Floor cleaner

For long I had nothing new to show here until I built this little robot. It takes only 2h to came up with the construction but gives much more fun in return. Why don't you try it?


Two games - Pong and Driver

Two very simple games for the NXT-brick's LCD screen. No additional components required. No building. Just download the program and play!


Remote controlled cannon

Simple robot utilizing both of my sensors - accelerometer and bargraph. The turret aims according to position of the remote and the remaining amount of bullets is displayed on the bargraph. Finally those sensors were put into some use!


Flyerbot - robot giving flyers away

Project carried out during my month internship in the Creative Space company. This robot hands out flyers in the most attractive way I could think of. Fairly complex project which turned out to be a huge success.


Bargraph - control 10 LEDs from your program

This is a very simple electronic circuit that allows you to control 8 LEDs from your program and 2 other LEDs manually. It's particulary usefull when LCD is not enough.


Edge Avoider - robot that avoids edges of a table or a black line

What can I do having half a day off? Of course - build a new robot! This ultra-simple one drives in random direction on a table and tries to avoid falling off the edge. It can easily be adjusted so that it stays inside an area surrounded by black tape. See what you can build and program in just an hour!


Accelerometer & Magnetometer - custom made sensor

I proudly present to you my custom made accelerometer & magnetometer. The sensor was build using LSM303DLH chip and adopted to use with Lego. Now it is possible to measure robot's exact position in space and to steer very accurately. The total cost was 3 times lower than any comercially available sensor for Lego. It was definetely worth building. Read more to see examples of use and detailed description.


Tape reader - Sequential access memory

This robot reads binary data from a tape that is moving very quickly underneath it. Then it presents information in a form of text on the screen or music from speakers. Read more to see how it plays Beethoven!


My own custom sound sensor

I didn't want to spend money on original sound sensor from Lego, so I've built my own. Just like that! It's a simple amplifier with a microphone. I'll definetely build a robot controlled by clapping.

Sound Sensor

Micromouse - robot solving a maze

This agile robot solves a previously unknown maze trying to find the shortest route. To seek path and to navigate it uses rotating color sensor only. Time-consuming project but it gives incredible satisfaction!


Robot that climbs up a hanging rope

Very simple robot driving up a rope. See a video of it climbing to the second floor in under a minute!


Linefollower - The Second One

Improved linefollower following only black line with intersections using just ONE light sensor! Fast design and very good steering algorithm.


My very first linefollower. It was build with only one color sensor, but it follows tri-color line. Very simple project for the beginners.

Furthermore, I started posting videos (more like slideshows) with detailed building instructions for my robots. Watch slowly!


Flamethrower on tracks! This original robot searches for potential targets and attacks them over-half-meter flames. No one has ever tried this! It's a must to see!


3-D Scanner

This 3D scanner lets you save a digital model of any item to recreate it later on a computer. You will be surprised how accurate model you can get. Very simple construction makes it possible for anyone to build a similar scanner!

New domain + new server

I decided to move my site to LegoRobot.pl. Shorter domain is easier to remember and there is no annoying ads in random places. I hope you memorize new site name and visit often!

A light-controlled robot finally done - great success

It took me almost a month to build, programm and test this robot. Now it's finally finished! It can dynamically search and follow light from a flashlight or a bulb, and not only in the total darkness! You just must see this unique construction.

A real-steering car

Next project is a car model with turning front wheels. See it here.

Another project added - A Crane

I've just added another project. This time it's a crane model that has rotating base, extendable arm and a lifter. Watch here.

My website is finally done!

After weeks spent on the look and content of this website I can finally present it to You. This site presents every single project I have ever made or tried to make using LEGO MINDSRORMS® NXT 2.0 kit. Now it contains two of them. Every single project includes a brief description, videos and photos (some are 3-D). Soon I'll add next finished robots.

I'm still working on step-by-step videos presenting the construction of my robots so that you can build them yourself.
