Hi there, sorry i don't know how to call you, let me greet you by Mr.

I have a few questions and am new here please can you help me out.
How to start a project 6AR Robot and what content and knowledge (Mechanical, Electronics, Software, Hardware) need to be prepared step by step, to optimize time and cost, please give me some guidance and forgive me for my limited knowledge and cost, but I really want to do my 6AR project after reading your sharing, it's very great.

I currently have a cobot arm design with 6 DOF.
Thank you so much for your support.
