This kit gives kids a simple, fun, and customizable introduction to robotics that lets them build eight 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 a wireless Bluetooth connection. The ultrasonic sensor works on the same principle as sonar. It sends out sound waves, which bounce off objects. The sensor interprets the echoes returning to it, and from this detects objects in the path of the sensor. Using the app interface, you can program the robots you build to behave based on the feedback coming from the ultrasound sensor. A full-color, 64-page step-by-step illustrated manual helps kids assemble all of the models. 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. You can also add simple sounds to your programs. Requires a tablet or smartphone running iOS or Android.

Ages 8 and up.
