Several extensions have been created to support the NXT and EV3. Scratch is a very popular visually programming environment. Extensive documentation and online support is available.
#PROGRAMMING IN ROBOTC SOFTWARE#
RobotC is a C-based programming language with a fully integrated software debugger that supports a range of different hardware platforms. This is done with the assistance of the Microsoft Visual Studio Code. There is also an EV3 Animal Rescue Book that teachers might find they can use with their students.ĮV3Python helps users familiar with Python programming to use this language to control an EV3 robot. In Swift Playground, users can program robots, gather information through sensors, and cause actions via the motos. Swift Playgrounds is an iPad-only environment designed to help users learn to program using the Swift programming language. MakeCode uses blocks (like Scratch) or JavaScript (text) programming. Being able to use MakeCode on various devices might make it an attractive option. Microsoft MakeCode is an online programming platform that can control the EV3 and other devices, such as Cue and the BBC micro:bit. Whether you’re looking for a way to extend your students or to provide a link with another programming language, here is a list of some of the most popular third-party alternatives. For example, one option is to use a text-based programming language, such as RobotC, that better reflects the dominant style of programming in the computer industry.
#PROGRAMMING IN ROBOTC CODE#
Would be good to add some comments to your code as well for clarity.For anyone getting started with LEGO MINDSTORMS, the EV3 Software provides a great introduction to programming, but sooner or later you and your students might be ready for something different. You also have a typo at the top when you declare: int callown You can do the same for the following code as well: startMotor(mainMotor, 60) Īlso it seems like the while loop will never end because the value of x never changes. Here I'd write a function like the following: void adjust_sensors( size_t led, size_t level ) This is repeated with slightly different values. So in the large function called motors you have the following set of operations: int x = 1 The following code snippets I would make into separate functions. I'm not familiar with RobotC or VEX, however I've noticed a certain amount of replicated operations that could be made into their own functions. I do not know if it was a requirement for you. It does not store up and down call while it is moving and go there later. Note : in this code the elevator will only take care of new up and down floor calls when the elevator is idle.

we check if we trigger a floor switch and stop the elevator we check if a button is pressed and possibly go up or down Now, if we translate this into some pseudo code (which should be easily translated to RobotC) : enum elevator_status = The elevator is at a given floor and go from one floor to the other when it trigger a switch: Let's define what are the states of an elevator at a given moment: If (calldown = 1 & floorat = 1 & calldown = 0 || calldown = 1 & floorat = 1)Īlthough it shouldn't be a concern for this question, the 60 in the startMotor command is the speed of the motor, just to make it clearer. If (callup = 1 & floorat = 1 & calldown = 0 || callup = 1 & floorat = 1 & callup = 0) If (SensorValue = 1 & floorat = 1)Įlse if (callup = 1 & floorat = 1) When the shaft sticking out the motor mechanism moves up and down, it presses limit switches and causes it to return a value of 1.

The motor (mainMotor) rotates the gear which causes the mechanism to travel upwards on the slide. ) are analog buttons and return a value of 0 if not pressed and 1 if pressed. Could I possibly do anything to make this any simpler? Or better? I have attached a picture of my design that I made in AutoCAD Inventor with labels.įor those not familiar with RobotC or VEX (it is VERY similar to C and C++): the limit switches (limit1, limit2. I'm designing and programming an elevator-like robot for a high school project.
