The Navigator is an ROV and robotics flight controller for the Raspberry Pi 4. It has an onboard IMU, compass, barometer, and ADC sensors in addition to 16 PWM outputs and quite a few serial and I2C growth ports. The Navigator is used on the BlueROV2 together with the BlueOS software program, however will also be used for a variety of robotics functions!
The Navigator is an growth board that plugs into the Raspberry Pi 4 and turns it right into a fully-featured flight controller, able to energy ROVs, USVs, drones, floor automobiles, and absolutely anything that strikes!
At its core, the Navigator is a set of inputs and outputs. It has inputs from onboard sensors, outputs to servos or velocity controllers, and expansions ports that may be linked to exterior gadgets.
Onboard, the Navigator has:
- 6-axis IMU with accelerometers and gyroscopes for orientation
- Twin three-axis magnetometers for compass heading
- Barometer for altitude in air
- 16 servo PWM channel outputs
- Present and voltage ADC inputs
- Constructed-in leak detection for two probes
- RC receiver enter (SBUS)
- RGB standing LED
Moreover, the Navigator has growth connectors obtainable, all of which comply with the Blue Robotics Connector Normal and are suitable with most trade autopilot equipment. It has the next growth ports:
- 4 serial ports
- 2 I2C ports
- 2 16-bit analog-to-digital converter (ADC) ports
- Exterior LED port suitable with Neopixel RGB LEDs
As well as, the Navigator has a variety of essential options which can be price highlighting:
- Twin energy inputs with automated energy switching for redundancy
- 3.3V logic on all ports
- 5V tolerance on serial ports
The Navigator comes with a custom-designed aluminum heatsink that matches between the Navigator and Raspberry Pi and permits the Raspberry Pi to function at excessive CPU utilization in poorly cooled environments, like inside an enclosure. There’s a slot within the Navigator board that permits you to use the Raspberry Pi’s CSI digital camera connector.
The Navigator equipment additionally comes with a set of growth cables for the serial, I2C, and ADC ports to can help you join your {hardware} rapidly and simply.
The Navigator equipment ships with an SD card loaded with BlueOS, our new core working software program for the ROVs and different robotics. Constructed on prime of Raspbian Linux, it gives a bunch of options together with autopilot software program administration, video streaming, software program updates, and user-defined extensions. It permits you to get began rapidly with the Navigator and ArduPilot firmwares.
The Navigator schematic design is open supply and obtainable that can assist you maximize your utilization of the Navigator.
Notice: The Navigator is technically not a Raspberry Pi “hat” as a result of it doesn’t meet the entire official necessities, nevertheless it really works very equally to a Raspberry Pi hat.
