""" This is a gesture for Touchbot II that does physical clicks
WARNING: The robot needs to already have the correct fingertips installed on
the fingers you plan to click with! If this is not the case you may cause
permanent damage to the robot!
This gesture tells the robot to do a physical click at the location you
specify with the fingers you choose. The command line arguments are as follow:
The point/position at which to click in the following format
x, y coordinates in the range from 0.0->1.0
angle in degrees
finger distance in mm that specifies how far apart the hand should open
Which fingers the robot should use to click
Top right, Top Left, Bottom Left, Bottom Right
For a one finger click near the bottom of the pad
python 0.5 0.9 45 20 0 1 0 0
# Parse the command line arguments
device = Device(sys.argv[1])
pos = PositionArg(*[float(v) for v in sys.argv[2:6]])
fingers = [int(arg) for arg in sys.argv[6:10]]
