Version 1.3 of this popular kit now uses a removable ultrasonic sensor, that uses the same connector as used on the Minibit and BitBot XL. This allows the use of alternative addons, sich as the new BitFace, 5x5 FireLed Matrix and OLED. The Robobit Makecode package supports all versions of the Robobit Buggy. This little buggy can be assembled very quickly using only a screwdriver. No soldering is required Mk3 changes from Mk2: * Integrated line following sensors * Integrated ultrasonic distance sensor with new connector * Integrated pen holder mounted at the axis of rotation * Integrated 8 element FireLed bar with “auto scanner” software support * Motors fitted on top to make it more compact * Screwdriver and wrench tools included
