Easy maze

On the maze board it says 2016. At the bottom of the video it says 2011-08-02. i don't understand from these events. Whats up with that.

@@emindegertekin2047 it’s our fault not to adjust the time setting of the camera 😅.

Yes impressive. Is all the computing power on-board ?

@@GaryMcKinnonUFO yes, in the first run it memorises the maze, calculates the fastest way via an algorithm and than runs it, multiple attempts with removing dust from the wheels that is collected from the maze ground. actually saves .5 seconds with is significant with a runtime of 3.594 seconds

To be fair, the robot doesn't know it's on a uniform grid, it would be fine in a curvy maze.

I was surprised when it moved

@@index7787 how would you know that?

It’s so interesting to see the acceleration

@@doyourownresearch7297 it's smart, and something that happens in real life too, you would want to avoid crossing lots of roads when runnings or rough terrain.

@@ProcuredHat I think he’s scared for his grandkids safety tho

@@greekstreek370 every second you aren't running, it's optimizing its algorithms to hunt you down faster

I did search

he searched for it

@Lemon Pasta she searched for it

be careful tho, we aren't too many clicks away from the melted mouse trap genocide videos...

And now I'm watching them all.

I think I've done something similar in when I attended Ai and machine learning classes, I think that in the first pass the mouse does a basic search for the target (it can be as basic as a breath first search or a deep first search, provided you handle cycles in the latter case) a more refined way could be using some heuristics in the first pass (I'm a bit rusty on that but I clearly remember that there are some strategies that can statically improve efficiency in the first pass). Once the first pass has been done, you have in memory a graph which will certainly include the starting and the ending node, hence provided that you have constructed well that representation, it become as easy as performing any shortest path algorithm of your liking (like Dijkstra's). It's entertaining show to watch a physical thing do the job, but from a computer science point of view these are the basics.

​@@alasuisi It is impossible to use any heuristics in the first pass because you don't know where the goal is. The interesting part of the problem is traveling the shortest distance while path-planning at the same time, as algorithms such as BFS can make your mouse jump have to keep moving across the map. A DFS would work better, but there might be a better algorithm that that.

@@jonathanyang1423 I was assuming that the position of the goal was k known, clearly if that's not the case then you cannot use an heuristic, but also, from the perspective of the agent, there is also no certainty that the solution set is finite, hence a dfs may theoretically never terminate. If we assume that since you can see that the maze is finite and that you are allowed to do informed search, then you can use A* for example with an heuristic as your choice like Euclidean distance or Manhattan distance, also if I remember correctly A* with a constant heuristic basically reverts to BFS

@@alasuisi Yes, DFS may not terminate, which may be a problem. Another problem is that it may not even give the optimal solution. Btw A* with 0 heuristic is Uniform Cost Search (although I guess its the same thing as BFS in this situation). However, A* may not be the best algorithm to use, as it still jumps around a lot (as in you maybe expand one node than another node that is a lot farther away).

Jonathan Yang he should have used a calabi-yao distributed formulation graph to increase the number of f cycles

That's the way I drive ALWAYS I wish more people understood this simple mathematics fact That's why delivery companies in the US always take right hand turns

yeah the turns are deceleration points, I play a lot of steep.

This is one of the basic principles, you want to minimize the number of changes of directions. His route had the fewest changes.

It's the same as going for a run and avoiding crossing busy roads but the ability to decide which is more efficient with minimal to no testing is amazing

I think the route is also shortest

@@michaelblair5146 Machine learning algorithms is something you code

@@michaelblair5146 I could certainly be wrong, but my guess is that this task is not preformed using any machine learning (also known as statistical learning) algorithms, but instead uses mapping, positioning, control and error correction, and shortest path algorithms which have been well tuned for the particular hardware.

@@recurrenTopology yeah, this is just mapping the maze and finding the optimal path (which we have known algorithms for)

no, it is not Machine Learning... it is simple maze algorihtms

@@HummusPvm If you think that this machine(mouse) learns something new and explore maze to find solution using some maze algorithms, yes you are right. If you think that this mouse is using any algorithm from AI branch called 'Machine Learning' then, you are wrong.

