Project Preference
Autonomous Power Wheel Mobile Robot Hallway Navigation Wind Turbine

Problem Statement
The goal of the project is to build a system that is able to control a power wheel autonomously.

Project Plan
Briefly describe your group's plan for the next 4 weeks, including major tasks that will be completed each week.

Week 1 Narrative
This week I read over the previous groups CDIO reports and gathered information from their designs of the platform that held the system together, while taking notes on why it worked or did not work. I also looked over at the platform that left from the previous team. Using the preliminary design that was drawn during our last meeting, for the actuator and gas pedal, I was able to come up with some simple concepts of how we should implement the platform.

Week 2 Narrative
Overall,our group started building on a prototype for our system. The steering wheel and the gas pedal were finished this week. This week I mainly worked on the 3d modeling for some parts we need and the prototype gas pedal with Israh. Below is a basic drawing of what our prototype gas pedal look like.

Week 3 Narrative
This week I was able to finalize and print the parts we needed for the pedal actuator. The bracket and the piston. I redesigned the bracket so that It would be able to be easily removable when attached to the platform. I added 2 extensions to the model that will allow it to be screwed in. I also updated the pictures form week 2 with the measurements.

Week 4 Narrative
Code:

I mainly focused on this part off the code

Here is the code we modified to make a figure of 8. Since our steering actuator broke, I only had the chance to test the pedal motor.this is also the reason why the steering actuator commands are commented out (//). Here is a video recorded by Justin while we were testing the pedal. Gas Pedal Presser Test Video http://youtu.be/gIV6zhy3gRI. Some problems I encountered was running the gas pedal motor while the code was in the setup statement, I ended up putting it back to the loop statement where it successfully worked. Also powering the arduino, Initially I thought the motor shield could power the arduino on its own but It was not working;then I realized that the arduino needs a power source of its own.For testing, I used a ac adapter for our prototype.
