CMU Data Logging Tutorial for NXT-G 2.0


Carnegie-Mellon has posted eight, flash-based videos on how to use the new data logging feature in NXT-G 2.0. The videos are here.

Cool! I can't wait to get my hands on a copy of this software!

Clgfive,

I feel the same way.

The automatic data logging capabilities of the software make the NXT more useful as an experimental device. (The NXT always had data logging capabilities, but the new software makes gathering data easier for the rank-and-file user).

I'm just as excited about the exportable "My Block" features of the software. Any one who has used My Blocks knows the frustration of trying to share their programs with someone else, only to have them not work because of missing "My Block" components. The new software will (hopefully) make it possible to share complex programs easily.

Rick Rhodes, using the word "frustration" in relation to the My Block features of the 1.1 version is a huge understatement.

However I daresay the words I would choose would very quickly be deleted.

Anyone know where they got the Temp. Sensor?

Christopher B,

The temp sensor is sold by Lego Education:

Thanks.

I have the old temp sensors which require the converter cable to work w/ NXT. Does anyone know how this one compares w/ that one on accuracy, time for temp assessment? This one has a long probe so it could be immersed more deeply in liquids than the other.

Here is the link to the old temp sensor: http://www.legoeducation.com/store/detail.aspx?CategoryID=177&by=9&ID=324&c=1&t=0&l=0

Does the new temp sensor have a permanent cable attached?

It wasn't clear to me from viewing the tutorials if you had to be connected to a computer in order to data log. Can you collect data in the field and then come back and download it into the data logging/analysis program?

Rick Rhodes said...

Anonymous,

One of the publicity releases for the new software states that, "autonomous robots can log data" and that the software will support "both remote and live data logging".

In other words, the software enables data logging without being tethered to a computer.

Anonymous,

According to a (seemingly authoritative) post on NXTlog, the new temp sensor DOES have a permanent cable.

Matthias Paul Scholz said...

Yes it has.
As a far as I know, the reason is that the temperature sensor is meant to be used in fluids also and the plug for the cable would have been a soft spot for possible harm to the electronics.

I would assume you can do live datalogging via bluetooth as long as the robot is in range?
