Hello @humberto, welcome to the forum! It’s great that you’re using Stretch in your thesis. I would recommend starting with the Getting to Know Stretch tutorials. The series includes:
- A safety guide - highly recommend starting with this guide for your own safety!
- Quick start - get a feel for what you can do with Stretch by using the xbox controller to teleop Stretch around. Also, this guide introduces the Python library, Stretch Body.
- Best Practices - info about keeping the battery healthy, and how to handle the robot while it’s off or on. In particular, I recommend taking the battery maintenance guide seriously, since battery damage can cause you unnecessary delays.
The ROS tutorials you’ve linked is a good next step after going through these getting started tutorials.
