A general introduction
This section is for information only and does not include training schedules.
Investigator extends the use of the RCX and ROBOLAB to include the creation of experiments that use programming, data
logging, computation tools, and documentation. The programming tools in Investigator are the same as those found in
Pilot and Inventor Levels with additional commands for data logging.
Students program their RCX to collect information. After running their program, they then upload the collected data, via the
Infrared Tower, to ROBOLAB for further analysis and comparison.
Programming in Investigator
The Program Area of Investigator provides fi ve programming levels. The fi rst three levels are Pilot Templates. Levels 4 and
5 utilise the fl exibility of Inventor Programming.
The type of data captured depends on the sensor selected in the program.
Options include:
Touch Sensor
Light Sensor
Temperature Sensor
Angle Sensor
Rotation Sensor
Generic Sensor for non-LEGO sensors
Navigator
A Navigator tool is provided, providing access to the following functions: (pictured clockwise)
Traffi c Lights—this brings you into the programming area
The White Arrow—this brings you to the upload area, where you upload the data you have gathered
The Buckets—this brings you to a view and compare area, for all the data you have gathered
The Calculator—this brings you to a computing tool where you use arithmetic calculations to compute your data
Investigator
Students can use a Journal tool to:
• Record hypotheses
• Record fi ndings
• Add charts and data to support conclusions
• Publish results for an on-screen presentation
