JIMU BuilderBots Kit
The BuilderBots Kit is a great introduction to STEM learning. It includes everything you need to build GrabberBot, DigBot, or use your imagination to invent your own. It includes treads to move with, and an infrared sensor to detect objects to pick up or move around them. It also includes an LED light that lets you program emotions and play in the dark.
