1 2 PAGE 56 SECTION 6 STUDENT JOB SHEET 5A Copymaster for use with 9795 GROUP DATE Programming the Home of the Future Make your Home of the Future more “futuristic” by controlling some of the RCX functions over the Internet. The programs you write can be downloaded to an RCX located near a computer running ROBOLAB that is linked through the Internet.The two computers can be in the same room or almost anywhere in the world! Note: you need two computers and an Internet connection with a known IP address. One computer must have the IR Transmitter and RCX set up and ready to go. If you have not tried this before, see the online documentation, Internet Control of the RCX.You can download it from http://www.lego.com/dacta/robolab/. Click on Resources then Downloads. First set up the ROBOLAB Server computer and the RCX with the Home of the Future model you want to control.To start the ROBOLAB Server software, navigate to the ROBOLAB/Extras folder and double click on ROBOLAB Server.After starting the ROBOLAB Server, the computer and RCX are ready to receive programs over the Internet. Now you can use the Internet sub menu of the Programmer - Inventor Level 4 or in the Investigator - Program Level 5 to create programs for controlling your Home of the Future. You can create new programs or adapt existing programs to the Internet mode. Every program that you to send over the Internet to an RCX must use the Internet Begin and End commands. The Internet Begin command is used instead of the standard Begin command in ROBOLAB programs.The IP address of the remote computer that will be transmitting the program to the RCX must be specified. The remote computer must be running ROBOLAB Server. The Internet End command is used at the end of every Investigator or Inventor Internet program that begins with the Internet Begin Command.
3 4 5 6 SECTION 6 STUDENT JOB SHEET 5B Copymaster for use with 9795 GROUP DATE Programming the Home of the Future The String modifier is used to specify the IP address of the remote computer. You send the program over the Internet the same way you download: by pressing the Run arrow on the ROBOLAB screen. Here is a program that turns on the lamp in port A and turns on a motorized machine attached to port C.The lamp and motor stay on for two seconds, then turn off.This program is sent to the remote computer with IP address 130.64.208.54. The remote computer then downloads the program to the remote RCX. Note: The remote computer must be running the ROBOLAB Server and have an IR Transmitter attached with the remote RCX on and nearby. After the program is downloaded to the remote RCX, someone must press the Run button on the RCX to start the program. Here is a program that controls the automatic garage door. First, the lamp across from the light sensor turns on.When the car going past activates the light sensor, the garage door opens and closes. Here is an example of a security system program that you can download from the local computer to a remote computer (that is running ROBOLAB Server). If someone activates the light sensor, the lamp turns on and an alarm noise sounds.This program was created in Investigator - Program Level 5 so the data from the light sensor is collected and can be uploaded. You can also send programs over the Internet to the RCX to control the RCX directly.That means the RCX runs the program immediately - it does not wait for someone to press the Run button. To create an Internet Direct Mode program, replace the Internet Begin and Internet End commands with the Begin Internet Direct Mode and End Internet Direct Mode commands. Note: Programs for Internet control of the RCX can be as complex as any of the conventional RCX programs for your local computer. There are a few exceptions - ROBOLAB Server does not support Internet Direct Mode for programs with Data Acquisition or Looping structures. However, these formats are supported by the Internet Mode.
