How to combine Road Following and Collision avoidance?

Hi All. I have recently got a Jetbot and am running a demo. Road Following and Collision avoidance can be operated separately.

I want to make a combination that stops when there is an object during Road Following. It doesn't work even if the two codes are combined, so I would like to know how you can do it.

I'm not good at English. I'm sorry if it's hard to understand.

I have finished my jetbot now and trying to run the Basic Motion notebook. I have successfully imported Robot class:

from jetbot import Robot

but when I run

robot = Robot()

Jetson Nano doesn't boot with new image

Hello, I flashed new release of pre-built JetBot SD card image for Jetson Nano 4GB (jetbot-043_nano-4gb-jp45.zip) and it doesn't boot. I read issue #385 and tried to boot with original nvidia image but it doesn't boot again and I have no Nvidia logo displayed. After that none of my different versions images don't boot . Before this incident my Jetson Nano had worked correctly. How to back my Jetson Nano to work?

Raspberry camera module V1.3 compatibility?

Hi,

I'm trying to get a camera module V1.3 working and struggling a little bit right now. The camera isn't showing up as '/dev/video0'. I'm using the default Jetson image (not the one specific to the jetbot project). I was wondering, are there specific packages I should install to make this work? Does the Jetson only work with the camera module V2?

[SOLUTION] Road Following not working properly Problem Solution

Hi guys. It is my first time talking to people on githubs. As I have got lots of help from github, I would like to share my case how I made it to work.

When I followed the instructions in Road following of Jetbot curriculum ,it couldn't get information as fast as the robot goes. I found out that the process of robot is little bit slow. Then I tried to go slooooowly and another problem has occurred. The motor provided was not strong enough to go slowly. (not enough Toque problem)

And we tried to go and stop to manage the speed. (if there were imu in it, we could control the robot with the pid or other feedback control but ,,, no) And here below is the code for the 'go and stop' .

Anyone who wants to check if the data collected works fine or not, you can try to move the robot really slow with this code, and check for the deep-learning trained model.

angle = 0.0
angle_last = 0.0
count_motor = 0
def execute(change):
    global angle, angle_last, count_motor
    image = change['new']
    xy = model(preprocess(image)).detach().float().cpu().numpy().flatten()
    x = xy[0]
    y = (0.5 - xy[1]) / 2.0
    
    x_slider.value = x
    y_slider.value = y
    
    speed_slider.value = speed_gain_slider.value
    
    angle = np.arctan2(x, y)
    pid = angle * steering_gain_slider.value + (angle - angle_last) * steering_dgain_slider.value
    angle_last = angle
    
    steering_slider.value = pid + steering_bias_slider.value
   
    if count_motor >2:
        robot.left_motor.value = max(min(speed_slider.value + steering_slider.value, 1.0)*0.95, 0.0)
        robot.right_motor.value = max(min(speed_slider.value - steering_slider.value, 1.0), 0.0)
        count_motor = 0
    else :
        robot.left_motor.value = 0
        robot.right_motor.value = 0
        count_motor = count_motor + 1

        
execute({'new': camera.value})

Gain value :


speed_gain_slider = ipywidgets.FloatSlider(min=0.25, max=1.0, step=0.01, description='speed gain')
steering_gain_slider = ipywidgets.FloatSlider(min=0.0, max=1.0, step=0.01, value=0.05, description='steering gain')
steering_dgain_slider = ipywidgets.FloatSlider(min=0.0, max=0.5, step=0.001, value=0.0, description='steering kd')
steering_bias_slider = ipywidgets.FloatSlider(min=-0.3, max=0.3, step=0.01, value=0.0, description='steering bias')

Suggestion on improving JetBot/Jetson Nano performance

Hi All,

I have recently got a JetBot kit and was able to get assembled and software installed. The examples run fine, but just seem a bit too sluggish compared to the videos linked in the Github Examples page.

For reference, I followed the instruction from https://github.com/NVIDIA-AI-IOT/jetbot/wiki/software-setup and setup everything using the jetbot_image_v0p4p0.zip.

However, I am not sure if it is the Jupyter Lab/Notebook which are slow or my routers or something with the JetBot, it just seems like there is significant delay (~1 second) in the camera video stream and also the control responsiveness of the JetBot.

Consequently, it is unable to avoid obstacles reliably, nor track an object reliably. For obstacle avoidance, it often bumps into the obstacles first, then react 1-2 seconds later and starts turning left. For object tracking, the gain had to be tuned to be much lower in order to avoid overshoot.

Therefore, I was wondering if there is anything I can try to help improve the performance of the JetBot / Jetson Nano. Any advice or suggestions is appreciated.

Jupyter fails to initialize camera...most of the times

I have assembled my jetbot with all the recommended hardware, including a Raspberry Pi Camera V2. The jetbot works and I have been able to follow the examples provided. Unfortunately, most of the times the camera is needed, the notebook fails to activate it. The instruction that creates trouble is "camera = Camera.instance()". When I try to run this cell, jupyter enters Busy mode and never proceeds. This is true most of the times. Sometimes the instance is created successfully and I am able to proceed. This is also true after a fresh reboot. Any suggestions as to what might be wrong?

Some of the links to buy the parts to build it are down or invalid (For amazon)

Hey sorry this is probably not the right place to ask this question and its stupid, but I couldn't find anywhere else to find the products or substitutes. I am very late to finding out about this, but it's cool and I was hoping to build it once I can find substitutes for part links are updated. Thanks!

Locked Out of Jetbot

The first time I opened the jetbot I was prompted to set up a password, which I did not do. Then the device went into sleep mode and when I try to open it again it is locked and requires a password. I tried some default passwords I found online such as "ubuntu", "nvidia" and "jetbot" but non of them worked.

Any ideas on how to solve it?
