If you want the program to only run for a certain amount of time and then stop, I would recommend using the first program, but changing the while loop condition to stop looping after a certain amount of time. As to why it always defaulted to the third case, it’s possible that when the program first starts, the sensor gets a couple of bad readings because it’s still “warming up.” You wouldn’t notice these in the first program because it’s checking the sensor continuously a couple hundred times a second.

Under the Robot menu, choose Download Program. Turn on the NXT brick and connect it to the USB port of the com-puter. Save your program under the name HelloWorld'. Type the text exactly as it appears in Listing 3.1 into the editor window. Then the program exits.įrom this description, we can conclude that the program is only checking the IR sensor one time. Give the students the Description and /or the Psuedocode, and have them demonstrate proficiency by writing the program or making it work. To execute these instructions on the NXT, run the RobotC program. Then, regardless of the case, the program waits for 5 seconds. Based off of the results of these comparisons, it sets the motors to either drive straight, turn right or turn left. When the program starts, it does three comparisons, seeing whether the value returned by the IR sensor is equal to, greater than, or less than 5. Start by reading through your second program, and restating it in English: Any help with this would be very much appreciated. Therefore, I am a tad stuck as to why it isn’t changing when the beacon is in different positions.

I made sure that it wasn’t a physical problem with the bot by running our previous code and it still worked as well as it did before. Instead of doing the desired task when the IR beacon was at different positions, each time it defaulted to the third section which is what it is supposed to do only when the sensor value is < 5. For example, Bump or Potentiometer Value. However, when looking at the code and testing it with the IR beacon on the ring dispenser I realized I needed something that stopped a just slightly before reaching the ring rack so that we could place the ring instead of the code going on infinitely. allow you to create behaviors where the robot uses a digital or analog sensor to control the next line of code. This worked very well and did exactly what it was intended to do follow the IR beacon infinitely. I started off with a more basic and conventional IR Code as follows: I was recently working on a program that uses the IR Beacon for this year’s FTC Game. I am a student on a FTC team with a question regarding IR sensor coding in RobotC.
