RC, solder-it-yourself, or Alfredo NoU3 — figure out what your robot's brain should be before you buy anything.
Every robot needs two things before it can move: a brain that decides what the motors do, and a battery to power it all. There are three very different ways to build that brain, and the right one depends on how much you want to code, solder, and spend. This guide walks you through the trade-offs so you can buy the right parts the first time.
