NXT, AppInventor and ?! [1st DRAFT]

Interrobang invites students to participate in missions and share their work as deeds that are reviewed before publication on their website Ariel and I are evaluating the environment by submitting a collaborative mission. Interrobang held our work in limbo for more than three days.

Sunday evening they returned access to our work with a request to revise before they will accept it. The reviewer suggested that we add some video to our contribution.

Deed Needs Revisions

The deed you submitted for the mission "Knowledge Swap" needs some more work before it can be approved. You can keep working on it and submit it again at any time.

Here's what you need to work on:
This is very cool and we want to accept the deed -- but I think it can be much more illuminating to the community if you also upload a little video of what you're doing. Is that possible? We'll give you more points if you do so. Thanks!

So, I am saving it here as part of our development process and evaluation.

"Ariel M. and I worked together combining her knowledge of NXT and mine of AppInventor"

I am developing experience with AppInventor and track the new features as they are released. When I saw that Liz Looney was developing AppInventor support for NXT robotics, I anticipated that this would be highly engaging for ITeam members.

Ariel uses NXT robotics outside of school. She showed me how to use the NXT module and test a variety of sensors. For example, she used the ultrasonic distance sensor to determine its range (~1 to 90 inches). We connected it to math by measuring the maximum distance and comparing it with the distance we measured (as 7.5 x 12" tiles on the floor outside he library).

We could make an even more engaged connection with STEM by conducting a more complete comparison of observed (sensor) with measured (tape measure) distances and plotting those for analysis and interpretation. Once ITeam members are sufficiently familiar with the tools, we may be able to help MAMS sixth-grade teachers and Ms. Hogan, the technology integrator, incorporate ideas into the force and motion unit that they are developing.

We were able to connect the phone to the NXT Bluetooth and control both the tone generation and a test motor! Ariel was sufficiently excited that she started building the robot described in the NXT instructions booklet.

12/10/10- Today we worked on adding another motor to the robot. We also took some pictures of what we were doing. Hopefully by next week we will have the motors put together and many more pictures.
