This clip shows the possibilities of NXT WOW. I spent several hours trying to improve my understanding of PID Control. After quitting last night, however, I refocused on the human intelligence. What can we learn from kids who have developed these kinesthetic skills that will help us to help all students to achieve at high levels?

Mathematica Solution to the GyroBot Control

A Google search (forces inverted pedulum angular rate) produced this online view into a Mathematica Notebook addressing the challenge of robot control.



Note the much greater complexity than the solution that Barello describes in his version of the GyroBot. Perhaps we can derive insight from this demonstration to see how to implement an easier solution. Also note that Mathematica even provides a free viewer tool that allows an intermediate level of access to the model.

Ariel, Laurel and Alyssa share in Frau Adams' class

Frau Adams invited students in her 8th grade German class to submit weather projects in multimedia formats of students' personal preferences. Ariel and Laurel chose to extend their work with the green screen in ITeam for this assignment. Here, they set up to share their production with their class. I wanted to submit a brief video clip of their presentation to the class but Blogger would not accept the video file submitted this way as described here and here.

This image comes from the camera album in the gallery.
This method does not require the end termination. I also needed to add tags manually.

ReTest post to blogger with attached image

This post ideally should contain a title. This text with appropriate formatting.

The AndroidLegoRemote video. It did not take the video.

Now trying a jpg image. And a tag escape.

And none of the signature stuff after an end command. The end command worked as described in help but my attempt to probe the system for undocumented functionality did not produce the desired result:
#tag test
I needed to add the labels to the post manually.

Sharing video of learning process

Blogspot gives me a tool for adding video to this post. Will it work any better than the Video Upgrade at Wordpress.com?

I have been trying to locate one of my videos of this subject on my MLTI laptop and it is anything but straightforward. I can easily find and view the video I want but so far, I cannot get the file url into the upload tool.



By using the "Save for Web" item under the file menu of QuickTime, I was able to create and find the file for upload. While that convoluted process might have sufficed in the past, it doesn't encourage routine use. What can we do to facilitate easier use?
