We have seen plenty of cool robot kits from RobotGeek in the past. The RobotGeek Whegly is an Arduino Wheg robot that can negotiate rough terrain better than average wheeled robots. It can go from rolling to climbing quickly. This kit comes with 1x RobotGeek Geekduino, 4x RobotGeek continuous rotation servos, and rigid construction. It is powered by a 2200mAh battery that lasts up to 2 hours.
You get a infrared gamepad for manual control. You can add sensors and additional components to enhance the robot.
