I want to use my Arduino Uno for programming a robotic arm for my school project.
The robotic arm that I will use is the C-S 113. The Arm will have to draw an equation on paper.
Will Arduino Uno handle this or should I upgrade to a more powerful one?
From a programming point-of-view, your UNO will be fine.
Just don't supply power to the arm directly from the UNO board. Those stepper motors would suck a fair bit of current.
Actually, I just read (the power supply section of) the pdf on the arm and it has it's own power supply, so you're good-to-go. The PSU supplies 6A for the steppers.
That looks like a pretty nice arm - wish I had one.
