Create 2 – a preassembled robot platform, based off the company's Roomba®, that gives educators, students and developers firsthand robotic programming experience. iRobot also unveiled online resources, including 3D printable files for new parts, a faceplate drilling template, and educational projects and instructions.  Educational projects are designed to get users up and running quickly with their Create robot.

From beginner programmers to advanced robotics students, Create 2 allows for a variety of programming methods. Use it connected to your laptop, with a microcontroller or come up with your own solutions. You can also go beyond programming and build on to your robot, attaching sensors, electronics, grippers and other cool things.
