It requires no assembly or tools - simply insert your :bit and a 18650 Lithium Ion battery (not included) to start driving. The improved Cutebot Pro integrates a lithium battery box and is compatible with all 18650-sized batteries, eliminating the necessity for a separate lithium battery expansion pack. The Cutebot Pro is a rear-drive smart car driven by dual high-speed motors, which can zip around your floor. It has an ultrasonic distance sensor to avoid colliding with walls, two RGB LED headlights and two underlights, two line-tracking light sensors, an active buzzer to make beeps and tones, and various headers for attaching additional servos and sensors. Note: Does not include micro:bit or 18650 Battery. This is just the Cutebot kit by itself!
