Robotics is a vast, thrilling, and sometimes overwhelming interdisciplinary field involving physics, engineering, and computer science. This kit gives kids a simple, fun, and customizable introduction to robotics that lets them build 8 motorized machines controlled by programs and an ultrasound sensor. Kids code the programs using an easy, visual programming app on a tablet or smartphone, which connects to the robot models via wireless Bluetooth(R) connection. A full-color, 64-page step-by-step illustrated manual helps kids assemble all the models and teaches them about robotic in the real world. The visual programming language allows you to command the robots' motors to move at different times, different power levels, in different directions, and in response to the data from the sensor. The kit includes 194 building pieces. Requires a tablet or smartphone running iOS (IPhone 4S or later, i Pad 3 or later, iPod 5 or later) or Android (Android 4.3 or later on a device with Bluetooth 4.0 support). Ages 8 and up.
