There are no new unread posts for this topic.   I am ready to teach my students about the light sensor and plan on using the Line runner challenge 1 with this class, as the main challenge. From what I have read, there is more that I need to teach them in order to be able to detect the lines with the light sensor and then return to the start and so forth, until the robot has reached all of the lines in the challenge. What other units do they need to know about before attempting this challenge? Thank you. Line Runner Challenge

I've been using RobotC for about a year know, and I've recently been wanting to apply image processing (e.g. object identification and/or facial recognition) using a 3rd party camera to my Vex Cortex.. I can't seem to find any support towards this idea directly through RobotC, so I downloaded a library called OpenCV, but when I tried to include and compile the files, I came up with errors of unknown commands. Is there a way to apply image processing directly through RobotC, or... Usage of image processing with 3rd party camera

I've started a project where i use 2 motors to control the nobs on a etch-a-sketch.. I've tried to do some research on this and have not found anything that would help me. I would like to know if you need ant extra parts to control the acceleromiters built in the controller. A sample code would help a lot. How do i access acceleromiters built in the vez controller?

I am trying to create a robot that finds an object, grips it, and then returns to me. I was thinking of using a global variable and maybe a while loop that increments this variable until it finds the object? However my main question is, how could I make it so the robot keeps track of its turns and what not? Here is what I have so far (look in my... Keeping track of movement

I have consulted The masterminds of Reddit's FTC subreddit, and two different people said all you have to do is have two motors with encoders and PID enabled, and they will try to match each other when you set them to the same speed. However, our programming mentor insists it's not that simple. Who's right here? What do I need to do to get this working? TETRIX Motor PID Control

Unfortunately, robotc uses a modified (and undocumented?) specification with the custom firmware.

There are no new unread posts for this topic.   Hello all! I'm trying to make a program, where the robot is moving straight for demanded time (long, like 10s) but if the robot during the move detects the change of surface (eg. color change), it stops. The important is the time cannot be changed for less (it would be to easy ;) ) I know the idea how it should be done however each time I tried with different tools it did't work. I don't know how to have the robot stop executing previous task if the change of color is detected. Now I am trying... Aborting previous task

in ROBOTC for LEGO MINDSTORMS
