Actually I just want to code in Python that Gelo walks..

But is there anything available like an old-school documentation (pdf?) regarding Python and Mindstorms 51515 ?

Thank you very much - I'll check this manual! Actually I've already found another solution and it works well. 

Gelo walks, stops and turns (see code below). 

I'm new to Mindstorms and coding, but am eager to hear feedback..

from random import randint

from mindstorms import MSHub, Motor, MotorPair, DistanceSensor

from mindstorms.control import wait_for_seconds, wait_until, Timer

from mindstorms.operator import equal_to

 

#Initialization

hub = MSHub()

motor_a = Motor('A')

motor_b = Motor('B')

motor_c = Motor('C')

motor_d = Motor('D')

motor_pair_1 = MotorPair('A', 'B')

motor_pair_2 = MotorPair('C', 'D')

distance_sensor = DistanceSensor('E')

timer = Timer()

power_a = 70

power_b = 70

 

#Running setting

motor_a.run_to_position(270,'shortest path', power_b)

motor_b.run_to_position(270,'shortest path', power_b)

motor_c.run_to_position(90,'shortest path', power_b)

motor_d.run_to_position(90,'shortest path', power_b)

 

#Countdown

hub.speaker.beep(60, 1)

wait_for_seconds(0.5)

hub.speaker.beep(60, 1)

wait_for_seconds(0.5)

hub.speaker.beep(60, 1)

wait_for_seconds(0.5)

hub.speaker.beep(90, 1)

 

#Running

while True:

    motor_pair_1.start(0, power_a)

    motor_pair_2.start(0, power_a)

    distance_sensor.wait_for_distance_closer_than(15, 'cm')

    motor_pair_1.stop()

    motor_pair_2.stop()

    wait_for_seconds(3)

    timer.reset()

 

    #Turning

    a = randint(0,1)

    if a == 0: #Right

        motor_a.run_to_position(140,'shortest path', power_b)

        motor_b.run_to_position(270,'shortest path', power_b)

        motor_c.run_to_position(220,'shortest path', power_b)

        motor_d.run_to_position(90,'shortest path', power_b)

        hub.motion_sensor.reset_yaw_angle()

        while hub.motion_sensor.get_yaw_angle() < 90: 

            motor_pair_1.start(0, power_a)

            motor_pair_2.start(0, power_a)

 

    else: #Left

        motor_a.run_to_position(270,'shortest path', power_b)

        motor_b.run_to_position(40,'shortest path', power_b)

        motor_c.run_to_position(90,'shortest path', power_b)

        motor_d.run_to_position(320,'shortest path', power_b)

        hub.motion_sensor.reset_yaw_angle()

        while hub.motion_sensor.get_yaw_angle() > -90: 

            motor_pair_1.start(0, power_a)

            motor_pair_2.start(0, power_a)

        

    motor_pair_1.stop()

    motor_pair_2.stop()

 

    #Running setting

    motor_a.run_to_position(270,'shortest path', power_b)

    motor_b.run_to_position(270,'shortest path', power_b)

    motor_c.run_to_position(90,'shortest path', power_b)

    motor_d.run_to_position(90,'shortest path', power_b)

    wait_for_seconds(3)

Are there good video's or text tutorials out there that explain how to add joysticks and buttons to remote control with your phone or with a controller ( I have a ps4 controller )?

Anton's page is a good start to find many things about any Mindstorms (EV3, RI, ...) He has video's/explanation about most hubs how to remote control with phone/ps4 controller.
