  1. 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?
