Designers of distributed embedded systems face many challenges in determining the appropriate tradeoffs to make when defining a system architecture or retargeting an existing desi...
The bow leg hopper is a new design for a locomoting system with a resilient, flexible leg. It features a passive stance phase and natural pitch stability. It is controlled with ac...
This paper addresses the problem of reducing the hysteresis found in the actuation of most smart materials. They are divided in two groups: systems with no saturation (e.g. piezoe...
This paper addresses some performance limits of the kneed and non-kneed passive-dynamic walking machines discovered by McGeer [10, 11]. Energetic inefficiency is measured by the s...
Systems requirements errors are numerous, persistent, and expensive. To detect such errors, and focus on critical ones during the development of a requirements document, we have d...
