The signal light on the top of TinySurveyor provides the robot's status information.
| Color | Description |
| The robot is operating without any errors and the GNSS signal is good. | |

|
The robot is operating without any errors, but the GNSS signal is weaker. The robot can still be used for marking. |
| Operation stopped because of an error (the error message is shown in the TinySurveyor app) or an overly weak GNSS signal. The GNSS signal can often be retrieved, and automatic driving will continue. | |
| The robot has received a command from the user and has begun executing it. The light also briefly turns blue when the robot has finished a job. |
