There are many times in my design career that I needed to translate an object without rotating. Lifting an object on a table is a great example of this. At an airport we may see a baggage loader using a scissor lift to load and unload your personal items. In most cases, we want to maintain level with the ground, but often we just need to keep the same angle. I once designed a holder for a seam welding robot that needed to keep the tip at a specific angle relative to the part. It was not horizontal.
We will discuss three of these methods in this video series.
