A fun to build robot that uses a microbit microcontroller board sold separately that kids can code or control using their smartphone via bluetooth. The kit is easy to assemble and no soldering is required. The included infrared and ultrasonic modules connect with the microbit, which enables the robot to follow a line, avoid or follow obstacles, and more. Other features include an onboard buzzer to produce sounds, an 18 rgb led ring for amazing colour effects, and a photocell to detect light intensity. Two large rgb lights on the front are used to indicate the robots direction as it travels. Once kids are competent using the microbit, they can create their own code to get the robot to use the microbits accelerometer, compass, and 5x5 led matrix. A 3.6v li-ion rechargeable battery is required for power microbit not included use xc4320 3.6v li-ion rechargeable battery also required use sb2298 included1 x smart robot shield base 1 x ultrasonic sensor module 1 x round led module 2 x wheels 1 x screwdriver 1 x usb cable 3 x 100mm jumper wires 4 x 150mm jumper wires 1 x omnidirectional wheel 4 x copper pillars 3 x acrylic mount boards screws and nuts
