June 22, 2009- It's sunny!

The majority of today was used to complete the last of the tasks from Sprint 1.

Reza:
The Forklift Challenge is ready for review; the documents have been peer reviewed, the tutorials are finished and the model is in the designer (although there is a bug with the designing software, like the catapult).

Fara + Brad:
All sensors are inventoried and tested; a write up for each type of sensor has been completed and peer reviewed. These sensors include: Light, Ultrasonic, Color, Infrared and Compass.

Chris and Krista:
The Catapult Challenge has already gone through a formal review and is totally complete.

A little bit of everyone:
The initial activity, Project Zero, has been peer reviewed. The tutorials have been tested and revised as needed and the bots that are to be used for this exercise are complete in the designer. The only thing left to do with this activity is to finish the "Challenge" activity at the end of the document; Brad started working with the color sensor today, he downloaded sound files that will eventually read colors for the students and started on the code. Once the code is smoothed out, the activity will be written up and ready for formal review.

Grabber:
We tested out the grabber robot for a bit today, both in the carpeted lab and in the smooth floors of the Innovation Center. We've come to the conclusion that there is a small flaw in the design of the grabber: the US sensor tends to pick up a reading when there is nothing in front of it. We believe that this is because the US sensor is so low to the ground, moving the sensor to the side of the bot and raising it a few centimeters off the ground level will hopefully fix this problem. If the change in model is made however, the code and tutorials will have to be revised; tomorrow morning we should discuss how much time must be devoted to making the grabber function smoothly and if we have enough time to do it.
