this is my solution, but with a secon button to stop the robot.


#!/usr/bin/env python
from BrickPi import *
BrickPiSetup()
BrickPi.MotorEnable[PORT_A] = 1
BrickPi.MotorEnable[PORT_D] = 1
BrickPi.SensorType[PORT_4] = TYPE_SENSOR_ULTRASONIC_CONT
BrickPi.SensorType[PORT_1] = TYPE_SENSOR_TOUCH
BrickPi.SensorType[PORT_3] = TYPE_SENSOR_TOUCH
BrickPiSetupSensors()
BrickPiUpdateValues()
def start():
    running = True
    while running:
        if BrickPi.Sensor[PORT_3]:
            stop()
            return stop()
        if BrickPi.Sensor[PORT_4] < 30 :
            BrickPi.MotorSpeed[PORT_A] = -200
            BrickPi.MotorSpeed[PORT_D] = 200
            ot = time.time()
            while(time.time() - ot < 0.5):
                BrickPiUpdateValues()
                time.sleep(.2)
        else:
            BrickPiUpdateValues()
            BrickPi.MotorSpeed[PORT_A] = 200
            BrickPi.MotorSpeed[PORT_D] = 200
            time.sleep(.2)
def stop():
    BrickPi.MotorSpeed[PORT_A] = 0
    BrickPi.MotorSpeed[PORT_D] = 0
while True :
    BrickPiUpdateValues()
    if BrickPi.Sensor[PORT_1]:
        start()
    time.sleep(.2)
