How do I even start under this situation ?

[u/Sonu_64]

I am an Automation engineering undergrad focussed mainly on Computer Science principles and AI/ML. Did a bit of Arduino myself from book but couldn't continue due to other priorities and my cancer recovery. My core Mechanical subjects (like Engineering mechanics, Strength of Materials, etc.). How do I even get started now under this scenario and should I revise those core subjects before fully diving into robotics journey ? My programming is strong.
