Instead of aligning forward as in the previous tutorial we felt there is a need to demonstrate how we could align backward when moving with the robot. This is not a rare case. The attachments of the robot are generally at the front of the robot and especially during FIRST LEGO League competitions the robot must move backward very often. It is helpful to have in your toolbox the ability to align backward with the robot.

In this video tutorial, we push two of the mission models with a pinless active attachment with gears. The goal is to push the mission models after the blue lines. This attachment is interesting as it demonstrates a non-straightforward idea of how we can push the mission models. We explain the Scratch program and how we use the motion sensors - you will learn how to turn to a specific angle by using the motion sensor.

From programs that rely entirely on proportional line following to those that use a PID-type program where "P" stands for the proportional line following component, proportional line following has proven to be a core mechanic in line following competitions.

Here, we discuss the effects of applying this method to the two-state duck-following algorithm.

While "multistate line following" can describe a variety of algorithms, this tutorial will cover its implementation using the ducky line-following method.

This is the most basic line-following method, commonly known as the "ducky" line-following method.

Here's one way to program using a color sensor!

What is a color? How does our robot detect it? Learn that here!

Have you ever wondered if your robot can make decisions? Here's how we can make that happen!

Have you ever wondered if your robot can make decisions? Here's how we can achieve that!

There are many cases in programming where you want something to repeat indefinitely. Here's how to achieve that!

This is one of the first sensor blocks you'll learn! Here's how we use it!

Reversity - LEGO SPIKE Prime robot with two motors in reverse directions has two motors placed in opposite directions! If we just put a block that moves them both forward, the robot spins in place. So, how do we move it forward?
