[@alasuisi]

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.

[@jonathanyang1423]

​@@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.

[@alasuisi]

@@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

[@jonathanyang1423]

@@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).

At first I wasn't sure what the point was cuz the speed of the first run of a robot in a maze will always be relatively random. Then I started realizing that whenever it retraced any straightaways it had already gone through, it went faster cuz it knew it could go faster. Turned out this was more of a mapping precision coding type of competition. Pretty awesome to watch.

The mechanical precision of this mouse is outstanding. The wheels alignment must have been absolutely spot on as well as the servos calibration.

[@meh6513]

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

[@r7calvin]

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.

[@adventtrooper]

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.

[@bobsnabby2298]

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

[@JonatasAdoM]

It mapped almost the whole maze in the first run. Impressive.

[@kallewirsch2263]

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.

[@JonatasAdoM]

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

[@kallewirsch2263]

@@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.

[@eSSentialplaysYT]

As a former software engineer, I am curious why they don't run a 'mapping' run by using the Rule of Rights when navigating a maze. That is, you always follow the right-hand wall, as it will always lead to the goal; and then continue mapping the rest of the perimeter by continuing past the goal still applying the Rule of RIghts, then map to the inner section(s). I am imagining the mapping process would be slower, hence why they use the methods they do? Fascinating to see how it maps, even though it feels 'random', there is clearly a process for data collection, and an algorithm for mapping routes as new wall data is mapped and an 'as many straight lines as possible' final path determination. EDIT: I just realized that the goal could be a 'floating' space not connected to any other wall(s). This changes my inquiry.

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

@@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.

[@GeorgeTsiros]

@@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?

知識もってませんけどちょこちょこ動くネズミかわいい、あの５分頃の斜め移動すごい！

[@BlackWolf18C]

The interesting part is that it mapped the maze and learned. At first I thought it was just doing a simple if, than, else loop to navigate, but it found the optimal route and applied it. Once it knew the best way to go, it was little surprise that it could do it that way with scary speed and precision. Impressive, for sure. The implications of actively learning microrobotics are kind of mind boggling. If that little mouse communicated with a little drone, it could find the optimal route through the maze before it even moved at all.

[@masterstaskin]

Exactly. It is what the mouse has to do in a first run - learn. You may check out the rules of the contest at www.micromouseonline.com . If the mouse knows the maze in advance that would be algorythm so called "wave propagation" Lee's algo maze route finder (which was actually computed basis known facts abt maze and used on a final speed run in this video). I was surprized that mouse seems to be using Moore neighborhood (i.e. learning 8 directions) because running diagonal at the end. Programming mouse behaviour is actually not a big problem, almost same as tracing pc cards

Probably not an AI at that level, it's more likely to be a pathfinding algorithm and some optimization on top

The first try takes in full lenght about 4 min (60 sec to find the goal and another 3 min for mapping). Well, and if you got the map just use the dijkstra algorithm to get the shortest way to the goal and finish... But i don't know why they let him end the mapping, instead of end if the mouse reach the goal.

[@marcianpetrescu]

so, let me know if I understood this corect. First, the electronic mouse is crusing through the maze in order to analize the path of the maze and doing this is "learning" the architecture of the maze... after that the idea is to complete the maze as quick as possible using what he was "learning" from previous atempts... ?

[@worldcomicsreview354]

Could you build one with 3 lasers coming out straight ahead, and at 45 degree angles, on the front? Then it could detect the small dead end areas without actually going in them. Some sort of colour detection could also let it know if it's facing a clear run to the white area, so it can run straight in.

[@bishoptakesknight]

Apperently the mouse weighs less than 5 grams, so thats a good question. Could you add these features without adding weight, or very little, as too not break the rules of the competition, or interfere with manuverability.
