Sending data wirelessly to esp8266 NodeMCU v3 from ArduinoIDE

Question

I am working on a school project. I have to build a robot that will push the other robot off the table. the robot should have a camera and move by it self, but my teacher said that if i manage to connect xbox controller to it it will be fine.

I was given an esp8266 NodeMCU v3, Arduino uno, 2 motors, l298n motor driver and nothing else. I have writen a code in python and ArduinoIDE

void setup()
{
  pinMode(4, OUTPUT);
  pinMode(5, OUTPUT);
  pinMode(12, OUTPUT);
  pinMode(14, OUTPUT);

  Serial.begin(9600);
}

void rr(int value1, int value2)
{
  analogWrite(4, value1);
  analogWrite(5, value2);
}
void rl(int value1, int value2)
{
  analogWrite(12, value1);
  analogWrite(14, value2);
}

void loop()
{
  String read = Serial.readString();
  int power = read.toInt();

  rr(power, 0);
  rl(power, 0);
}

import pygame, sys, serial
import time

time.sleep(1.0)

ser = serial.Serial("COM5", 9600)

pygame.joystick.init()

joystick = [pygame.joystick.Joystick(x) for x in range(pygame.joystick.get_count())]
pygame.init()

clock = pygame.time.Clock()

def map_range(x, a, b, c, d):
    y = (x-a) * (d-c) / (b-a) + c
    return y
while True:
    clock.tick(60)
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            sys.exit()
    position = round(pygame.joystick.Joystick(0).get_axis(5))
    #position = 100
    ser.write(str(map_range(position, -1, 1, 0, 255)).encode("utf-8"))

I wonder if it possible to wirelessly update "power" variable so i can controll the robot speed.

I have done lots of reserch and i was not able to find anything that will work
