Our objective is to move a spherical magnet in a circular trajectory while it is suspended in a soft gel. Why so specific and seemingly arbitrary? This is to demonstrate the potential applications of minimally invasive surgeries. In our demonstration, the soft gel is meant to simulate brain tissue, and the spherical magnet is meant to simulate a medical device. Our challenge lies in controlling its motion.

Week 4 Update
The team is making solid progress towards their goal. All the separate components like the image processing script, 3-D CAD components, and motor control scripts are nearing their final versions. This allows them to fall into place for the final project. The image processing and motor control scripts were combined together in a single script. The goal was to have the motor spin at different speeds depending on the position of the magnet. The team improvised a moving magnet with a dark circle drawn on a piece of paper. We then moved it in front of the camera and watched as the motor moved at different speeds. A great success! Now we can move to tweak the parameters so that the motor can spin at the best speeds to accomplish the task at hand. Finally, the team received the materials to make the gel. We will need to conduct additional research in order to determine how to make our gel. Looking ahead, we have our solid framework for us to conduct tests on. From our tests, we can edit our framework a bit to get our desired final result.
