System image installation and backup

OriginBot does not have a system installed when it leaves the factory. You can install it in the following ways:

If you want to back up the current system image during use, you can refer to the following instructions to back it up yourself. The image after backup can still be used for the above burning method.

Burn the OriginBot SD card image

Download the OriginBot SD card image

Please download the SD card image of the robot from the table below and extract the downloaded file.

（5）The progress bar will display the current burning progress, and after the burning is completed, you can exit the software.

Start OriginBot

(1) Confirm that the robot kit has been installed correctly and the corresponding version system has been successfully installed, then insert the SD card and start the power;

(2) Use the network cable in the kit to connect the robot to the network port of RDK X5;

Info

The RDK X5 wired network uses a static IP configuration by default, and the initial IP address is 192.168.127.10.

(3) Connect the other end of the network cable to the network port on the PC. First, configure your computer properties. Take RDK X5 as an example: image-1726223687817 image-1726223701019

(4)Start the MoboXterm software, click Session in the upper left corner, and then click SSH connection: 1726223618546

(5) In the MoboXterm software, you can see a login prompt. Enter the username and password. Both the username and password are root: image-20220902150943452

(6) At this point, you have successfully entered the robot's system: image-20220902151620051

Expand SD card space

In order to reduce the size of the system image and facilitate downloading and burning, the free space in the system image has been compressed. If you need to use the full space of the SD card, you need to expand it manually.

After starting OriginBot and logging in via wireless connection, you can use the following command to expand:

#If V3.x is used, run the following command
sudo growpart /dev/mmcblk2 2
sudo resize2fs /dev/mmcblk2p2

After the operation is successful, restart the system to take effect. Use the following command to confirm that the system space expansion is successful. The SD card used here is 32GB:

CWireless WIFI connection introduction

After completing the Ubuntu installation, start the system and refer to the following link to complete the wireless network configuration:

sudo nmcli device wifi rescan        # Scan wifi networks
sudo nmcli device wifi list          # List the Wi-Fi networks found
sudo wifi_connect "SSID" "PASSWD"    # Connect to a specified wifi network

image-20220902152042941

When the terminal returns the message "successfully activated", it means that the WIFI connection is successful. We can ping a website to check the connection. If it can be pinged, it means that the network has been successfully connected. Now you can successfully connect to the Internet, which is convenient for subsequent software downloads and updates.

SSH telnet

After the network configuration is completed, you will no longer be restricted by cables, and you can remotely log in to the robot through the wireless network to carry out development.

Info

Here, fill in the corresponding IP address according to whether you are using a wired network or a wireless network. The IP address can be queried using the ifconfig command. eth0 corresponds to the wired network card, and wlan0 corresponds to the wireless network card.

Enter the username and password: root/root, and you can log in successfully:

Info

  • If you are in the Ubuntu environment on the PC side, you can also use the following command to implement ssh remote login in the terminal (note to change the IP address to the actual address): ssh root@192.168.31.246

  • If you're using a virtual machine, set the network to bridging mode

Back up the OriginBot SD card image

The following backup process is done on the Ubuntu system on the computer.

Compress disk space

In order to reduce the image size, we first use gparted software to compress the disk space of the SD card. Insert the SD card into the running computer, install and launch the gparted software:

sudo apt-get install gparted
sudo gparted

In the open gparted software, select the SD card in the upper right corner: img

Then right-click and select Mount Unmount SD Card: img

Go ahead and right-click, select the "Resize/Moves" option to reset the space on your SD card: img

Drag the right side of the space partition bar, compress the space, where yellow is the occupied partition, white is the free partition, pay attention to keep a little white free partition to avoid the image cannot be started. img

After confirmation, click the execute button in the software to start the compression operation. img

Once the compression is complete, you can close the gparted software.

View disk information

Open the terminal and run the fdisk command to view the current disk status.

sudo fdisk -u -l
img

In the figure, /dev/sdb is the disk number of the SD card, run the following command to view the partition information of the SD card:

sudo fdisk -u -l /dev/sdb
img

Start the backup-to-disk

Now you can use the dd command to back up your SD card to an img file.

sudo dd bs=512 count=[fdisk command maximum end number + 1] if=/dev/sdb of=originbot_backup.img
img

At this time, there is no message in the terminal, but the backup has started and it will take a long time, so please wait patiently.

After the backup is completed, the terminal command will automatically pop up, and the img image backup file will be obtained in the current path. img

The generated IMG image file is large, and if necessary, you can continue to use zip and other tools for compression and decompression.

At this point, the SD card image has been backed up, and when you need to use it, you can refer to Burn the OriginBot SD card image.
