Week 3

Recitation:
Today the blog was fleshed out and organized for ease of access.

The design for the robot has also been worked on, the basic premise of the robot is starting to show. The petri dish holder file was sent to be 3D printed.

Lab:
Today was further work being done on the blog. Three magnetic spheres and the external magnet was acquired.

Figure 3.4: Three Magnetic Spheres

Figure 3.5: The code for the camera.

A camera was acquired and coded to work. Now the process of motion of an object tracking can begin. The code was written in python on Anaconda. The motion tracking was not coded as of figure 3.5's photo being taken.

Further work was done and the motion tracking was completed as shown in figure 3.6. It has the what the camera sees and what it was programmed to see was the magnetic spheres.

Figure 3.6: Code and Picture of Motion Tracking.

Figure 3.7: An example of what the camera can see.

For figure 3.7, the camera was coded to show things in grey, but what is being shown is the stepper motor, the arduino board, the 3D printed petri dish holder, and the petri dish.

The physical system of the stepper motor and the arudino board was created as shown below.

Figure 3.8: Physical System

It was coded as well as shown in figure 3.9. Certain values depend on the kind of rotation is needed. "stepsPerRevolution = " and "myStepper.setSpeed()" are those values need to change.
