"Build and program robots that can walk, crawl, roll, and sense objects in their path with the Robotics Smart Machines set. There are eight motorized machines to construct, from a beetle to a bipedal droid and even a spy bot. Each robot uses an ultrasonic sensor to interact with its surroundings. The kit comes with a free coding app that can be downloaded onto your computer or mobile device so you can wirelessly connect and control your robots. Robotics: Smart Machines is fun and easy to use thanks to a 64-page illustrated manual that provides step-by-step instructions.\r\n\r\nRequires a tablet or smartphone running iOS (iPhone 4S or later, iPad 3 or later, iPod 5 or later) or Android (Android 4.3 or later on a device with Bluetooth 4.0 support).\r\n\r\nhttps://www.youtube.com/watch?v=nWxkCGyjEEA"
