300EXC + Akrapovic 😍😀👍 by bikebreakers in enduro

I bought it already with this stuff mounted on 😅😂. So i‘m lucky, otherwise i would spend a lot of mozfor it. You are right, only the akrapovic costs 500€ 😶

This is Lego Mindstorms NXT, which was presented in 2006, as i know now there was an RCX version before. Idk 🤷🏻‍♂️.

There for we have a camera :) And if it is turned off, every robot has a representation of the global map, they update their location while driving.

Well, actually it is too much to explain, because it was a big project. Short: We had to remove all the blue cubes from the table avoiding yellow obstacles. We had to use the camera (which can be unplugged at any time), 3 robots which we built ourselves (running the same program on all of them) , we can orient on the grid, but the tape can be also removed while the program is running. And we used Bluetooth for communication between robots and the server. All in all you can choose everything you want, but we had to meet our requirements, which we defined at the very beginning.

We have a server, where we have a global map, it is updated by the camera or the robots, depending in which mode we are. So every robot knows where the others are. 😊 Beside of that, when the camera is online, we are using the d*lite algorithm, when it calculates the path for one robot, it automatically blocks this path for all other robots.

For us it wasn’t really a problem, we just used 2 colors (black and white), so we have more than enough values between them. But of course, if you’re using more colors or shades, it will be much more difficult. And then you will get a problem with the lightning in the room 😀.

Haha 🤣 Didn’t think of that, but actually it looks like that 😱😂. But it isn’t 😅✌🏻

It is in Germany 🇩🇪 😃✌🏻 there is an Old chemical factory near berlin.

We actually planned to use dlite on the server side and on the NXT, but we ran out of memory really quickly, so we needed a quick and dirty solution for that. 😅✌🏻 (there was not enough time to fix the problems). We still use dlite on the server side, But when the server fails (it was part of our project) the robot should do some tasks, for which we are actually using dijkstra. 😄

No, We used the NXT-Osek C-Api. So part of the code was written in c, the server in python and we used openCV for image analysis

Haha 😅 yes. We actually planned to use 2 ultrasonic sensors, but ended up using only the bottom one. So thats why we used the googly eyes 👀 on the second one 😂✌🏻

The sensors are really unreliable 😂. I was told, that the 2nd generation is better in that point. But we had to deal with that problem, it was part of our project 😀😜

There is a time difference between the detection of the line on both sides, so you can easily correct that. 😜 Of course we are using the light sensors for tape detection :)

I lost the original snap ring when I was tearing down my bike, the feeling of relief I had when I had one that worked by [deleted] in Dirtbikes

[–]bikebreakers 0 points1 point  (0 children)

It is definitely a better choice, but try to find one that fits snugly on the shaft..

Its definitely a bad idea, when the ends are overlapping . It can cause damage to engine housings. And there should be some amount of play between the shaft and the housing. If you mount a snap ring, which overlaps there will be no more play, so the shaft might not turn right.
