Rubber bands - LEGO robot attachment that triggers with a motor
The robot attachment build in this tutorial gives an idea on how to release a rubber band at a specific moment using a motor. It's a simple, but yet powerful technique on using rubber bands.

Ultrasonic module for EV3 Kinesthetic and Memory Game
This module is meant to be used in EV3 Kinesthetic and Memory Game and is attached to the base of the robot. This module uses the ultrasonic sensor to detect the hands of the player. Attention must be paid to where the module is attached since it can be activated by accident if the player reaches for another module over this one.

PLF-block with two coefficients
EV3 PLF-block for LEGO front-wheel steered robots. The block has two relaxation coefficients – one for steering to the left and one for steering to the right. The aim is to make the robot follow a line smoothly when the color sensor is positioned closer to one of the wheels.
The block has the following parameters from left to right:
- Maximum angle – the maximum steering angle of the front wheels.
- Relaxation coefficient left – the relaxation coefficient regulates how sharply the robot responds to error, turning left. The default value is 1.
- Relaxation coefficient right – the relaxation coefficient regulates how sharply the robot responds to error, turning right. The default value is 1.
- Value on black – the value detected by the light sensor when it is on the line.
- Value on white – the value detected by the light sensor when it is outside the line.
