This is a minifigures' dance pad. It spins and shines lights everywhere. Only one motor. I like how Wyldstyle is dancing with Emmet because they end up together at the end. I used the Melting Room for the dance pad, and my color sensor for the disco lights.

VI3WBOT is a mobile robot which is equiped by a camera (a mindsensors NXTCam V4), a color sensor, a touch sensor and a gyro sensor. Using the NXTCam V4, it can reconize and catch a yellow ball of specific size, thanks to its colour and its form. In my first programm, I just made a recognition using colour information, but the robot also detected other yellow objects (for example the bottle of the video)! The NXTCam V4 delineates a detected object by a bounding box and outputs the coordinates of the corners (x and y). With this information, one can calculate the area and the rough form of the object. In my program, I test the area and the shape of all the yellow objects, and the robot always chooses the good object (or nothing, if no object is a yellow ball ). The NXTCam V4 is a complex sensor, so it outputs a lot of values per second, and these values vary very quickly. To solve this problem, I created a new filter that smooths the data. It works very well! Without this "DataFilter" mini-program, VI3WBOT cannot work properly. VI3WBOT cannot work properly either if the ambiant light is too poor (for example, a yellow ball is acquired as if it were green in the dark). So when the program starts, the screen displays the minimum luminosity that it required as well as the current ambiant light. I will show my video very soon!!! But I have difficulties to upload it. In the future, I will use my NXTCamV4 to make new more complex robots, like humanoïds and autonomous animals, or other "deadly" creatures...Coming very soon! PS: Please comment and rate my older creations !

TO3 Tank II is a slight upgrade of TO3 Tank. It has several changes, which I will tell about later. Sorry, I had to clean my room, so no new course. However, I will go into detail of the changes. (For a better explanation, go to TO3 Tank's original post.)

PRINT3R is my first printer robot and(I think) is pretty cool. PRINT3R uses 2 large motors and 1 medium motor to draw anything you program it to. It draws on a five inch wide piece of paper. I used an arm to move the pen because I wanted to use something not many of the other printers on the community used. A program will be coming but feel free to make your own while you are waiting. Please rate, fav and follow. Visit Additional Information below for more info.

This is a steady and fast walking base for humanoids. Besides walking, I also programed it to dance. See more info and some videos in the additional info.
