How to Test the Dune Buggy - Classroom Test

1. Using the remote controller, test the controls and switches to make sure that all of the components are moving as planned.  Check for stuck, jammed, or parts that move to fast/slow.
2. Using a small container of sand, check to make sure the scoop is able to collect and contain the sediment sample.  Check to see that sample does not significantly slow down robot.  Check to see if the sample stays secure inside the scoop during transportation.
3. Make sure the video camera works by moving at various distances in the building.  Picture should be clear and give an accurate representation of the area by showing prominent landmarks, obstacles, etc.
4. Check to see that claw opens and closes properly.  Pick up object around the room to simulate the robot picking up dune grass.  Ensure that the claw is able to cut sample using paper or actual dune grass collected from the field.
5.  Make sure that the arm is able to turn and swivel the camera properly.  Ensure that a clear image is still transmitted to the operator and that the arm does not obstruct view of landscape.

Status Report 11/8

I haven't logged in the past few days because we have been presenting in the media center.  So far, I have delivered my presentation to the class about the status of my project.  In addition, I successfully completed the construction of two important models: the claw and the scoop.  Both designs were created out of Lego pieces and had movable parts to that the audience would have a better understanding of how the components would actually work.  Finally, I was able to take apart two remote controlled RC cars to see how they worked.  Doing this allowed my partner and I to get a better feel of how to incorporate certain designs into our final product.

Status Report - 10/28

This week, I was able to get my hands dirty by experimenting with some real servomotors and motors.  In addition, my partner PA and I were able to take apart old RC cars to see how they worked.   By doing this, we can incorporate this into our product.  We also completed the construction of our models.  Using a Lego kit, I was able to create models of the claw and scoop mechanisms.

Status Report - 10/20

Today, I will be starting the model with my partner, PA.  We plan on constructing the work with Lego pieces so it can perform some basic functions to give audiences a better idea of the the robot will be capable of.
