  • PX4FLOW Smart Camera PX4FLOW is an optical flow smart camera. It has a native resolution of 752x480 pixels and calculates optical flow on a 4x binned and cropped area at 400 Hz, giving it a very high light sensitivity. Unlike many mouse sensors, it also works indoors and in low outdoor light conditions without the need for an illumination LED. Apr 05, 2018 · PX4flow and TFmini facing down. LED added on day 2. Lipo mounted transverse with Dual Lock. 5V supply from regulator on pins 2 and 3. Serial connection to Pixhawk on 4/5 and gnd. Configuration. The main challenge was to convert the system for indoor use. The GPS was replaced with a PX4flow and the Arducopter parameters configured accordingly.
  • Introduction. This tutorials shows how to config Pixhawk to integrate in an AGV. It permits to get information of the device (IMU and gyroscope) througth MAVLINK protocol using the package mavros. ZED cameras perceive the world in three dimensions. Using binocular vision, the cameras can tell how far objects are around you from 0.1 to 20m, indoors and outdoors. With the ZED, capture a 3D map of your environment in seconds. The mesh can be used for real-time obstacle avoidance, visual effects or world-scale AR.

The Raspberry Pi's I2C pins are an extremely useful way to talk to many different types of external peripheral; from the MCP23017 digital IO expander, to a connected ATmega. The I2C pins include a fixed 1.8 kohms pull-up resistor to 3.3v. This means they are not suitable for use as general purpose IO where a pull-up is not required.
