Tiddlybot is an easy-to-build robot that can connect to any smartphone, tablet or PC that supports HTML. Run it as a remote controlled toy, or program it using a custom Blockly interface.
The robot features two servos, line sensors and multicolored LEDs. There’s even a spot to fit a marker, so your robot can draw.
The basic edition costs just $48 on Shopstarter, but you’ll need to supply your own Rasberry Pi. For $115, you can preorder the Tiddly To Go Ultra, which includes the Pi, a camera, a WiFi dongle, and a LiPo battery charger.
