— A miniature robot with continuous jumping ability is presented in this paper. The robot has a dimension about 6cm × 8cm × 2cm and weighs 20 grams. To achieve continuous jumping, various mechanisms are needed including the jumping mechanism, energy store and release mechanism, self-righting mechanism, and jumping direction changing mechanism. The design(More)
— We present the design and implementation of a new jumping robot for mobile sensor network. Unlike other jumping robots, the robot is based on a simple two-mass-spring model. After we throw it on ground, it can stabilize itself and then jump once. The detailed mechanism design including the load holding and self-stabilization are presented. Jumping heights(More)
PURPOSE The Pro23His (P23H) rhodopsin (RHO) mutation underlies the most common form of human autosomal dominant retinitis pigmentosa (adRP). The objective of this investigation was to establish a transgenic miniature swine model of RP using the human P23H RHO gene. METHODS Somatic cell nuclear transfer (SCNT) was used to create transgenic miniature pigs(More)
— Mobile sensors with jumping ability provide several advantages compared with the traditional wheeled sensors such as ability to move in rugged terrain. A controllable jumping robot for this purpose is described in this paper. The robot has dimension about 9.5cm × 9cm × 3cm and weighs 54.1 grams. It can perform the jumping process continuously. This paper(More)
— The translational oscillation with a rotational actuator (TORA) system has been used as a benchmark for motivating the study of nonlinear control techniques. In this paper, modeling and control of a novel 2-dimensional TORA (2DTORA) are presented. The 2DTORA is an underactuated mechanical system which has one actuated rotor and two unactuated(More)

Anatomic and physiological similarities to the human make swine an excellent large animal model for human health and disease. Cloning from a modified somatic cell, which can be determined in cells prior to making the animal, is the only method available for the production of targeted modifications in swine. Since some strains of swine are similar in size to(More)
— A non-vector space control method based on compressive feedback is presented in this paper. The non-vector space means the control is not performed in traditional vector space but in the space of sets. Consider an initial set and a goal set, a stabilizing controller is designed to make the set dynamics converge to the goal set. The compressive feedback(More)
— This paper has two purposes: investigating a featureless visual servoing approach based on mutation analysis and proposing a visual servo control method for nanomanipu-lations. For the first purpose, the featureless visual servoing method is needed because traditional visual servoing relies heavily on robust feature extraction and tracking, which are very(More)
— Hopping sensors are a type of low cost mobile sensors that are small in size, have limited capability and imprecise movement. However, their unique method of movement makes them suitable for rugged terrains. Sensors may fail when deployed in a rugged terrain or in an obstacle-abundant environment. Therefore, redundant sensors may be identified and(More)
