This uses WebSockets in the browser to connect to a mirobot on your local WiFi.
First download this repository as a ZIP and extract it into a folder in your Documents or Desktop.
The simplest way to use mirobot locally is with the Chrome app:
https://chrome.google.com/webstore/detail/mirobot/bjkfmkklaabeoomedlpgfplgndpiijea
First turn the mirobot on and connect to its WiFi, then in the Mirobot apps connect to the following IP:
local.mirobot.io
If for some reason you don't want to use the Chrome App, you can still locally run the apps.mirobot.io site:
First turn the mirobot on and connect to its WiFi.
Then cd or open the apps.mirobot.io/ folder in your Terminal:
cd apps.mirobot.ioNow you need to start a local server, you can do this with Python like so:
python -m SimpleHTTPServerOr in Node.js + npm if you have that setup:
# first install serve globally (just do this once)
npm install serve -g
# then you can always serve this folder
serve .Now you can use the apps as usual, but connect to the following IP within the apps:
local.mirobot.ioLet's say you want something really advanced, like connecting Face Tracking or some other cool JavaScript-based app to your Mirobot.
For this you can use my simple websockets/ interface:
- Turn the mirobot on.
- Connect your computer to its WiFi.
- Open up
websockets/move.htmlHTML page within the repository folder. Use Chrome or FireFox to open it. - The bot should start moving! Open the DevTools console so you can see the messages sent and received.
Here's an example script that draws a rectangle:
const bot = mirobot();
// Send a 'stop' to kill any previously running commands
bot.stop();
// draw a square
bot.pendown();
bot.forward(250);
bot.left(90);
bot.forward(250);
bot.left(90);
bot.forward(250);
bot.left(90);
bot.forward(250);
bot.penup();
// beep for 250 milliseconds
bot.beep(250);The code goes inside an HTML page, like this:
<html>
<body>
<p>hello world</p>
<!-- Include the mirobot.js library -->
<script src='mirobot.js'></script>
<!-- Now you can run your code -->
<script>
.. YOUR MIROBOT CODE HERE ..
</script>
</body>
</html>The mirobot() function also takes an ip address if you want to connect to something other than local.mirobot.io, e.g. if you want to use the internet to drive your robot.
const bot = mirobot('192.168.2.10');
...e.g. Hooking up with webcam or microphone you might want to use bot.idle, bot.reset(), and others.
const bot = mirobot();
// handle colliders
bot.enableCollisionListener();
bot.collision(state => {
console.log(state); // left, right or both
bot.beep(250); // beep on collision
});
// A 1-second event loop for the robot
setInterval(() => {
bot.reset(); // clear command queue
bot.stop(); // stop movement
bot.forward(Math.random() * 250); // move randomly
}, 1000);
// A 24 frames per second loop for sensors
// e.g. microphone or webcam input
setInterval(() => {
if (bot.idle) { // if bot is idling
const sensorData = /* get sensor data */;
// move based on sensor data...
bot.left(sensorData);
}
}, 1000 / 24);
