Differential locking mechanism - simple LEGO EV3 attachment

Differential locking mechanism - simple LEGO EV3 attachment for the robot Francesco 2

This attachment is meant to be built on the robot Francesco 2. When the red connector for the transmission connects the two axles for the rear gear wheels, the differential locks and the motor starts evenly transferring its power to both wheels.

When the red connector for the transmission is pushed to the side, the differential unlocks and once again transfers its power to the wheel with least resistance.

You can see empty beams hovering over this attachment. They are there so you can attach a lever construction over it, to help with the locking and unlocking of the differential. Similar leaver can be seen in the robot Catapult.

Courses and lessons with this Material

This Material is used in the following courses and lessons

Level C1. "Transportation". Robotics with LEGO

This is the fifth level in the Robotics with LEGO curriculum for students in third or fourth grade.

For the first time robots with steering wheels are built in this level. Those robots use one or two drive motors. The work of the differential and its usage in vehicles is explored. Students learn in-depth the working of the light sensor to create better line-following programs. The first two-wheeled motorcycle-robot is built.

Lesson 3 - Differential

Introduction

Today we build LEGO vehicle with differential! This will be the robot that would be closest to real automobile with rear wheel drive. We will learn why the differential is the solution to the different speed of the wheels during turns and what happens in case of lack of traction!

Robotics with LEGO - Level 2.0 - Robots in Factories

The third level of the Robotics with LEGO curriculum for students from fifth to twelfth grades.

Robots in this level use two or three sensors at a time and students create more complex programs for them. The work of the differential and its usage in vehicles with one drive motor is explored. Robots interact with each other and transfer information or material between themselves. Students learn in depth how to create smoother line-following programs. In the end of the workday, robots leave the conveyor belt and relax with a recreational game of volleyball.
