+# Launch Instructions for VectorNav with Permission Issues
+
+This document explains how to resolve permission issues for serial devices (like `/dev/ttyUSB0`) and launch the VectorNav package on Linux.
+
+## Prerequisites
+
+1. **Install Necessary Packages**: Ensure all required packages are installed in your workspace and that the workspace is correctly sourced.
+
+2. **Device Permissions**: You’ll need permission to access the device files (e.g., `/dev/ttyUSB0`).
+
+## Steps
+
+### Step 1: Check Device Permissions
+
+1. First, identify the device port:
+   ```bash
+   ls /dev/ttyUSB*
+   ```
+2. Verify your user has permission to access the device. If you see an error or permission denied, proceed with the steps below.
+
+### Step 2: Add User to the `dialout` Group
+
+The `dialout` group typically has access to serial devices. Add your user to this group:
+
+```bash
+sudo usermod -aG dialout $USER
+```
+
+**Note**: Log out and log back in for the group change to take effect. Alternatively, you can restart the system to apply these changes immediately.
+
+### Step 3: Verify Permissions
+
+After re-logging or rebooting, check that you have read and write permissions on the device:
+
+```bash
+ls -l /dev/ttyUSB0
+```
+
+If permissions are set correctly, the output should show that `dialout` has `rw` (read/write) access for `/dev/ttyUSB0`.
+
+### Step 4: Launch VectorNav
+
+Source your ROS workspace, then launch the VectorNav nodes with the appropriate configurations:
+
+```bash
+source ~/Documents/urc/rover-colcon/install/setup.bash
+ros2 launch vectornav vectornav.launch.py
+```
+
+**Note**: Replace the workspace path with the correct path if it’s different on your system.
+
+### Troubleshooting
+
+If you continue to experience issues with permissions, consider checking `dmesg` logs to ensure the device is recognized:
+
+```bash
+dmesg | grep ttyUSB
+```
+
+This command shows messages related to the USB connection and may help diagnose connectivity issues.
