Logging Data to Disk

While running the motors, it is possible to have Roborun capture all the parameters that were displayed on the various fields and charts and save them to disk. The log function is capable of recording 32,000 complete sets of parameters, which adds up to approximately 30 minutes of recording time. The figure below details the buttons and check boxes needed to operate this function.

1- Log Check Box

When checked, Roborun will capture all the parameters and save them in local RAM. The data is not saved to disk until the “Save to Disk” button is pressed. Data is being captured for as long as the program is in the Run mode, whether or not a motor command is applied.

2- Clear Log

This button can be pressed at any time to clear the local RAM from its content. Clearing the log also has the effect of resetting the timer.

3- Log Fill Status

This gray text box indicates whether the local RAM log is empty, full or in-between.

4- Reset Timer button

The timer automatically runs when the Run button is pressed and data is being exchanged with the controller, regardless of whether or not logging is activated. This button resets the timer.

5- Save Log to Disk button

Pressing this button will prompt the user to select a filename and location where to copy the logged data. The file format is a regular text file with each parameter saved one after the other, separated by a coma. The file extension automatically defaults to .csv (coma separated values) so that the data can be imported directly into Microsoft Excel. The first line of the save file contains the Header names. Each following line contains a complete set of parameters. The Header name, order and parameter definition is shown in Table 32:

TABLE 32. Logged parameters order, type and definition

Parameter Header	Data type/range	Measured Parameter
Seconds	Integer	Timer value expressed in seconds
Command1	-127 to +127	Command applied to channel 1
Command2	-127 to +127	Command applied to channel 2