😂🤣🤣🤣

Lol, yep

@@insertstupidserialnumberhe2727"Ïm not a robot mouse"

2200: better build

totally agree!

I was still pretty amazed but I agree. My mind would have been blown instead. It’s amazing this little thing can path find and map out it’s surroundings. I’m wondering why it sometimes will go back to the start instead of spinning around celebrating its win. Maybe it’s just randomized.

@@luridftwgaming8983 It crashed or the wheels lost traction, probably by picking up some dust. This bot is really really light, and keeping its wheels from spinning is tough. It probably uses wheel input to tell where it actually moved, so once it slips, it loses its bearings.

@@luridftwgaming8983 Its because when it is spinning around, it is because it lost its 'footing.' It isn't celebrating, it is stuck. It only weighs a few grams, even a little bit of dust will make it spin out, that's why he's rolling the wheels with sticky tape between runs.

Electric Rune Games hahaha. Ok 👍, here I was thinking he added some personality to it.

is that true?

Yep, it spun and gave up

no no little robot mouse was happy

you’re wrong period

how do you know it was not a victory spin :P

He checked and readjusted the wheels but its more likely they readjusted the wheel so often they did it quickly out of efficiency rather than rushing/nervous

There's def an IMU in there and probably encoders on the wheels + other sensors for precise odometry. There's no way it's staying that lined up with the course just by counting on no slippage on the wheels.

Servos have been superseded by DC motors with accelerators/gyros now that the latter are miniaturized e.g. MPU6050. Dust on the wheels reducing traction is a big problem, hence the cleaning between each run.

it is self calibrating, so it adjusts its path from the walls. It never touches them but measures the distance.

shut up normie

the thing is.. this isnt even from 2016 when Begnizu Yakawen won the competition! this is 2011 bullshit.. 3.95 second win? garbage

+James Boyer Ah,thanks for pointing it out! :D 11:59 AM 4/22/2019 Happy Easter Monday! One minute away from PM! :O

Exactly. 😂

Me every time

This is actually the easiest part. Just keep a map of where you have been and use eg. the left hand rule: place the left hand on the wall and then just follow the path with your left hand always touching the wall thereby mapping all the walls. If you figure out, that in the area you have already explored there are no more uncharted areas, go back to the last position which has the possibility of leading into already uncharted territory and continue from there. Finding a way through this map to the goal actually is also not that hard. There are various algorithms to do that: find a way in a cellular arrangment, where path from one cell to one or more of the surrounding cell is blocked. (eg. Djikstra, eg. Lee algorithm) What impresses me is, that his algorithm actually takes the dynamics of the mouse into account (acceleration, deceleration) and that the mouse figured out that it can travel the diagonal at full speed. One of the hardest parts is actually to make sure, the mouse runs in a straight line at all times no matter if one of the wheels slips or not. Also it is hard to make it turn exactly the correct angle in order to be perfectly aligned for the next leg at full speed.

@@kallewirsch2263 So the harder part is actually the one that looks the easiest? interesting.

@@JonatasAdoM That is because within an algorithm you can control everything. While at the "interface" to the real world, this is not doable. You cannot control if the surface is perfectly level, if there are some dust particles on the floor, wheels have diameter tolerances, motors do not respond in exactly the same way to the voltage, optical sensors have to deal with stray light and so on and so on. You can imagine programming as "creating a perfect world". All things behave exactly as you designed them and how you programmed them. Of course there are programming errors, no doubt. Sometimes one started with the wrong idea and figures out that the idea does not work. That happens. No doubt about it. But still: A computer does EXACTLY what you tell him to do. If he doesn't, then the recipe you used was faulty, but there are no outside effects giving you troubles. Real physical world is different.

Isn't this the technology that self driving cars will use to remember paths? Or is it just google maps?

