Scratch (Word Blocks) program to align to a line with color sensors from LEGO Education SPIKE Prime
This program is developed with LEGO Education SPIKE App Word Blocks and is used to make the Luly, small LEGO Education SPIKE Prime competition robot with 3D building instructions align to a line with two color sensor. It's a mechanism we've used with EV3, NXT and now SPIKE.

How to build a LEGO Mindstorms robot that does not fall from the table
In this episode we are showing the great similiarity between the sensors in NXT Mindstorms. We are solving a common problem - How to make a robot that do not fall from the table. We are using the Ultrasonic sensor, Light Sensor and Touch Sensor to solve the same problem, but with three different sensors.
