Get your child excited about robotics with this fun kit that allows kids to learn the basics and build eight machines controlled by programs and sensors. Each of the models uses continuous tracks to move. Kids will learn how to code programs using an easy app on a tablet or smartphone. They will also learn how an ultrasonic sensor works, and by using the app interface, will program robots to behave based on ultrasound sensor feedback. The step-by-step manual includes easy-to-follow instructions that teach your child how to build eight different models and understand robotics in the real world. Warning: Choking hazard. Small parts.
