Later on I might add hotkey support or create a separate module. See 55 for details. This is a bit more complicated than the rest of the features, so I saved it for last. Luckily the code is already there, I just need to write the bindings, and I've already started. Subscribe to 13 for updates. We've been implementing keys as we need them. Feel free to create an issue or submit a pull request! The library doesn't have explicit multi-monitor support, so anything that works is kind of on accident.

Subscribe to 88 for updates. For any other questions please submit an issue. I'm a huge fan of AutoHotkeyand I've used it for a very long time. AutoHotkey is great for automation and it can do a bunch of things that are very difficult in other languages.

For example, it's imagesearch and pixel related functions are hard to reproduce on Mac, especially in scripting languages. These functions are great for automating apps that can't be automated like Netflix. This has never been a big deal since I've always used Windows at work, but for the past few years I've been using Mac exclusively.

I like AutoHotkey, but I like Node. Based on autopy.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

As somebody who is spending the majority of his time programming in JavaScript, what's the best route to get into small-robotics without needing to deviate too much from my current language focus? Are there any project kits or tools that make use of the JavaScript language that might make the field more approachable for developers like myself?

I would even be interested in virtual environments where all code is executed in a simulation. There are a couple of projects out there that mate the Arduino platform to the Node. Take a look at Johnny-Fivewhich is a library on top of the Arduino Firmata remote control protocol or node-reflectawhich is a Node. I've personally built a Node. Hmm, interesting question! I personally would suggest that you take a look at the Arduino platform.

It's programmed in C, so the syntax is going to be I'm not saying that you're just gonna drop some JavaScript code into it and be on your way, but I was a JavaScript programmer when I started out with Arduino, and I found it quite easy to pick up and run with.

Good luck, as a part time teacher in robotics it's always awesome to see people getting into the field! Specifically you will want to look at rosbridge. You will then need to use rosserial to interface with the microcontroller controlling your robot.

You would be better served to pick up an Arduino and learning a little bit of C. Arduino does a great job of making the process simple and C is not a large deviation from JS from a syntax perspective. Generally there are many ways to use node. There are a lot more similar ones if you just search for them.

Another interesting one is ArduGatewhich lets web pages communicate with the arduino via JS though probably not exactly what you wanted since it doesn't compile and load to the arduino.

Though I really don't see what's wrong with using a different language. Remember, we're not needing anything fancy for programming a robot--just normal if s, for s, while s, switch es, and the occasional class. One advantage of using the native languages is that it's much easier to find APIs and example code on the net.

So, unless you want to stick to simple programs, it's just better to use the native languages. A friend of mine actually has a pretty powerful tank robot that's controlled with NodeJS over wifi. The robot itself isn't exactly "small-robotics" at pounds, but you could probably learn quite a bit from the source code.

It has a netbook onboard running a webserver and talking to an Arduino. You can find the source code on his Github project page. The real-time control from a web browser on another computer is surprisingly responsive. Microsoft Robotics uses a protocol called Decentralized Software Services Protocol DSSP and they released the specs under a license that allows anyone to implement it in any language.

That can make it possible for your node application to interact with any DSS robotics services available today.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

For security reasons, it is recommended that you always explicitly specify the window and domain you want to listen to and send messages to.

This creates a secure message channel that only works between two windows on the specified domain:. The function user.

Post Robot transparently messages back to the original window, calls the function that was passed, then messages back with the result of the function.

Use WeakMap to get references by window. Apr 2, Jan 23, Improve clean up window message.You may see some commands labeled "Beta" or "Alpha" because the related hardware, firmware, or software is still under development.

Feel free to use these commands, but realize they may behave unpredictably at this time. Misty comes with a set of default images that you can display onscreen and sounds that you can play through her speakers. We encourage you to get creative and use your own image and audio assets in your skills.

Enables you to remove an audio file from Misty that you have previously saved. Note: You can only delete audio files that you have saved to Misty. You cannot remove Misty's default system audio files. Note: You can only delete image files that you have previously saved to Misty's storage.

