DESCRIPTION:

A ruby gem for controlling your Sphero ball. Sends commands over the TTY provided by the bluetooth connection.

FEATURES/PROBLEMS:

• You need a Sphero

SYNOPSIS:

You can easily start your Sphero and send it commands like this:

Sphero.start '/dev/tty.Sphero-YBW-RN-SPP' do
	roll 60, FORWARD
	keep_going 3

	roll 60, RIGHT
	keep_going 3

	roll 60, BACKWARD
	keep_going 3

	roll 60, LEFT
	keep_going 3

	stop
end

Here is another example:

Sphero.start "/dev/tty.Sphero-PRG-RN-SPP" do
	ping

	# Roll 0 degrees, speed 125
	roll(125, 0)

	# Turn 360 degrees, 30 degrees at a time
	0.step(360, 30) { |h|
  	h = 0 if h == 360

		# Set the heading to h degrees
 		heading = h
 		keep_going 1
	}

	keep_going 1
	stop
end

Here is a another way to do the same thing as the previos example, via just normal method calls instead of the DSL:

s = Sphero.new "/dev/tty.Sphero-PRG-RN-SPP"
s.ping

# Roll 0 degrees, speed 125
s.roll(125, 0)

# Turn 360 degrees, 30 degrees at a time
0.step(360, 30) { |h|
  h = 0 if h == 360

  # Set the heading to h degrees
  s.heading = h
  sleep 1
}
sleep 1
s.stop

Pairing sphero with ubuntu

Add your user to the dialout group

$ sudo usermod -a -G dialout <user>

Then logout or restart your computer. Once your user is logged back in, pair the sphero with the ubuntu bluetooth manager.

Once paired, you may now bind your sphero to a rfcomm port

$ sudo hcitool scan 
Scanning ...
<address>		Sphero
$ sudo rfcomm bind /dev/rfcomm0 <address> 1

You may now access the sphero from /dev/rfcomm0

REQUIREMENTS:

• A Sphero ball connected to your computer
• Supports MRI 1.9.2/1.9.3 and Rubinius 2.0rc1 for sure...

INSTALL:

• gem install sphero
