Week 13: Rapid Prototyping

For this week, we focused on implementing the transmitter and receivers to communicate with each other by the physical motion of the joystick. We wanted to set up the controls system so that if we push the joystick in the positive x axis, the DC motor would rotate clockwise, and counterclockwise when pushed in the negative y axis. Additionally, Cheuk came up with the idea of incorporating the kill switch by using the clicking feature on the joystick. We decided to gear towards this direction because it would be cost effective since we initially had the idea of creating a separate mechanism. Although we were not successfully able to integrate the joystick and the transreceivers together in the workshop, Cheuk and I met up outside to finish the rapid prototype in time for our presentation. After understanding how the RF24 library worked, we were able to troubleshoot what was initially wrong with our program and get the mechanism to work! Posted below is the video of our rapid prototype where the DC motor is controlled by the user using a joystick. Additionally, the video portrays how the kill switch was used to shut down the motor.

Week 3: Lightening Talk

For this week, we presented a quick yet informative presentation about what our Full Scale controls team plan on working on. My personal responsibility in our lightening talk was to explain what a controls system is and the referenced the 1/12th scale models vehicle controls team. We did this because there weren't any previous documentations in the archive about full scales controls. I explained that in the input aspect of the system, the 1/12th scale model incorporated switches, hall effect sensors, sonars, encoders and RFID. For their output of their system, they used motors, servos and LEDs. Additionally, I briefly explained how they used an Arduino Mega as their microcontroller. Lastly, I explained to the rest of the team that our goal is to get our full scale pod car from point A to point B and vice versa in a safe and efficient way. After all the lightening talks were finished, we separated into our respective groups. Me and Cheuk talked about how we should continue researc

Week 7 (Spring 2018): Component Box for Full Scale Controls System

In this week's meeting, we had the whole meeting to meet with our respective sub-teams and work on implementing our final design. After getting feedback last week from Dr. Furman and Eric, we discussed the voltage requirement that we would need to power the motor. Thus we met up with the Full Scale Solar team to discuss how many batteries we would need as well as if their system would be able to charge our batteries efficiently. We discussed using 1 or 2 12V lead-acid batteries to power our controls system. We discussed with Dan from the Full Scale Bogie team that for our demonstration, we would not need the full 48V to drive the motor since we're running it at a slow speed. Additionally, Cheuk and I discussed where we would be placing our electrical components within the podcar system.

Week 2: Introduction

In today's meeting, we met with Dr. Furman and Eric at our respective facility near campus. At the facility, we were introduced to the 1/12th, 1/2 and full scale model of the Spartan Superway. Dr. Furman and Eric assigned everyone to their respective groups. I have been assigned to work on the controls system of the full scale model for the Spartan Superway with Cheuk Kwan. We plan on getting in contact with the prior Full-Scale Team and reading last year's archives to be up to date with the project and smoothly transition into forwarding the team's agenda. For Cheuk and I, we will be concentrating on using a micro-controller to drive and control the bogey motor drivers and sensors to designate the pod to travel safely from one destination to another. Additionally, we plan on setting up our sub-team's blog and researching more about controls systems.
