Before beginning these steps ensure that your setup meets this criteria:
- VEX AI License Key is plugged in the Jetson.
- VEX AI Intel Camera is plugged in the Jetson.
- VEX AI FLIR Camera is plugged in the Jetson.
- SD card is inserted in the Jetson.
- Jetson was rebooted after plugging in all devices (if the Jetson was turned on during devices being plugged in).
- Your VEX AI System is up to date.
Accessing the Dashboard of the VEX AI Intel Camera gives you insight into where the robot is on the field as well as what game pieces are in front of it.
To begin, on your computer, open the WIFI settings and select ‘VEX_AI.’
A password will be required.
The password is ‘vexrobotics.’
Once connected, open your preferred internet browser and go to the url 10.10.0.1. This will take you to the web server.
On the web page, you will see the camera view from the Intel camera and information about the position of the robot. As the robot moves, the feed from the camera will update in real time.
On the map feed you will notice arrows on the left and bottom of the field image. The arrow on the left indicates the Y value of the robot's location. The arrow on the bottom indicates the X position of the robot. Both values are shown in the units of inches from the center point of the field. The image below shows how the X and Y grid is laid out on the field.
Also the robot image is oriented the same as the real robot. The heading is displayed in degrees on the front of the robot.
On the video feed, the detected objects information is overlaid on the video. Each object that is detected by the system will have the following information:
- Pixel location of the center of the object (X,Y). The location is referenced from the top left corner of the image.
- Distance from the robot to the object in inches. This distance is from the AI Depth camera to the object.
- Width and Height of the detected object in pixels. This is displayed as the box that is drawn over the object on the image.
- Classification of the object. The system will classify detected objects as either a red ball, a blue ball or a goal. This classification is displayed on top of the bounding box that is drawn over the object. And by the color of the bounding box itself.
Note: Goals can only be detected if the camera can see the green vision target on top of the goal.
