in this paper, an innovative mobile platform is presented which is equipped by three new wheels. the core of the new idea is to establish a new design of rigid circular structure which can be implemented as a wheel by variable radius. the structure of wheel includes a circular pattern of a simple two-link mechanism assembled to obtain a wheel shape. each wheel has two degrees of freedom. the fi...

We describe in detail a novel kinematic simulation of a three-wheeled mobile robot moving on extremely uneven terrain. The purpose of this simulation is to test a new concept, called Passive Variable Camber (PVC), for reducing undesirable wheel slip. PVC adds an extra degree of freedom at each wheel/platform joint, thereby allowing the wheel to tilt laterally. This extra motion allows the vehic...

Developing adaptable and flexible product architectures provides for meaningful levels of cosmetic, electronic, ergonomic, structural, and material customization. Today, automobiles are the result of intricate supply chains, integrated manufacturing techniques and just-in-time manufacture of component modules. While these changes have compensated for increased complexity and sophistication at c...

With the increasing rise of professionalism in sport, athletes, teams, and coaches are looking to technology to monitor performance in both games and training in order to find a competitive advantage. The use of inertial sensors has been proposed as a cost effective and adaptable measurement device for monitoring wheelchair kinematics; however, the outcomes are dependent on the reliability of t...
