Controls dont work after new install - Mars Rover

1585597812

I just set up the a brand new mars rover and am having issue with the controls. My PC / client is connecting the to Picar but it doesnt seem to be controling it properly. The camera is streaming but I cant move it at all. The forward and back seem to work but I can stop the car once its in motion. The other controls also dont seem to work.

I am using  Rasberry Pi 4 with Buster install.

I have Python 3.7 with all packadges installed using 37 as well.

I do get this below error when connecting the IP on the client. Not sure if its related.


C:\Users\Yoel Felberbaum\Desktop\Silky\Adeept_PiCar-B-V1.0\code\Adeept_PiCar-B-master\client\client.py:55: DeprecationWarning: The binary mode of fromstring isdeprecated, as it behaves surprisingly on unicode inputs. Use frombuffer instead


npimg = np.fromstring(img, dtype=np.uint8)

THe LED on the car is always blue, I am able to connect to it via putty and via Client. Any pointers here would be appriciated. I tried everything, using Python 3.8, reinstalling the OS and software on the car. I must be doing something obvious wrong, I just donw know what.

Hello,

Please run server.py manually on the Raspberry Pi, and then run the client program on the computer to connect to the server and operate the car, and observe if the server reports an error.

Best!

Hi,

So I went back and recreated my steps. I did a manual server install, had to make the following changes to get the server.py to run


So first there is an issue with the latest version of open opencv-python version 4.1.1.26

I got the below error

sudo python3.7 Adeept_PiCar-B/server/server.py
Traceback (most recent call last):
  File "Adeept_PiCar-B/server/server.py", line 15, in <module>
    import FPV
  File "/home/pi/Adeept_PiCar-B/server/FPV.py", line 10, in <module>
    import cv2
  File "/usr/local/lib/python3.7/dist-packages/cv2/__init__.py", line 3, in <module>
    from .cv2 import *
ImportError: /usr/local/lib/python3.7/dist-packages/cv2/cv2.cpython-37m-arm-linux-gnueabihf.so: undefined symbol: __atomic_fetch_add_8

TO RESOLVE I DID THE FOLLOWING

1. sudo pip3 uninstall opencv-python

Copy the Code

1. sudo pip3 install opencv-contrib-python==4.1.0.25

Copy the Code

This then left me with another issues

sudo python3.7 Adeept_PiCar-B/server/server.py
Traceback (most recent call last):
  File "Adeept_PiCar-B/server/server.py", line 23, in <module>
    from mpu6050 import mpu6050
ModuleNotFoundError: No module named 'mpu6050'

TO RESOLVE I DID THIS

1. sudo pip3 install mpu6050-raspberrypi

Copy the Code

Next post is my error

The server completely ignores the stop command

I also get this on the client side, not sure if its related.

My environment

Raspberry Pi  4-B

The error reported in this place, not a software problem. The stop command is issued after the user releases the key

Dear 1585597812, dear Lina,

I have exactly the same issue:
I tested the client.py on Windows 10 (and Linux). The video stream is working. The buttons "forward" and "backward" are working. However, ALL other buttons are not working. Particularly, the "stop" button is not working, s.t., the PiCar is just driving forward or backward until it hits a wall.

Hence, the PiCar is useless right now.

Did you find any solution for the problem?

I am looking forward to your advice.

Same issue here. I am going to do a manual install to see if I can spot any issues., Currently updating the OS

The program is newly updated on github. The new version of the document has introduced how to run webServer.py.
