This paper focuses on how to improve the operation ability of a soft robotic hand (SRH). A trigger-based dexterous operation (TDO) strategy with multimodal sensors is proposed to perform autonomous choice operations. The multimodal sensors include optical-based fiber curvature sensor (OFCS), gas pressure sensor (GPS), capacitive pressure contact sensor (CPCS), and resistance pressure contact sensor (RPCS). The OFCS embedded in the soft finger and the GPS series connected in the gas channel are used to detect the curvature of the finger. The CPCS attached on the fingertip and the RPCS attached on the palm are employed to detect the touch force. The framework of TDO is divided into sensor detection and action operation. Hardware layer, information acquisition layer, and decision layer form the sensor detection module; action selection layer, actuator drive layer, and hardware layer constitute the action operation module. An autonomous choice decision unit is used to connect the sensor detecting module and action operation module. The experiment results reveal that the TDO algorithm is effective and feasible, and the actions of grasping plastic framework, pinching roller ball pen and screwdriver, and handshake are executed exactly.

Choice Decision

We introduce real decisions (a project choice decision, an investment scale decision, and an information acquisition decision) to the Dye (1985) voluntary disclosure framework and examine how the prospect of voluntary disclosure affects managers' real decisions. Riskier projects lead to more volatile environment and hence entail higher efficiency loss at the subsequent investment scale decision stage if managers are uninformed. If managers are informed, they can withhold bad information, and the value of this option is higher for riskier projects. We show that the voluntary nature of managers' disclosure may lead to two types of inefficiencies: (1) managers may choose riskier projects, which generate lower expected cash flow due to the higher efficiency loss at the subsequent decision stage, and (2) managers may overinvest in information acquisition, because informed managers with bad information have the option to pool with uninformed mangers and benefit from being overpriced.

The Cost

An optional stopping experiment was performed in which the subject had to decide not only how much information to gather prior to making a two-choice decision, but also which of three information sources to consult. The cost of consulting these sources was varied systematically, with each source having a known, fixed diagnosticity. Two loss structures were used: (1) penalty for miss = penalty for false alarm, and (2) penalty for miss = 3 × penalty for false alarm. Results indicated subjects bought too little information relative to an optimal Bayesian model. The subjects indicated a reluctance to expend the resources required to obtain the best information available. Although subjects responded to the loss variables in the appropriate direction, they did not respond with sufficient magnitude to be mathematically optimal. Future research areas are suggested.

This paper describes a meteorological detection system integrating a variety of micro-sensors. Carried by shrapnel, this system is adaptable to complex environment and can gather long-range meteorological information of the region concerned. Basic work process is as follow, the information acquisition module is delivered by shrapnel to the designated area. In the process of falling, meteorology, location and time data is obtained through the micro-sensors and GPS receiver. After analyzing and calculating by the Micro Control Unit, the information received will be transmitted to the user terminal by wireless transmission module. Thus the information collection is completed. The use of micro-sensor makes this system compact, stable and less energy consumption, so the system is worth high practical value.
