I’m reading some books about building robot, I think I will start with some basic embedded programming (such as ARM), and once I know more I may try to build some robot.
I used not to be good at hardware stuffs, but I think I can still try now and also it is the time to build up hobbies for retirement although it is tens of years to go.
I will try to use Ada and if it is not available, I will try Java. I will try my best to avoid C/C++ as I need something new to refresh my brain.
