>>So you can drive it any shaped path? That looks great Yes. That's possible. If you have the mathematical function. >>P.S.Please credit the wheels creator. Yes. You are right! I will do :-) But it is not this creation. The shown wheels are more stable. I used a modificated version. Thanks to Eric Steenstra for the wheel creation. I know, that he developed it with another one but I haven't the name.

Hi! I will show you two photos of my new project: The EV3MathBuggy with the following functions: controlled via iPad or iPhone (Using the Gyroscope). Integrated web service. selecting some defaults or typing any kind of mathematical functions. The EV3 MathBot will drive the function. Using mecanum wheels. A video is coming soon. Andreas

I programmed the eyes with LeJOS in Java. There is a method for the Ultrasonic sensor for switching the lights on or off. See the line 40 and 57 in the following code: https://github.com/abaumgart/HalloweenEyes/blob/master/src/halloween/Eye.java Andreas

Time, for shocking some people ;-)

Hey @AkiyamaWataru: Thank you! Yes! I also read it :-) Very funny to see my own project this website.

Thanks and yes! I think it is very meditative ;-) Also relaxing to program the pattern :-)

Thank you ! :-) Build and try it Thank you !

Hi! The Billund table in action! Enjoy :-)

Thanks :-)

The programming is not the problem. It took even longer to get the result or changing the parameters for a creative design. I made a video the last days. That took a terrible long time. It will be published on YT the next days. But here is a picture of my "Billund table". The shown spiral needs nearly 15 minutes to be finished. But you can't hear nearly nothing. No motor and no steel ball. If you hear the ball, it sounds like foot steps in the snow :-)

good night :-)

:-) Thanks! Build Cr3amRoulette and enjoy! We are looking forward to see your pictures ;-)

Thanks! Yes. But I did the first test on myself (without a cam) ;-)

Hi ! This is the introduction to my RobotRemix Cr3amRoulette (CR), which was created from the LEGO MINDSTORMS 31313 and Technic Airplane Jet 42066 sets. CR is pure fun and you will wish but one thing during this game: "Please, not me!" I had the idea when I saw a video of the game "PieFace" on YT. I thought: I have to do this with LEGO MINDSTORMS! The game’s goal is simple: belong with those who do not get cream catapulted into their faces. You start the game by cocking the catapult and pressing Enter on the EV3 Brick. The catapult is now locked. Then, you place a nice large portion of cream on the catapult. Then, CR generates a random number at which the catapult triggers. This number corresponds with a certain degree of engine rotation. The loudmouth starts. S/he pushes the touch button and rolls his/her number of moves between 1 and 6. Then, s/he has to place his face in the frame and turn the wheels slowly in his/her direction with both hands. 50 degrees correspond with a turn. The end of each 50 degree rotation is announced with a tone. For example, if the player rolls a 5, s/he has to turn the wheels by 50 degrees 5 times. CR counts the turns and compares this with its previously generated random number. When the number is reached, the catapult releases! If not, it’s the next player’s turn. S/he, too, rolls the number of his moves by pushing the touch button, places his/her head in the frame, and turns the wheels according to the moves. This goes on and on. But believe me: It’s someone’s turn eventually and the catapult will strike! CR is relatively easy to assemble. During the design phase, the biggest challenge was a construction that was stable and compact at the same time. The parts of the 42066 set are quite suitable for this purpose. You can download the LDD-File and the program from my website: www.andreasbaumgart.com

Hi ! Thanks a lot ! Yes. I have this plans :-) Andreas Thank you :-)

Thanks :-)

Hi! Here is a tiny status update from the LEGO Mindstorms sand table :-)

Hello, actually i am working on an small robot, who is able to climb about obstacles.This is the current version.

I want to programm different mathematical Patterns. :-) Thanks! My brain worked a more time on this idea as you can see on the video ? But yes. The mechanical result is even simpler.

The last nights were short but here is the result: The second prototype for a sand table. A sand sculpture based on #LEGO #MindstormsI will keep you up-to-date on the further development :-)#Mindstormsmagic

Hello, i want to show you a small idea for a scissor mechanism. Andreas

Hi ! I haven't made a follow-up video. Maybe it is an idea for next the next time. I have also begun to realize its designs with LEGO. I've released a few in my YoutTube channel: Andreas

A construction for controlling linear and rotary movements. I saw it in a mechanical engineering video by Nguyen Duc Thang ( https://youtu.be/gU0wqocH7tQ ) and realised it with LEGO.

... just for fun and a little bit java programming

Thank you. The elaboration of the technique took a long time. The result is quit simple We use glue for wallpapers. This has the advantage that we can mix the mixture ourselves. So we have influence on the consistency. The adhesive is stored in syringes. The piston is moved by means of minimum torque motors. This presses the adhesive into the lines. You can see it here (https://youtu.be/BHBlOzzV-Qk?t=2m6s) At the beginning of the foldingprocess, small tubes are pressed against the paper to push it in the desired direction. They are mounted in such a way that they also apply the adhesive in the correct place. This takes a total of 3 syringe units. These are completely identical in structure. (Https://youtu.be/BHBlOzzV-Qk?t=2m17s) You can also see the sensors that react when the syringe is empty. Cleaning is not a problem with the adhesive used: Allow to dry and break. As far as the lines are concerned, we just push a silver wire through. The folding and gluing unit is mechanically very complex. Likewise, it is complex to care for them. :-)
