The Clever platform allows a [Raspberry Pi](raspberry.md) computer to be used for programming autonomous flights. The flight program is typically written using the Python programming language. The program may [receive telemetry data](simple_offboard.md#get_telemetry) (which includes battery data, attitude, position, and other parameters) and send commands like: [fly to a point in space](simple_offboard.md#navigate), [set attitude](simple_offboard.md#set_attitude), [set angular rates](simple_offboard.md#set_rates), and others.

The platform utilizes the [ROS framework](ros.md), which allows the user program to communicate with the Clever services that are running as a `clever` systemd daemon. The [MAVROS](mavros.md) package is used to interact with the flight controller.

PX4 uses [OFFBOARD mode](modes.md#auto) for autonomous flights. The Clever API can be used to transition the drone to this flight mode automatically. If you need to interrupt the autonomous flight, use your flight mode stick on your RC controller to transition to any other flight mode.

## Positioning system {#positioning}
A drone has to use a positioning system to be able to hover still or to fly from point to point. The system should compute the drone position and feed this data into the flight controller. Clever allows using multiple positioning systems, such as [optical flow](optical_flow.md) (requires a [camera](camera.md) and a [rangefinder](laser.md)), [fiducial markers](aruco.md) (requires a camera and markers), GPS and others.
