The ultimate node.js client for controlling Bitcraze Crazyflie 2.0 drones
There were too many outdated and undocumented node.js libraries out there for programming Crazyflies. This package's goal is to fix that.
This package assumes you have the latest version of the Crazyflie firmware.
If on a Windows machine, look on the Bitcraze wiki for instructions to install the correct driver onto your Crazyradio. You do not need to do this on macOS or Linux!
This package's main dependency is node-usb. Refer to its installation directions for any help installing it on your operating system.
$ npm install swarms
Note: On Windows, you may get errors installing the node-usb package like the following: you may fail to install the node-usb package getting errors like:
error C2011: 'timespec': 'struct' type redefinition
You can fix this by following the directions here.
The following script moves the drone's propellers. More examples are located in the /examples directory.
const { Crazyradio } = require('swarms');
const radio = new Crazyradio();
// Because you can only use `await` within an async function...
main();
async function main() {
try {
await radio.init();
const drones = await radio.findDrones();
if (drones.length < 1) {
throw 'Could not find any drones!';
}
const drone = await radio.connect(drones[0]);
await drone.commander.setpoint({
roll : 0,
yaw : 0,
pitch : 0,
thrust: 32500
});
} catch (err) {
console.log('Uh oh!', err);
await radio.close();
}
