ROS Developers LIVE Class #72: Why is my Robot Arm not moving?

In this class, you will learn how to detect common errors that prevent the robot from moving.

**Why is so important to learn this topic?**

In many cases, it happens that although we have the robot in the simulation, it cannot produce any type of movement. It cannot even hold firmly, in the case of being robotic arms. This is very common due to errors in the controllers. It is very important to know how to detect them and verify where they originated.

There are various types of controllers. Many of these allow the movement of different joints, or the final effectors, and there are even controllers that allow trajectories. That is why it is important to have knowledge of them and know how they work. Although these errors may seem simple, finding and tracking them can become an arduous task, which any ROS DEVELOPER has dealt with.

This ROSject has been created by Christian Chavez and Ricardo Tellez from The Construct. You can use this ROSject freely as long as you keep this notice.

The whole code will be provided to all the attendants of the class.

============================
Every Tuesday @ 6 PM CET.

This is a LIVE Class on how to develop with ROS. In Live Classes, you will practice with me at the same time that I explain, with the provided free ROS material.

IMPORTANT: Remember to be on time for the class because at the beginning of the class, we will share the code with the attendants for free.

IMPORTANT 2: In order to start practicing quickly, we are using the ROS Development Studio. You will need a free account to attend the class. Go to http://rosds.online and create an account prior to the class.
