Responding to User Interaction via Light

This example will allow Spot to respond to a light shining in its front left camera. The following describes what to expect:

  • with the robot sitting, shine a light into the front left camera, Spot should stand up

  • shine a light into the front left camera again, Spot should start tilting to follow the light

  • remove the light, Spot should sit down

NOTE: Both the light detection and controller are very crude. One needs to have a very steady hand to prevent the robot from “seeing” other bright lights in the front left camera.

Setup Dependencies

See the requirements.txt file for a list of python dependencies which can be installed with pip using the command:

python3 -m pip install -r requirements.txt

Run the Example

To run the example:

python3 spot_light.py --username USER --password PASSWORD ROBOT_IP

E-Stop Endpoint Dependency

The example depends on an external E-Stop endpoint application to configure E-Stop and cut off power to all motors in the robot, if necessary. In parallel with this example, please run the E-Stop SDK example as the E-Stop controller.
