An arc turn is a turn where both wheels are going in the same direction, but one is going faster.
To program the robot to make an arc turn, we use the third block of the Movement palette. This is the block for movement with direction control.
The block has a movement length setting that works the same way as in the first move block. Here's how it affects the length of the turn:
Of course, there is also a setting for the direction, which, unlike the first block, is much more precise.
The direction can be set from -100 to 100, and at these values the robot turns left and right in place. For all other values, the robot turns in an arc, and the higher the number, the sharper the turn. Here's how the direction setting affects the turn:

Level A1 - Space Adventure - Robotics with LEGO SPIKE Prime
This is the first level of the LEGO Robotics Curriculum for second, third, and fourth-grade students.
A "space adventure" but with robots. Different robot structures are built in Level A1. The motors are controlled so that the robots perform precise movements around the "Earth", "Moon" and "Sun". We use the force sensor to overcome various obstacles we bump into. We learn interesting facts about the solar system and space vehicles.

Lesson 3 - Satellite
Introduction
In today's lesson, we will create a small robot that demonstrates the process of making circular turns, known as arc turns. The lesson will focus on satellites and their practical applications in our daily lives.
A satellite refers to a companion or an object that moves alongside another. Earth's natural satellite is the Moon, while artificial satellites are small spacecraft launched into Earth's orbit with the assistance of rockets.
An orbit represents the imaginary path that a satellite follows as it revolves around the Earth. Today, we will program our robots to move in circular orbits. Additionally, it's worth noting that some orbits resemble an ellipse and are referred to as elliptical orbits.
