If you have to do a lot of drawing on a whiteboard, you also have to clean it. Why not have a robot do this instead? That’s the idea behind Wipy, an Arduino Uno-based robot that uses magnets to stick to the board, along with grippy wheels and motors to power across your scribbles.

Wipy employs an array of IR sensors that enable it to act as a line follower, plus a time-of-flight (ToF) sensor to detect your hand on the board. While one might assume this sensing arrangement would prevent it from erasing your work-in-progress, it annoyingly allows it to start erasing immediately when you start drawing. At least it has a cute LED face!

The project was conceived by Lasath Siriwardena, Simon Lut and Tim Stark as part of the ITECH Computational Design and Digital Fabrication seminar. Additional information, including code and files, are available in the team’s write-up here.

Did you ever get tired of cleaning the whiteboard? Have you ever wondered how much your life would improve if a robot could do this for you? You now have the chance to make this a reality with Wipy: the overly motivated whiteboard cleaner. Wipy will properly clean your embarrassingly bad drawings, and it will even do it with a cute smile. You don’t even need to activate it! It will just clean the board when you least expect it… Uhhh…*cough cough*…we, of course, mean: when you need it most!

– Our future friend will be able to stick to the board using magnets and is able to move through space using grippy wheels.

– It will be able to follow a line and erase it using a line-following sensor and a sponge.

– Wipy has the ability to measure the distance to your hand using a time-of-flight sensor.

– We will give Wipy a cute personality using a small OLED screen.
