I have two questions.

I'm sorry, I'm new to this field
How can I use the toolbox to create my own robot?
How do I use the toolbox for arm trajectory planning?

That's a big question. You need to be familiar with underlying concepts, the approach in Robotics, Vision & Control book is SIMILAR to this. Have a look at the examples, included with the toolbox, as well.

Thank you for your interest in RTB. Building your own robot and planning trajectories are both covered in the wiki pages Introduction to robot and link classes and Trajectories, and in the example notebooks. I'm closing this as resolved. If you have a specific question, please open a new discussion.

Hi Prof. Corke,
I’d like to express my gratitude for your help a while ago. I’ve finished my master’s study and work at a Chinese state-owned enterprise now. Although my current job is administrative and unrelated to robotics, I still value what I learned from your toolbox.
Best wishes to you!

Thank you for letting me know, and congratulations on finishing your master's. I'm glad the toolbox was useful while you were learning, and I hope what you learned serves you well, whatever the work. Best wishes to you too.
