In considering the direction I want to take for my final project in XYZ, the class I’m taking that is most focused on robotics, I had a few personal preferences that I wanted to satisfy:
- It will move in an unexpected way
- It will have a perceivable logic
- It will not have a gantry
So far, the robots that we have studied and discussed moved in a manner that can readily be described as mechanical. This means that they moved in fixed velocities and straight lines. This is useful when accuracy is prioritized. This project, however, will be partially defined by its movements, so I would prioritize the manner in which it moves over its accuracy. Ultimately, I would like it to move in a way that appears more natural and less mechanical.
This one can be achieved in a number of ways. Every drawing machine or CNC milling machine ticks this box. When they are performing a job, the result emerges and the user can see what the machine is doing. I don’t intend to make this into a drawing machine (but it still may end up becoming one…) so making sure that its movements follow some predictable logic will be a challenge.
Many of the robots discussed in class utilized a gantry, a set of tracks or rails upon which the motorized head moves. Often the size of the gantry is what limits the size of the object being produced. When starting this class, I really wanted to make something that wasn’t inhibited by a gantry’s limitations. Robotic arms, while limited in their physical reach don’t require a gantry.
