Installation

npm install monster-drift --save

Usage

Drive forward for one seconds and stop:

var drive = require('monster-drift')()

drive.forward()

setTimeout(function () {
  drive.stop()
}, 1000)

API

var drive = new MonsterDrift([options])

This module exposes a MonsterDrift object that you can initiate to get a drive object.

Options:

• stop - Milliseconds in which to automatically stop the card if no drive commands have been issued (default: never)
• freq - The frequency in Hz (default: 27MHz)
• id - The HackRF device id to use (default: 0)
• gain - The HackRF TX gain (default: 40)

drive.forward()

Drive forward.

drive.backward()

Drive backward.

drive.left()

Turn wheels left.

drive.right()

Turn wheels right.

drive.forwardRight()

Drive forward and right.

drive.forwardLeft()

Drive forward and left.

drive.backwardRight()

Drive backward and turn right.

drive.backwardLeft()

Drive backward and turn left.

drive.stop([callback])

Stop the car and turn off transmitter. Calls optional callback when done.

drive.close([callback])

Stop the car, turn off transmitter and close the HackRF USB connection. Calls optional callback when done.

drive.turn180([callback])

Make a 180. Calls callback when done.

drive.batch(commands[, callback])

Issue a series of driving commands to the car and call optional callback when done.

The commands argument is an array of commands. Each command is a double tuple with the following format: [function, duration]. The function part is a drive function, e.g. drive.forward, and the duration part is the number of milliseconds to perform the operation.

If the last tuple contains a duration then drive.stop will be called automatically. Leave out duratuon to continue forever.

// make a 180
drive.batch([
  [drive.forward, 1000],
  [drive.right, 125],
  [drive.backwardLeft, 100],
  [drive.backward]
])
