功能

• Description
• The SparkFun Advanced Autonomous Kit for Sphero RVR(pronounced "Rover")provides all the functionality of the basic kit with the addition of time-of-flight distance sensing in the front and rear. Based around Raspberry Pi's small yet powerful Zero W model, the kit provides distance sensing, global positioning, and vision to the Sphero RVR.
• A pan-tilt device allows a camera to not only provide video from the viewpoint of the RVR, but provide the ability to look around it as well. In addition, the Raspberry Pi Zero W and the Camera provide enough power to run most of the machine vision programs that will run on the Raspberry Pi platform.
• The Qwiic distance sensing boards use time-of-flight technology to provide highly accurate distance sensing for things like collision and obstacle detection. The GPS board provides global position capabilities to the RVR. Whether you're setting up a geofence which the RVR must stay inside or mapping where the RVR has been, the board has the accuracy and capability to work for a small object such as the RVR. Pair these items with the already stellar sensor set of the RVR and the device has an advanced set of sensing abilities for autonomous mobility.
• The kit itself comes with all the cables and mounting hardware including a separate mounting plate that provides extra space for mounting additional sensors or devices such as SparkFun's Qwiic line, which pairs with the rest of the devices with ease.
• Note:A Sphero RVR is
