I’ve really hammered them over the past few months and they’re holding up very nicely.

I bought these class 10 cards very cheaply from DX.com. If you are keen to take part in the beta trials, make sure you buy yourself a 4GB SD card (or bigger), so you can run the special firmware. You can also follow a thread on the ROBOTC forums where the devs post what’s going on. Make sure you keep your eyes peeled as a public beta program will start very soon, once things like LCD and LED control have been added. Motor = nMotorSpeedSetting + round(error * nPfactor) Motor = nMotorSpeedSetting - round(error * nPfactor) #pragma config(Motor, motorC, rightwheel, tmotorEV3_Large, PIDControl, reversed, encoder) #pragma config(Motor, motorB, leftwheel, tmotorEV3_Large, PIDControl, reversed, encoder) This is the linefollower: #pragma config(Sensor, S3, colour, sensorEV3_Color) *!!Code automatically generated by 'ROBOTC' configuration wizard !!*// The don’t-bump-into-the-wall robot: #pragma config(Sensor, S4, sonar4, sensorEV3_Ultrasonic) As you can see, it’s not a lot different from what you’re used to with the NXT or VEX IQ or any other ROBOTC platform. Setup: RobotC is already installed in EBU2-239.

A disadvantage is using RobotC relative to MIT App Inventor is that you will not have the Android features such as texting, motion sensing, or use of the camera.

I fiddled a bit more with it and made a (slow) line following robot:īelow you can find the source code of these programs. An advantage of RobotC is that you are using a single microprocessor, and thus it will quickly control motors based upon sensor input. You can watch variables, sensors and motors.īelow is a video Tim Friez made of his robot not running into a wall. By having a servo motor sway the sensor side to side in a thirty-degree arc, we can measure the distance of an object from both viewable edges.

The debugging windows and all that fun stuff is also working. Attaching a transmitter to the object and a receiver on the follower is the usual solution, but we will only be using one ultrasonic sensor for a challenge. So the status right now is that there’s basic motor and sensor control, so it’s actually possible to make functional robots. However, I did mention in a previous post that I am also working on a massive rewrite of the suite to make it more struct-oriented. The yellow wire in this case is connected to the TRIG pin which is connected to the smart inventor board on pin 4 of PORTD. Hookup the red wire from the VCC pin from the sensor to V on the Inventor board. Some things like I2C will be different but so badly that it will take a lot of work to get it up and running. You will need four female to female jumper cables and of course the ultrasonic sensor.

Pretty soon I can start working on porting the Driver Suite to the EV3. Many bugs and issues were fixed in the base LEGO VM that were causing issues, such as failed auto-id and I2C transactions. The pin stays LOW when no IR light is reflected (meaning the black ring has absorbed the infrared light from the sensor).There has been an enormous amount of progress in the past few weeks on the ROBOTC for EV3. These IR sensors are all the ones on the bottom-left hand side of the Inventor board. This if statement basically checks if IR sensor 11 or 12 or 13 do not detect any IR light. Type the following code into your program: if (digitalRead(11) = LOW|| This is just in case one of the IR sensor fails to detect the line. Our program uses all the IR sensors from pins 11 through pins 18, with the exception of pins 14 and 15. Now we must tell the IR sensors what to do when they detect the black sumo ring line. Later on, we’ll explain the purpose of these two variables. When that happens in either case, the variable will be reset to a value of 100. The if statement checks to make sure that backTime & turnTime don’t exceed 200/500, respectively. This is so the program can keep track of how long the Sumobot has been going forward and backwards. The variables backTime and turnTime should be incremented by 1 every iteration. Next, type this in your program: backTime++
