  • $\begingroup$ Welcome to Robotics William, but I'm afraid that Unbounded Design Questions are off-topic because there are many ways to solve any given design problem. Please also focus your post to a single question. We prefer practical, answerable questions based on actual problems that you face, so questions which ask for a list of approaches or a subjective recommendation on a method (for how to build something, how to accomplish something, what something is capable of, etc.) are off-topic. $\endgroup$ – Ben Mar 15 '20 at 22:58
