You have 3 joints with 3 dimensions. So 9 variables you can control. If each variable has 10 choices, and you need to make a choice for each, that is 10^9 possible combinations.
- whimsicalism 5y ago"3 joints" -> What are the 3 dimensions that joints move along? I naively would have thought one or two (ie. how much spin on one axis and how much spin on the other axis) just by naively looking at my elbow for a second. For an arm of fixed length, polar coordinates have 2 dof.
- hervature 5y agoYes, there are multiple types of joints. In this case, you could think of a ball joint like a shoulder or hip. They move "up-down" and "left-right" but also rotate.
