Capturing Data

The upload area allows you to upload data from the RCX to the computer and view it on a graph. 

Data sets are uploaded from the RCX to ROBOLAB in the upload window. All data sets are plotted on their own page in the 
upload area. If data from more than one sensor is acquired when the RCX program is run, upload opens a new page for 
each data set. A window tells you how many data sets were uploaded. All pages are listed in a Page Control Area of the 
Navigator

Once the data is uploaded, it appears in a plot in the upload area. The plot is labelled with the sensor value on the y-axis 
and time on the x-axis. The data display can be changed by selecting a new plot type.

Data sets plotted on the upload page are stored in bins. More than one data set can be stored in the same bin. Bins are 
designated by colour. Selecting different bin colours is useful to separate the data from different sensors. You can also 
name the bins and change their colour.

You have two options when capturing data: 
1. Download the program to the RCX and store it until you are ready to run and capture data.
2. You can select a Direct Mode, which downloads the program to the RCX and begins capturing data and showing it on 
the computer immediately.

Ideas for practicing your skills in Investigator

Using different sensors for data logging, there are unlimited ways to use Investigator. 
Here are a few suggestions:

• You want to fi nd out the light and temperature conditions in a cave, but it is too dangerous to go in yourself. Send in an     
  RCX rover instead
• Build and program a device to cool down your drink as fast as possible. Include a temperature sensor to measure how  
  long it takes to cool
• What is the speed of your car? Use the light sensor mounted on an RCX car to track the distance traveled
• Construct a smart golf club. It should keep track of the strokes you’ve played by using a touch sensor to record each    
  time you hit the ball.
• Create a Weather Station (data logging temperature, humidity, downfall)
• Use the rotation sensor for measuring the speed of a non motor vehicle running down an inclined plane
