Project: Dim Sum Robot #1
We are rebooting the Dim Sum Robot project with a new head-master Today, we start by exploring the basic design and core functions of our Dim Sum Robot, in order to take a decision on the hardware to use for this project. Basic Design CPU Looking at CPU available and their characteristics to allow us to choose a good fit for the project.