You cannot remove Misty's default system image files. Note: With the on-robot JavaScript API, data returned by this and other "Get" type commands must be passed into a callback function to be processed and made available for use in your skill. For more on handling data returned by "Get" type commands, see "Get" Data Callbacks.

Saves an image to Misty in the form of a byte array string. Optionally, proportionately reduces the size of the saved image. Valid image file types are. Maximum file size is 3 MB. Note: Images can be reduced in size but not enlarged. Because Misty does not adjust the proportions of images, for best results use an image with proportions similar to her screen x pixels.

Creates a property comparison test to specify which data the system sends for a registered event. Use property tests to filter unwanted data out of event messages. Use the misty.

AddReturnProperty method to add the values of specific properties from an event message to the data object passed to the callback function for the event.

When the event callback handles the data object for an event, the data object includes the values of any properties added with misty. AddReturnProperty in an array called AdditionalResults. You can add multiple return properties to the same event.

The order of values in the AdditionalResults array matches the order in which you added those properties to the event in your skill code. For an example of how this works, see how the following code adds return properties to a BumpSensor event:.

Get Started. View Project.I have created a differential drive robots simulator in Javascript. See it in action here. A differential drive robot has two wheels, that can run independently. If the two wheels go at the same speed, the robot goes straight.

If one wheel is going one way, and the other wheel is going the other way with the same speed, the robot will spin in place.

If one wheel is stopped, while the other is going, the robot will make a turn around the wheel that is stopped. R2D2 from Star Wars is an example of a differential drive robot. Many robots can share a field. The field is where the robots move. The simplest example of using the API is to create one robot with default color in the middle of the field. The width and height attributes of the canvas element, indicates the resolution of the element, but not the size.

For this API to work, always use To set the size of the canvas element, use CSS like this:. The JSRobot object constructor takes two arguments; the locationand the color.

The location argument must be an object with xand y properties. To move the robot, you can use the methods startstopand setSpeeds left, right. It is pretty obvious what startand stop are for, so I am not going to explain that.

The setSpeeds left, right methods sets the current speed in canvas units per second of the leftand right wheel.

If you set the speed of both wheels toit means that the robot will travel the entire width of the canvas in one second. To make the robot spin in place, set the left wheel speed to a negative value, and the right wheel to the same positive value. The robot only has one event; move. Every time it has moved, it will call the function that was last passed to the onMove method. The callback function has one argument locationwhich has two properties; previousand current.

Both previousand current has three properties; xyand direction. The direction property is the clockwise angle from horizontal in degrees. So if the direction is 0, it is horizontal heading to the right, if the direction isit is heading up.

The JSRobot object has a couple of convenience methods to make it easier to determine where the robot is.Using the class to generate input events differs from posting events to the AWT event queue or AWT components in that the events are generated in the platform's native input queue. For example, Robot. Note that some platforms require special privileges or extensions to access low-level input control.

If the current platform configuration does not allow input control, an AWTException will be thrown when trying to construct Robot objects. Applications that use Robot for purposes other than self-testing should handle these error conditions gracefully. Since: 1. String toString Returns a string representation of this Robot.

Throws: AWTException - if the platform configuration does not allow low-level input control. This exception is always thrown when GraphicsEnvironment.

Coordinates passed to Robot method calls like mouseMove and createScreenCapture will be interpreted as being in the same coordinate system as the specified screen. Note that depending on the platform configuration, multiple screens may either: share the same coordinate system to form a combined virtual screen use different coordinate systems to act as independent screens This constructor is meant for the latter case.

If screen devices are reconfigured such that the coordinate system is affected, the behavior of existing Robot objects is undefined. Parameters: screen - A screen GraphicsDevice indicating the coordinate system the Robot will operate in.

IllegalArgumentException - if screen is not a screen GraphicsDevice. The mouse buttons should be released using the mouseRelease int method. Parameters: buttons - the Button mask; a combination of one or more mouse button masks.

It is allowed to use only a combination of valid values as a buttons parameter. A valid combination consists of InputEvent.

The valid combination also depends on a Toolkit. If support for extended mouse buttons is enabled by Java then it is allowed to use the standard button masks and masks for existing extended mouse buttons, if the mouse has more then three buttons.
