For more details, please refer to the official guizero documentation at Overview - guizero
I almost got the code working but not px.forward() and px.backward(). px.forward() work but px.backward() cause one wheel to run forward and other wheel to run backward. There are textboxes next to sliders and I don’t know how to write code so that entering numbers in textboxes cause cause the sliders to move to the number that I entered.
from picarx import Picarx
import time
from guizero import *
px = Picarx()
def slider_changed1(slider_value):
textbox1.value = slider_value
number1 = int(textbox1.value)
px.set_dir_servo_angle(number1)
def slider_changed2(slider_value):
textbox2.value = slider_value
number2 = int(textbox2.value)
px.set_camera_servo1_angle(number2)
def slider_changed3(slider_value):
textbox3.value = slider_value
number3 = int(textbox3.value)
px.set_camera_servo2_angle(number3)
def slider_changed4(slider_value):
textbox4.value = slider_value
number4 = int(textbox4.value)
if number4 > 0:
px.forward(number4)
elif number4 == 0:
px.forward(0)
px.backward(0)
elif number4 < 0:
px.backward(abs(number4))
app = App(“Robot controller”, layout=“grid”)
Text(app, “Steer”, grid=[0,1])
Text(app, “Pan”, grid=[0,3])
Text(app, “Tilt”, grid=[0,5])
Text(app, “Speed”, grid=[0,7])
number1 = Slider(app,start=-60,end=60,grid=[1,1],width=300,command=slider_changed1)
number2 = Slider(app,start=-60,end=60,grid=[1,3],width=300,command=slider_changed2)
number3 = Slider(app,start=-30,end=30,grid=[1,5],width=300,command=slider_changed3)
number4 = Slider(app,start=-100,end=100,grid=[1,7],width=300,command=slider_changed4)
textbox1 = TextBox(app,grid=[2,1])
textbox2 = TextBox(app,grid=[2,3])
textbox3 = TextBox(app,grid=[2,5])
textbox4 = TextBox(app,grid=[2,7])
time. Sleep(1)
This issue we need some time to do testing, the results will be the first time to reply to you.
