Nice job, you don't see enough Lego robots on LMR these days.

I see the light sensor illuminated in the background. What's it used for? Detecting the distance from the board?

no, it is used to detect the end of the board and make the robot return to the beginning. It also has a touch sensor that detects the board and activates the eraser.

There'll always be a trade-off between power and speed. If you went commercial, you'd use a more powerful motor, which would support a higher gearbox ratio. This is still an excellent prototype.

finally it is finished, I've uploaded a new video where you can see how it works. We have added a light sensor to detect the end of the board and return to the beginning.

as you can see finally i've managed to add a photograph and a video of the robot. Here it doesn't work as it should, but I'll upload more videos when our robot is finished. Thanks for your patience, it's taken so long to update these image and video because we had some trouble during the building process of the robot, but finally we succeeded and by now it is almost finished (only some details are missing).

Gealexa, Please post pictures and video of your working robot. Or post a link to a website that has more info about your robot. Thanks. Kirk

Yes, It is supposed to clean a blackboard, or any kind of board that may be in a school, so it will work vertically. Today we have put together the two parts of the robot and it really looks very nice. I think it will work quite good, I hope on friday I can upload some pictures or small videos of it. That way you could see it really works vertically, at least for now.
