Use current laser diode and receiver circuit to transmit data at slow speeds. Utilize 1 Raspberry Pi with four python scripts to accomplish this task. One script shall convert the data into binary and export it into a .csv, then another script shall read this file and transmit it through laser flashes. A receiving program will read LDR values from the photoresistor and export them into a .csv file, and a final script will take that data and convert it back into readable values.

Figure out how to get width x length dimensions from the contour box from openCV libraries.

Interrupts are supposedly faster and can help us increase the transmission rate.

Continue to refine the data transmission code on the Arduino in order to increase the speed. The maximum based on the Arduino reference guide is 333.33 kHz. This includes using a photodiode as well.

Code is here https://playground.arduino.cc/Code/PCMAudio/. Will attempt to recreate this project.

Figure out why the current CV code does not work well outside of isolated cases (where the paper is on the desk and the camera is pointed directly at it).

Currently have a consistent circle detection code that can recognize circular objects within some tolerance. We will want to be able to detect circles through a wider range of distances and have it be more consistent as it translates left and right (across) the screen.

Figure out what the last few lines of the distance_to_camera.py file do. More info on trello card.

This is on distance-read branch.

The prototype uplink system will simulate the uplink mechanism during real CubeSat docking. The ground station will be a laptop running a Python program; this program generates a large array of data that will be piped into the Arduino using a serial connection. The Arduino will send the data using the previously written code. The receiver Arduino will receive and reconstruct the message. This Arduino will then send the array of initial data into a Raspberry Pi where it will be used for guidance.

The receiver will be attached to the testbed, and all guidance will allow the testbed robot to maneuver in specific ways.

Due to the speed limitations of Python, small differences in the laser and receiver code would shift the timing, thus destroying the data. Hopefully, conversion to C will allow an increase to .001 second flash and response time.
