This video presents the state estimation, control, and trajectory planning in cooperative transportation of structures, which are either too heavy or too big to be carried by small micro vehicles. We consider small quadrotors, each equipped only with a single camera and IMU as a sensor. We present a new approach to coordinated control which allows independent control of each vehicle while guaranteeing the system’s stability and a new cooperative localization scheme that allows each vehicle to benefit from measurements acquired by other vehicles. The later is formulated as an optimization problem exploiting the rigid structure information. We reach speeds of over 4.2 m/s, which angular rates close to 300 deg/s and accelerations up to 5 m/s^2.
Welcome to drone day on the Adafruit blog. Every Monday we deliver the latest news, products and more from the Unmanned Aerial Vehicles (UAV), quadcopter and drone communities. Drones can be used for video & photography (dronies), civil applications, policing, farming, firefighting, military and non-military security work, such as surveillance of pipelines. Previous posts can be found via the #drone tag and our drone / UAV categories.
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.
