Please look at the description.

I’m sorry but I no longer have the instructions on how to build it.

Sorry, I don’t have an EV3 so I can’t create code for it. You can look at the MBasic code and adapt it.

The place I was consulting at had them. Originally they connected via some posts with magnets. I designed and 3D printed new connectors. The files might be on Thingiverse under TechTown.

You cannot adjust the sensitivity of the sensor. You can move slower if you want.

Sorry no.

Sorry, I don’t have a Spike. I don’t know if the people that developed EV3Basic will do a SpikeBasic. But the logic is simple: 1) Move forward until a wall is detected. 2) Take a distance measurement from both the left and right sides. 3) Turn in the direction of the longest distance. 4) Go to step 1. Of course you need to also detect the end of the maze.

See the description, links to the code are there.

Can you program the maze robot? I am 8 year old. Can you make a video about how to program the maze robot. Thank you 🙏

And can you tell me the code e

@@VuTran-fc2rg I’m very sorry but I don’t have access to a EV3 robot anymore.

I don't remember exactly but just followed a build of a two motor with a caster wheel up front. I did add the "bumper" around the robot to prevent the wires from catching.

As stated in the description, the program requires SmallBasic and EV3Basic. I've added the links to both programs on GitHub.

El robot usa una versión de Scratch de la compañía MakeBlock (www.makeblock.com/). No se si todavía venden ese modelo.

Sorry I don’t have access to an EV3 robot any more. I haven’t checked if the EV3 supports Python.

Thanks!

Which previous model? You should be able to adapt the software to any other model.

@@AramPerez You need an additional distance sensor (pivotting or side-mounted) as turns are often inaccurate. Is there sth. like a gyro sensor to improve this?

@@wolfgangr.3268 Even that won't necessarily help unless you use an expensive gyro. See my other video of an Lego EV3 solving a similar maze that does use a gyro for turning: kzbin.info/www/bejne/iKCahWanZpmoers. I used a different algorithm to solve the maze and I used the color sensor to detect the end of the maze.

Sorry I don’t have access to any EV3 robots. You should be able to look at the BASIC code and convert it to the Lego software.

It would be possible but I no longer have access to any EV3 robots. ☹️

Thanks!

It’s just plain black electrical tape. I haven’t had any problems with it being too shiny.

See the description for a link to the code.

Thanks, glad you liked it!

Look in the description.

Sorry, as I stated in other replies, I don’t have the instructions.

tony, thanks!

I’m not sure what you mean by “its structure diagram”.

Check the description, the link to the software is there.

Link to the code is in the description.

EGY Makers, sorry, I don’t have the Arduino code. From looking at the mBlock code you should be able to write the Arduino code.

@@AramPerez mblock code not open please share it again

Hi Michal, the clips are 3D printed. I’ll try to find the models and post a link here. I’m really busy this coming week but will look for the models the week after.

@@AramPerez thank you. I will be waiting for that.

@@AramPerez Hello. I was also interested in your modular wall system. Could you also send me the models? Thank you!

Hi!!! Do you help me?

el pato loco, si, esa es otra manera de resolver el “maze”.

Please if u get program of it plz send me

do you have the code in the LEGO MINDSTORMS Education EV3

Hi Dave, I've uploaded the code to github.com/aramperez/EV3-Maze-Solver.git. Just a reminder, you will need EV3Basic.

Can you show us how you build that on mblock ?
