When you have a whiteboard all is good until you need to erase it. This Whiteboard Erasing Robot will make quick work of it.
“The goal of this project was to create a robot which could erase written text on a whiteboard completely autonomously, i.e. no human interface. The processes involved in this project included devising a method for the robot to search a whiteboard for text, designing a way to physically move a robot to the text, and enabling a robot to erase the text.”
