Insights

Retired Mindstorms accessory Tilt Sensor (set 9584) was an Education-line part whose appeal is mainly to NXT/EV3 builders, and sealed examples have grown scarcer; limited standalone display value and successor robotics platforms have kept broader collector upside constrained.

Set Facts

The tilt sensor for the WeDo Construction Set can detect six different positions: Tilt This Way, Tilt That Way, Tilt Up, Tilt Down, No Tilt, and Any Tilt.
The WeDo Software automatically detects the tilt sensor when it is connected to the LEGO USB hub.

About Education Mindstorms

These are the LEGO Education versions of Mindstorms, sold to schools, along with the extra parts made for classroom use. The first ones paired the RCX brick with ROBOLAB, programming software built with Tufts University and National Instruments, in team challenge sets. Later sets followed each new brick, the NXT and then the EV3, whose Education Core Set of 2013 came in a storage box with a rechargeable battery.

Mindstorms consists of 25 sets that ran from 1999 to 2016. As of today, 45544 Education EV3 Core Set is the most valuable Mindstorms set with an estimated new/factory sealed value of $546.

The tilt sensor designed for the WeDo Construction Set detects changes within six different positions: Tilt This Way, Tilt That Way, Tilt Up, Tilt Down, No Tilt and Any Tilt. The tilt sensor is automatically detected by the WeDo Software when connected to the LEGO USB hub.
