Click here to read LEGO Education NXT's little blurb about the Touch Sensor. It mentions that a hole for an axle has been provided (see picture). I'd also like to add something that wasn't mentioned... the old RCX touch sensor had the toggle running along one axis ONLY (for example, left to right or West to East). This new sensor has two axis to monitor - up/down and left/right. I think this will greatly increase the sensitivity of the sensor. Combine this with the axle hole and the touch sensor will be able to more quickly react to obstacles and touch input.
The ROBOTMAK3RS continued their celebration of the 25th Anniversary of MINDSTORMS through these Fall and Winter remix projects. Each ROBOTMAK3R was tasked with selecting one LEGO set of their choice and combining it with a MINDSTORMS set. Below are the five amazing models they came up with. Braill3 by Jerry Nicholls Braill3 is an EV3-based LEGO Braille bricks reader. This robot uses its fingertip, made from three touch switches, to read messages written using the LEGO Braille bricks and will speak out what it detected. If it sees a simple maths problem it will attempt to solve it and give the answer as well. To learn more about the process of creating this machine, read Jerry's blog . Braill3 can be viewed here . Set Review: The Braille Bricks set is well thought out. The ratios of the letters is suitable for general use and the addition of some punctuation and arithmetic operators is excellent. There is a card showing what bricks there are and their quantities, but no form of sort
