Programs

- Follow black line using two light sensors.

- download the whole program of the robot in NXT-G.

- download and import the whole Menu myBlock. It might require you to modify it so that it fits to your needs. Any comments on modifications you have made are really welcome.

- Download the whole calculator, ready for use.

Program for displaying the value of the sensor on the screen

- download the source of a program that tells the color the robot is seeing.

- download the NXT-G source code of the program.

- Download ready to use source code of the NXT-G program solving the Video Call, Blue Quilting, Woodworking missions.

Program, that makes your robot move in square.

Example of making turn using the steering option of the move block

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.
