug an outside wall, than turn in a bit early to just kiss the inside wall, then barely miss the next outside wall.
