The Root is an educational robot developed by the Wyss Lab at Harvard University and exhibited at CES. The code-teaching robot can show kids how to code with spirograph-like drawings.
It has a whiteboard eraser built into the bottom and a USB-C port on top. The port is intended for "modular accessories that plug directly into the top of the little Roomba-like robot." These accessories will become available later on this year and currently include a bulldozer add-on and a LEGO board-esque 'building block tray.' Pre-ording The Root now will also get you markers and a foldout whiteboard. The robot can magnetically latch onto a real whiteboard and begin drawing too, meaning it can draw upside down and sideways.
