LEGO 9843-1 Touch Sensor is a Mindstorms NXT set released in 2006, containing 1 piece. It includes a Touch Sensor accessory designed for use with the LEGO MINDSTORMS NXT system and requires set 8527 or 8547 for operation. The sensor allows NXT models to detect physical contact or button presses as part of programmed actions. The same sensor design was later reused with the Mindstorms EV3 platform, including set 31313.

A new and sealed Touch Sensor is currently valued at around $32, with annual growth of approximately 4%, which is higher than other NXT sets. The average used price is $4 for those in good overall condition. Based on current trends, this set could be valued near $34 within the next year. The set was available for 100 months, from October 2007 to February 2016.
Touch Sensor is a rare LEGO set. We have not seen set 9843-1 available in good/new condition online or in retail stores for over 2 years. Given how hard it is to find, the estimated value in new condition of $32.36 may not reflect its true collectible worth.

“The Touch Sensor gives your robot a sense of touch. The Touch Sensor detects when it is being pressed by something and when it is released again. You can use the Touch Sensor to make your robot pick up things: a robotic arm equipped with a Touch Sensor lets the robot know... More whether or not there is something in its arm to grab.”
