This paper examines various theories of innovation and sees how they apply to a system of systems framework. Systems of systems present an unusual challenge for innovation theory because some of the basic rules of the theory are broken by the system of systems paradigm. In particular, systems of systems are often deployed to solve complex problems that have a pressing need. However, pressing problems...
The search for signs of past or present life on planetary surfaces such as Mars is a high priority objective of international space agencies. At present and in the near future, the most promising means to conduct such searches employ robotic systems that operate from planetary orbits or on planetary surfaces. This paper presents a robotic system concept for mobile search and surveying on planetary...
This paper proposes a quantitative method to describe how complex an environment looks to an individual robot. The assumption is that robots are designed to perform a task in a specific setting or group of settings. The structure of the environment and knowledge the robot has about the environment determine how sophisticated the robot hardware and control algorithms need to be to perform a given task...
The field of robotics is on a growth curve, with most of the growth expected in the areas of personal and service robots. As robots become more prevalent in chaotic home and industrial settings, they will be required to make increasingly independent decisions about how to accomplish their tasks. A key to accomplishing this is the development of techniques to allow robots to handle severe uncertainty...
Several oscillator-based robot controllers were tested for effectiveness in exploring a dynamic environment. The goal of the project was to have a team of three robots explore an arena with variable lighting and obstacle patterns and, as a team, absorb as much light as possible. Reinforcement learning was used to optimize the parameters of a coupled nonlinear oscillator controller for operation in...
Self-heated thermistor techniques to measure perfusion suffer from the lack of a widely accepted perfusion model. It has been previously proposed that perfusion be modeled as an effective thermal conductivity. It has also been proposed that effective and intrinsic tissue conductivities can be simultaneously measured using sinusoidal heating of thermistors embedded in tissue. A microcomputer-based...
