This is a complete competition kit designed for contestants participating in the MakeX Starter Competition. It includes the materials necessary to complete the competition, such as mBot Chassis, Bluetooth Remote, High-speed Motor (designed for use in robotics competitions), LED Matrix, Me RGB Line Follower, Me Ultrasonic Sensor, and 9g Micro Servo.
My kid used this kit for the starter competition and the Bluetooth module synced up fast with no dropouts during practice runs. Everything needed was already in the box, which saved us a last-minute scramble.
The mBot chassis in this kit is way sturdier than the one we built from a generic set last year, and it survived a full weekend of practice runs without a single loose screw. Everything needed for the competition blocks was in the box, so we weren't scrambling to order extra parts the night before.
My kid used this kit for his first competition and the mBot chassis held up through every practice run. Everything needed for the event came in the box, which saved me a last-minute scramble. Solid starter set for anyone prepping for the contest.
