Book Description
This text is a thorough treatment of the rapidly growing area of aerial manipulation. It details all the design steps required for the modeling and control of unmanned aerial vehicles (UAV) equipped with robotic manipulators. Starting with the physical basics of rigid-body kinematics, the book gives an in-depth presentation of local and global coordinates, together with the representation of orientation and motion in fixed- and moving-coordinate systems. Coverage of the kinematics and dynamics of unmanned aerial vehicles is developed in a succession of popular UAV configurations for multirotor systems. Such an arrangement, supported by frequent examples and end-of-chapter exercises, leads the reader from simple to more complex UAV configurations. Propulsion-system aerodynamics, essential in UAV design, is analyzed through blade-element and momentum theories, analysis which is followed by a description of drag and ground-aerodynamic effects. The central part of the book is dedicated to aerial-manipulator kinematics, dynamics, and control. Based on foundations laid in the opening chapters, this portion of the book is a structured presentation of Newton–Euler dynamic modeling that results in forward and backward equations in both fixed- and moving-coordinate systems. The Lagrange–Euler approach is applied to expand the model further, providing formalisms to model the variable moment of inertia later used to analyze the dynamics of aerial manipulators in contact with the environment. Using knowledge from sensor data, insights are presented into the ways in which linear, robust, and adaptive control techniques can be applied in aerial manipulation so as to tackle the real-world problems faced by scholars and engineers in the design and implementation of aerial robotics systems. The book is completed by path and trajectory planning with vision-based examples for tracking and manipulation.

Book Description
The New York Times–bestselling author of H is for Hawk explores the human relationship to the natural world in this “dazzling” essay collection (Wall Street Journal). In Vesper Flights, Helen Macdonald brings together a collection of her best loved essays, along with new pieces on topics ranging from nostalgia for a vanishing countryside to the tribulations of farming ostriches to her own private vespers while trying to fall asleep. Meditating on notions of captivity and freedom, immigration and flight, Helen invites us into her most intimate experiences: observing the massive migration of songbirds from the top of the Empire State Building, watching tens of thousands of cranes in Hungary, seeking the last golden orioles in Suffolk’s poplar forests. She writes with heart-tugging clarity about wild boar, swifts, mushroom hunting, migraines, the strangeness of birds’ nests, and the unexpected guidance and comfort we find when watching wildlife.

Book Description
Filled with heart, humor, and relevance, this side-splitting picture book, Two Many Birds, by author/illustrator Cindy Derby, opens minds and entertains all at once. As birds line up to perch on a tree, a monitor shouts rules at them: No fluffin' feathers! No pooping on the ground! No nudity! Eventually, the tree fills to capactiy (100 birds), but what happens when two more are accidentally born among the branches?

Book Description
They follow flight paths and habitats of birds, from the Victorian Mallee to the forests of South East Asia, to Japan and the South of France. Sometimes, as the painter says, its almost as if I am looking at the earth with a birds eye view the birds suggest new ways of telling stories about the earth.

Book Description
In Bird Brother, Rodney Stotts shares his unlikely journey to becoming a conservationist and one of America's few Black master falconers. Rodney grew up in Washington, D.C. during the crack epidemic, with guns, drugs, and the threat of incarceration affecting the lives of everyone he knew. He was no exception, but he was also employed by the newly founded Earth Conservation Corps, helping to restore and conserve the polluted Anacostia River. This work eventually sent his life in a different direction, as he began to train to become a master falconer and to develop his own raptor education program and sanctuary. Eye-opening, witty, and moving, Bird Brother is a testament to the healing power of nature, and a reminder that no matter how much heartbreak we've endured, we still have the capacity to give back to our communities and follow our dreams.

Book Description
Writer Susan Tweit and her economist-turned-sculptor husband Richard Cabe had just settled into their version of a “good life” when Richard saw thousands of birds one day—harbingers of the brain cancer that would kill him two years later. This compelling and intimate memoir chronicles their journey into the end of his life, framed by their final trip together, a 4,000-mile-long delayed honeymoon road trip. As Susan and Richard navigate the unfamiliar territory of brain cancer treatment and learn a whole new vocabulary—craniotomies, adjuvant chemotherapy, and brain geography—they also develop new routines for a mindful existence, relying on each other and their connection to nature, including the real birds Richard enjoys watching. Their determination to walk hand in hand, with open hearts, results in profound and difficult adjustments in their roles. Bless the Birds is not a sad story. It is both prayer and love song, a guide to how to thrive in a world where all we hold dear seems to be eroding, whether simple civility and respect, our health and safety, or the Earth itself. It’s an exploration of living with love in a time of dying—whether personal or global—with humor, unflinching courage, and grace. And it is an invitation to choose to live in light of what we love, rather than what we fear.
