SSH Connection to the cloud from the Orange Pi

Now you should be able to connect to the cloud from any computers

ssh root@ssh.openbayes.com -p 30773

Make sure to update the port "30773" to your port

Cloud Installation

# if not already present
git clone https://github.com/dora-rs/gosim-2024
cd gosim-2024
curl --proto '=https' --tlsv1.2 -sSf https://raw.githubusercontent.com/dora-rs/dora/main/install.sh | bash -s -- --tag v0.3.7rc0

source ~/.bashrc

Testing Hardware

Testing cameras

## Within the orangepi
ls /dev/video*

If you connected 2 cameras properly, this should return

/dev/video0  /dev/video1 /dev/video2  /dev/video3

Testing car

Run:

## Within the orangepi
robot

If the installation is successful, you should get:

Error: env variable DORA_NODE_CONFIG must be set. Are you sure your using `dora start`?

Caused by:
    environment variable not found

Location:
    /home/HwHiAiUser/.cargo/registry/src/index.crates.io-6f17d22bba15001f/dora-node-api-0.3.6/src/node/mod.rs:67:57

If not you should try:

sudo chmod 777 /dev/ttyUSB0

If you get serial connect fail means that there is a problem with the board.
