2x Sensor Proportional Line Follower

This EV3 programming tutorial will teach you how to make a 2x Sensor Proportional Line Follower in EV3-G. This is a combination of two different line followers that I have previously made. This line follower preforms well in FIRST Lego League (FLL) Competition. 142 total views, no views today    Send article as PDF

Using Port Wiring for Sensors & Motors

The EV3 brick can communicate with up to 4 motors and 4 sensors via its ports. Motor ports are named A-B-C-D, while sensor ports and numbered by 1-2-3-4. Most often you have decided which motor to operate for moving the robot or pushing and arm that is connected to a motor. In FLL robots I […]

Simple Proportional Line Following Code

What Does Proportional Mean? A proportional control system measures the error (the difference between the system setpoint and the current state) in a system and then either increases or decreases the system output by enough to minimize the error. Proportional refers to the system’s ability to make small changes for small errors and large changes […]

Driving Straight with Gyroscope & PID

Download Code: DrivingStraightWithGyroscopePID.ev3 A proportional–integral–derivative controller (PID controller) is a control loop feedback mechanism. As the name suggests, PID algorithm consists of three basic coefficients: proportional, integral and derivative which are varied to get optimal response. In practical terms it automatically applies accurate and responsive correction to a control function. An everyday example is the cruise control on a road […]

Infrared Sensor

You can use the Infrared Sensor to measure the distance to an object, or the distance and direction to the remote. (The Infrared Sensor is not included in the Education Edition.) You can often substitute the Ultrasonic Sensor (using one of the Distance modes) for the Infrared Sensor to measure distance. Proximity Mode Use Proximity […]

Motor Rotation Sensor

Each EV3 motor has a built-in Motor Rotation Sensor that measures how far the motor has turned in degrees or rotations. You can use this sensor to control how far the robot moves, and to read a motor’s current Power parameter, which can be useful for experimenting with the Move Steering and Move Tank blocks […]
