Continuous Servo control Python

[Avainium]

Hi,

Im building a robot and want to write a programm so it can drive. Since I'm really unexperienced with programming I'm asking for some help. I have two continuous Servomotors and want to make them work. I've taken this as an example:

 

#!/usr/bin/env python

# -*- coding: utf-8 -*-

 

HOST = "localhost"

PORT = 4223

UID = "XXYYZZ" # Change XXYYZZ to the UID of your Servo Brick

 

from tinkerforge.ip_connection import IPConnection

from tinkerforge.brick_servo import BrickServo

 

# Use position reached callback to swing back and forth

def cb_position_reached(servo_num, position):

    if position == 9000:

        print('Position: 90°, going to -90°')

        servo.set_position(servo_num, -9000)

    elif position == -9000:

        print('Position: -90°, going to 90°')

        servo.set_position(servo_num, 9000)

    else:

        print('Error') # Can only happen if another program sets position

 

if __name__ == "__main__":

    ipcon = IPConnection() # Create IP connection

    servo = BrickServo(UID, ipcon) # Create device object

 

    ipcon.connect(HOST, PORT) # Connect to brickd

    # Don't use device before ipcon is connected

 

    # Register position reached callback to function cb_position_reached

    servo.register_callback(servo.CALLBACK_POSITION_REACHED, cb_position_reached)

 

    # Enable position reached callback

    servo.enable_position_reached_callback()

 

    # Set velocity to 100°/s. This has to be smaller or equal to the

    # maximum velocity of the servo you are using, otherwise the position

    # reached callback will be called too early

    servo.set_velocity(0, 10000)

    servo.set_position(0, 9000)

    servo.enable(0)

 

    raw_input("Press key to exit\n") # Use input() in Python 3

    servo.disable(0)

    ipcon.disconnect()

 

I don't know what to type in for ipconnection and i don't think I need the position stuff. I only want it to accelerate and slow down again. How can I do that?
