The Folding Roboscooter, Structural Analysis for an Electric Scooter Used in Urban Conditions

Creator: Arthur J. Petron | 2008

The Roboscooter is an electric, folding scooter designed for use in dense urban areas where congestion and pollution is a problem.

About this book
The Roboscooter is an electric, folding scooter designed for use in dense urban areas where congestion and pollution is a problem. Already heavily used in most European cities, scooters provide cheaper, faster transportation than cars, but parking can still be difficult. By allowing the scooter to fold - reducing its footprint by more than half- and by implementing a one-way user share model that does not require scooter ownership, many of the current issues involving transportation in dense urban areas can be addressed. As an electric vehicle, the Roboscooter's range is limited by the amount of energy it uses during travel and the current technological limitations on battery energy density. Analysis of the elements of the scooter that experience the most stress can give insights on ways to redesign key structural elements in order to make them lighter while maintaining the strength necessary for long life in a consumer environment. The structural elements that make up the main body of the scooter are subject to cyclic fatigue due to riding conditions such as bumps, which aside from decreasing the life of structural elements, also cause the largest forces on the scooter's frame. The Roboscooter was analyzed under maximum load conditions to determine the safety factor of two of the frame components that experience the most stress: the front fork and the main folding pivot axle. Both elements were found to have a safety factor of two in their current design configurations, implying that design changes will be needed to reduce the overall weight.

Reinventing the Automobile, Personal Urban Mobility for the 21st Century

Creator: William J. Mitchell, Chris E. Borroni-Bird, Lawrence D. Burns | Technology & Engineering - 2010-01-29

This book provides a long-overdue vision for a new automobile era.

Publisher: MIT Press

About this book
This book provides a long-overdue vision for a new automobile era. The cars we drive today follow the same underlying design principles as the Model Ts of a hundred years ago and the tail-finned sedans of fifty years ago. In the twenty-first century, cars are still made for twentieth-century purposes. They are inefficient for providing personal mobility within cities -- where most of the world's people now live. In this pathbreaking book, William Mitchell and two industry experts reimagine the automobile, describing vehicles of the near future that are green, smart, connected, and fun to drive. They roll out four big ideas that will make this both feasible and timely.The fundamental reinvention of the automobile won't be easy, but it is an urgent necessity -- to make urban mobility more convenient and sustainable, to make cities more livable, and to help bring the automobile industry out of crisis.

About this book
If you've ever read a book on an e-reader, unleashed your inner rock star playing Guitar Hero, built a robot with LEGO Mindstorms, or ridden in a vehicle with child-safe air bags, then you've experienced first hand just a few of the astounding innovations that have come out of the Media Lab over the past 25 years. But that's old hat for today's researchers, who are creating technologies that will have a much deeper impact on the quality of people's lives over the next quarter century. In this exhilarating tour of the Media Lab's inner sanctums, we'll meet the professors and their students - the Sorcerers and their Apprentices - and witness first hand the creative magic behind inventions such as: * Nexi, a mobile humanoid robot with such sophisticated social skills she can serve as a helpful and understanding companion for the sick and elderly. * CityCar, a foldable, stackable, electric vehicle of the future that will redefine personal transportation in cities and revolutionize urban life. * Sixth Sense, a compact wearable device that transforms any surface – wall, tabletop or even your hand - into a touch screen computer.* PowerFoot, a lifelike robotic prosthesis that enables amputees to walk as naturally as if it were a real biological limb. Through inspiring stories of people who are using Media Lab innovations to confront personal challenges - like a man with cerebral palsy who is unable to hum a tune or pick up an instrument yet is using an ingenious music composition system to unleash his “inner Mozart”, and a woman with a rare life-threatening condition who co-invented a revolutionary web service that enables patients to participate in the search for their own cures - we'll see how the Media Lab is empowering us all with the tools to take control of our health, wealth, and happiness. Along the way, Moss reveals the highly unorthodox approach to creativity and invention that makes all this possible, explaining how the Media Lab cultivates an open and boundary-less environment where researchers from a broad array of disciplines – from musicians to neuroscientists to visual artists to computer engineers - have the freedom to follow their passions and take bold risks unthinkable elsewhere. The Sorcerers and Their Apprentices can serve as a blueprint for how to fix our broken innovation ecosystem and bring about the kind of radical change required to meet the challenges of the 21st century. It is a must-read for anyone striving to be more innovative as an individual, as a businessperson, or as a member of society. Also includes 16 pages of color photos highlighting some of the lab's most visually stunning inventions - and the people who make them possible.
