The Erwt is a simple programmable robot kit
Build a small two-wheeled robot and program it to do whatever you want! The Erwt is powered by 2 AA batteries and can communicate with a Mac or PC via USB. Learn about basic robotics, including motors, microcontrollers, sensors, and programming.
The Erwt comes as kit of parts (circuit boards, motors and electronics) which you can assemble into a complete robot.
Only simple tools are required, and basic soldering experience is helpful (it's easy to learn!). Assembly takes about 1 hour.
You will build and learn about the following features of the robot:
- DC motors and drive circuitry
- A bump sensor (to sense obstacles)
- Two light sensors
- Three line following sensors
- A beeper and LEDs
- USB interface circuitry
The Erwt can be connected to your Mac or PC via a USB cable allowing you to send it commands or download programs to run on its own.
Programming is simple in the Erwt environment with a simple language that provides a number of standard functions to control the robot.
The Erwt can also carry a pen, allowing you to write programs to draw complex patterns.
