Introduction

This is an AI Racing Robot kit based on Jetson Nano Developer Kit. Supports deep learning, auto line following, autonomous driving, and so on.

Notice

The Jetson Nano Developer Kit is not included in the Acce Kit, you need to buy it separately.

We do not provide batteries in the AI Kit or the Acce Package because of shipping policy, you need to buy batteries in local market.

User Guides

1. Hardware setup

2. Software setup

【Note】 The software part of this guide mostly based on NVIDIA JetRacer wiki

Step 1. Write JetRacer image to SD card

  • After writing, eject the SD card
Step 2. Startup Jetson Nano Developer Kit
  • Insert SD card to SD card slot of Jetson nano (slot is under Jetson Nano board)
  • Power on JetRacer AI Kit, and connect the micro USB interface of Jetson Nano Developer Kit to your PC

【Note】You had better test the Jetson Nano Developer Kit before you assemble JetRacer

Step 3. Connect JeRacer to WIFI

All the examples use WIFI, we need to connect JetRacer to WIFI firstly.

  • Open a browser (we recommend you to use Chrome) and navigate to 192.168.55.1:8888
  • Sign in with default password jetson
  • Open a terminal in Jupyter Lab by click File -> New -> Terminal
  • In the terminal, type the following command to list available WiFi networks, and find the ssid_name of your network. You can also skip this step if you have known the available network.
sudo nmcli device wifi list
  • Connect to the selected WIFI network. Please replace the <ssid_name> and <password> to the actual name and password.
sudo nmcli device wifi connect <ssid_name> password <password>
  • After getting the successfully information, please check the ip_addtess of Wlan0 interface by the following command
ifconfig
Step 4. Connect to JetRacer over WIFI
  • Unplug the USB cable from Jetson Nano
  • Close the previous Jupyter Lab Browser tab
  • Open a new browser tab and navigate to http://<jetracer_ip_address>:8888

3. Examples

(1) Basic motion
  • Access JetRacer by going to http://<jetracer_ip_address>:8888, navigate to ~/Notebooks/basic_motion/
  • Browse to the folder ~/jetracer/notebooks in the Jupyter Lab file browser
  • Open basic_motion.ipynb file and following the notebook

【Note】You can click icon ▶ to run codes, or select Run -> Run Select Cells. Make sure the JetRacer has enough space to run.

Note
If you get error when running the motion script, please open a new termial, resintall Adafruit-PureIO librares with following commands and try again.
sudo pip3 install --upgrade pip
sudo pip3 uninstall Adafruit-PureIO
sudo pip3 install Adafruit-PureIO
(2) Teleoperations

pip3 install Cython
pip3 install numpy torch-1.2.0a0+8554416-cp36-cp36m-linux_aarch64.whl --user
sudo reboot

Do not forget to reboot at the end.


 Answer:
Four 18650 batteries are used and the voltage of every battery is 3.7V. Generally, the voltage per battery is 4.2V when full charging. Please use batteries without a protective plate.

BTW, Power of JetRacer is down when the voltage of the whole system is similar to 9V (it is not accurate), we recommend you to charge batteries if the voltage displayed is lower than 10V.
We recommend you to use high-quality batteries like Sanyo or Panasonic.

 Answer:
The 8.4V power adapter is used to charge the batteries. DO NOT directly connect it to Jetson Nano Developer board.


 Answer:
Please make sure that you have installed the codes of Waveshare instead of NVIDIA's. The drive codes of the motor are different between Waveshare's and NVIDIA's. If you have updated the one from NVIDIA's, please remove the Jetracer folder and download ours by following step 5.
