The Tello has a low level protocol that allows you to take pictures. This flow sends the take picture command and receives / reconstructs the picture data from the Tello. Then it calls the Watson Visual Recognition service to classify what is in the image.
Use an ethernet cable to hardwire your laptop to your network so that it can reach the Internet. Connect over WiFi to the Tello drone.
- Log into IBM Cloud
- Create a Watson Visual Recognition service
- Returned to the IBM Cloud Resources Dashboard
- Click on your Watson Visual Recognition instance
- Copy the Watson Visual Recognition API key to your clipboard.
- Return to your Node-RED browser window
- Recall that in Setup / Part 2 you installed the node-red-node-watson nodes which provide a collection of Node-RED nodes for IBM Watson services
- Import the solution flow
- Double-click on the visual recognition node
- Paste the API key from the clipboard into the Visual Recognition node
- Click on the Done button
- See screenshot:
There is a solution flow available if you need help or want to check your solution.
Launch the Node-RED Dashboard by turning to the Dashboard tab in the right menu and then click on the launch button.
