A platform must effectively support multiple product variants over a prolonged period of time. This makes platform concept evaluation a more challenging task than a single product concept evaluation. Existing platform methods develop specific criteria in depth, yet an evaluation of alternative platforms should be based on a broad set of criteria. Based on(More)
In this paper, a miniature nonholonomic spherical rolling robot capable of navigating over two dimensional surfaces is described. This 55 gram spherical robot consists of a 6 cm diameter external spherical shell driven by an internal two-wheeled differential drive cart. A gravity powered pendulum effect is produced as the internal device climbs up the(More)
The adoption of smart grid systems has been accelerating around the world, with many pilot projects initiated throughout the developed world. However, there has been a lack of studies quantifying appliance level economic benefits that are available to the end consumers. Through coupling historical market information with an agent based residential load(More)
In recent years, concurrent engineering methods have been shown to reduce product development time and cost. The simultaneous design of product and process can also lead to improvements in product quality. There are essentially three ways to improve the quality of a product: through changes in the design, through changes in the process, or through changes(More)
This paper is concerned with pose (position and orientation) estimation of robotic end-effectors under low speed motion where its acceleration is far less than the gravity. An Extended Kalman Filter (EKF) is designed to fuse measurements from an inertial measurement unit (IMU) and a SE(3) measurement system. The IMU consists of a tri-axis accelerometer and(More)
Many natural systems have inspired the design of engineering artifacts. Example systems include a broad array of products inspired by pseudo-fractal structures found in nature, including bronchial tubes, watersheds, lightning, and leaf veins. Notably, these systems all resolve a volume-to-point flow problem, i.e., diffusive transportation of heat, energy or(More)
