Jed and I trimmed even more weight off of the small segway, and even chose to remove the board from atop the segway. With only a few days remaining to work, and only a few kinks to work out, I am still optimistic that we can finish this project.
After finding the original segway was too heavy for the stepper motor to move, Jed and I designed a much smaller segway. The new design has a single smaller piece from the VEX kits, hopefully the stepper motor will be able to move this smaller design.
This week I assisted Jed in the creation of the segway; it uses assorted VEX parts and makes sure to stay simple so that less can go wrong. Continue reading Design and Developememt
I have now moved from the Autonomous Car project into helping Jed with his gyroscope project. It originally started trying to make a reverse pendulum (segway) that balances itself. Continue reading Reuniting the VEX Team
This week saw the integration of the GPS unit and code into the Autonomous Car, finally creating the first true version of the Autonomous GPS Car. Continue reading A Union of Two Designs
With the Vex Competition over, I am now assisting Austin in perfecting the Autonomous Car. After adding a second sensor the car can now turn left or right, depending on which would avoid an obstacle better.
Today was a great day in the field of robotics. Most of the morning was spent in the high school cafeteria, except today it was an arena for robotic competition.
With only four days left to work on the remote control robot for the VEX Robotics competition, we may be able to finish the arm on time. The arm is, for the most part, designed and is being mounted on the car as I am writing this. I feel we have a strong chance at winning the competition next Saturday, but we’ll be putting out our best effort no matter how the results turn out.
The updated GPS for the autonomous car was finished this week. A small sensor called a magnetometer arrived early in the week, it’s essentially a very accurate compass. After some fine tuning and editing of the code, the new GPS unit can tell you to turn either right or left when navigating to a set point.
This week saw the creation of many things. One of these creations was a circuit that interprets data from a GPS chip then displays things like the distance to a set location, with the heading and direction to the location, and how many satellites the chip is getting signal from.
