Robot à base d’arduino

Mon père et moi avons construit un robot.

robot1

robot2

Nous l’avons fabriqué avec un rond de bois (contreplaqué) de 7,2cm de rayon, , une Arduino Duemilanove, trois switches, une plaque d’essai, deux capteur infrarouge, 2 servo moteurs, une pochette de stylo BIC , des fils électriques, une pile 9V, un porte pile 9V (avec adaptateur pour Arduino). La premier version du robot possédait trois capteur de contacte (switches à l’avant).

La nouvelle version utilise en plus deux capteur à infrarouge  (l’un à l’avant, l’autre à l’arrière).capteur ir

Comme les servo moteurs semblent consommer beaucoup d’énergie, nous avons décidé d’utiliser une alimentation séparée pour ces derniers, afin de ne pas vider la pile alimentant l’Arduino trop vite.

La suite très bientôt …

I’m thinking about a small project, allowing videoprojection of educational content in a classroom.

All based on a beagleboard, a pico projector such as the one from TI, or a mini projector (weighing less than 900g), and an low cost interactive whiteboard based on a wiimote or IR camera.

The beast would be able, in a small volume (20 * 20 * 5cm max, but 10 * 10 * 4 if the pico is satisfactory) and low weight (<1 kg), with commonly used open source software (I’m targeting math teachers …) and would have multimedia capabilities added to it when adding speakers (for languages and literature teachers). The price must be around 500 euro.

The project (software and hardware) is obviously under a free license and will consist primarily in a compilation of applications that run on ARM architecture, as well as the adaptation of code to manage the Wiimote / IR camera.

This is a rough idea for now. The steps are:

* Get a beagleboard
* Get a pico / mini projector (the tests will be done with a massive standard projector)
* Test a solution with wiimote (I have a wiimote or rather a copy of wiimote)
* Test a solution without wiimote (some electronics, I may need a little help ;) ) with IR camera or webcam.

If you are interested in such a project, please help out, with either technical or ideas.

I’m currently developping a software to draw and animate 3D surfaces representing two-variables functions, named Ying.

Beta version is downloadable here : yingsoft.wordpress.com

The BeagleBoard is an ultra-low cost, high performance, low power OMAP3 based platform designed by BeagleBoard.org community members.

In clear, it’s a very small motheboard with ARM processor, video with 3D capabilities, USB, and more … It’s power comsumption is around 1 W !

I’m thinking about getting one …

Hello !

Welcome on my blog. It’s about our experiments in electronics and informatics.
