A great piece from Robots.net about the robot Wave Glider that survived Sandy, collecting data all along the way. (Which I found via DIY Drones.)
An autonomous Wave Glider robot named Mercury floated alone in the path of Hurricane Sandy about 100 miles east of Toms River, New Jersey. The robot survived 70 knot winds on the ocean’s surface while its sensors gathered weather data and transmitted it in real time. The robot recorded a drop in barometric pressure of more than 54 mbars with a low of 946 mbars. The robot also carries cameras, wave sensors, fish trackers, hydrophones, temperature sensors, conductivity sensors, dissolved oxygen sensors, magnetometer, GPS, and a flurometer. For more details on what this robot does, see the article Air-Sea Interface Monitoring of Hurricanes at the Liquid Robots website. For some technical details of the robot itself, see the Wave Glider Technology Brief (PDF format) and Wave Glider Specifications document (PDF format).
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