@@kallewirsch2263 That only works for simply connected mazes though. Are all the mazes closed in this comp? There are other algorithms for mazes that are not simply connected though, of course.

Indeed, KOJIMA San is respectable for his consistent efforts in making his mouse better and better!

or a misdated camera.

We all time traveled forward in time from 2011 into 2016 and then in 2019. In fact, we're all time travelling right now. On top of time travelling micromouse can do a maze in less than 4 seconds after second try.

its almost like a camera has an internal clock thats needed to calculate the time

Did you notice the fact that '2016' is part of the maze? ;) (the diagonal route is obviously intentionally put there by the designers of the maze to test for a mouse's ability to deal with that as well instead of only thinking in 'straight' blocks and lines)

You just watch a little robotic mouse run through a maze. That's what. Where you expecting something more? 😅

@@RedWolf777SG From reading other comments, apparently it's a competition of who has the best AI mouse robot?

@@falshion1837 actually is a fusion of computer science, physics and engineering. The really fast ones are not just aerodynamic the also have suction fans to hold them to the floor so they can decelerate and turn faster. It’s all about having the mouse that can determine how to get to the centre and back the quickest.

In this case the exit is not an island so the rule of right works, but maybe there is no rule prohibiting island exits.

"this changes my inquiry" Well then, good day to you, sir

It depends on the competition rules. For example, the IEEE 2020 rules stated, "The destination square will be positioned so that a wall-hugging mouse will NOT be able to find it."

@@christophertstone How can they contain a microcontroller, led, and battery in such small objects?

@@akj7 LEDs are tiny. micro controller can also be very small. guess is battery, motor, and sensors probably take up the majority of the actual real estate. even the battery doesn't have to last THAT long.

@@shnatko Can you recommand me some schematics or some kind of build project for this?

@@akj7 They can fit much more and in even smaller spaces. Quite easily too, it's just expensive to make. There are terabyte micro SD cards, and mechanical motors you can't see with you naked eyes. They just cost millions. These robots are actually quite large.

A piece of cheese

@@TheRealSAFN lmfao that was gold 👏

Actually, about 2000 USD AW shit I'm just joking. I don't know.

given that the maze is static, of standard dimensions, and can be investigated ahead of time, it's probably A*. but could be a D* variant as well.

TBH the hardware here is much more impressive than the software (well, the maze solving bit, the mapping out bit is not exactly trivial)

@@milanstevic8424 what, dfs too plain for you? :P

@@GeorgeTsiros I have nothing against dfs, but it is too plain and overly expensive for no particular reason. This is exactly why Dijkstra's algorithm (in its straightforward implementation) is mostly just a technical insight in today's engineering practices (likely A*) and is rarely used even in the most basic of games. And this kind of algorithm is pretty advanced compared to any dfs or bfs. These kinds of devices have very little processing power, and I'm guessing that the virtuosity of this competition lies in the software hacks, to massively speed them up, and not in the hardware. The most expensive and tricky parts of these algorithms are typically the solvers for minimum spanning trees and/or maintaining priority queues, and then having a flexible and reliable heuristics all of which is practically science in itself. Then again, I'm only speculating based on what little I know about all of this.

@@milanstevic8424 compared to the scale of time these devices operate on, any kind of sophisticated algorithm would not provide benefits. Consider even the fastest speed it moves nodes. 10 squares per second? Even on a 10MHz uC having 1 mil instructions available to toy with for one new square is luxury... and i'm pretty sure they're not using some decade old AVR like i'm used to. Bought a $10 dev board the other day... half a meg flash, 128k ram, 100 MHz and onboard DMA? Holy crap. Too bad i can't program it... too complicated and top complex. Anyway. Seriously though, my comment was mostly humorous. Of course they'd use a more sophisticated algorithm..., why not?

The rules did allow the mouse to store the path it explored. The mouse may think that there might be a better path than the one it took, and therefore, it did not take the same route back.
