Camera types used on agrobots: – RGB cameras – extensively used in agricultural machine vision applications for fruit/plant detection, yield prediction, segmentation tasks, disease detection, ripeness detection, weed detection and insects detection – Hyperspectral, thermal, or ultrasonic cameras – typically provide better results than conventional RGB color images – Stereoscopic cameras – provides 3D plant structure information (dimension of crops (depth information, crop height, leaf shape, leaf area etc.)) Critical factor is the camera’s resolution, which should be high enough to capture the details of the scene especially in the cases of insect and disease detection.
GPS for autonomous navigation in open-field cultivation environments Robotic data collection platform equipped with RADAR, liDAR, ultrasonic radar sensors, spectrometers, fluorometers
Light sensors – allows for the greenhouse lighting to be adjusted depending on the sun’s intensity, benefits of increasing electrical efficiency and cost savings of the entire system. Sensors for Volumetric water content (VWC), Bulk electrical conductivity (ECb), Temperature – Used to monitor soil moisture content
Machine vision camera and spectral imaging – helps growers track the growing process of their entire operation, give details on plant height, 3D leaf area, projected leaf area, digital biomass, leaf inclination, leaf area index, light penetration depth, and leaf coverage
Mobile-enabled IoT sensors, Bluetooth beacons, infrared counters or sensors embedded in the pavement, turnstiles
Portable waste bin or portable toilets enabled with GNSS. Once data related to fill rates and temperatures of smart bins /toilets are collected, the sensors relay the exact location and other waste related information of the bins in question so waste management can send out SMSes to nearby garbage collectors to do the needed collection/emptying before harmful carbon emissions are released.
Satellites: Geostationary and polar-orbiting weather satellites are equipped with advanced sensors to monitor wind patterns at high altitudes globally. They are particularly useful for tracking large-scale weather systems and providing data for flight path planning over remote areas like oceans. Satellite sensors that track high-altitude wind speeds can range from those capturing basic wind vector data to more complex imaging systems.
Smart Waste Bin with wireless ultrasonic fill-level sensors and other indicators such as temperature and tilt within waste container
Tag sensors and readers for tracking people, collecting environmental data, equipment tracking, and real-time alerts. RFID transmitter devices are mounted on headlamps belts or badge cards of miners to enable tracking of workers in real-time.
Underground mining has significant safety hazards due to high-stress concentrations, weak rock masses, and limited access and air quality. Different sensors are used in mine-related activities, such as geophones in exploration and blast control, piezometers in dewatering and toxic gas detectors in working frontlines.
