EXPERIMENTAL SET-UP FOR THE MEASUREMENT OF THE PERCEIVED INTENSITY OF VIBRATIONS

A new experimental set up for the measurement of the perceived intensity of vibrations transmitted to a finger is presented. The related measurement procedure includes two independent tests for a jury of subjects, whose results are jointly processed to attain the corresponding scale. The requirements and the features of experimental set up realized for producing and controlling the vibration stimuli are discussed in detail. The user interfaces implemented for gather the perception responses of the subjects are also discussed and illustrated.

PROBABILISTIC INTENTION CLASSIFICATION FOR HUMAN AUGMENTED COGNITION SYSTEM

In this paper, we present a probabilistic human implicit intention classification using user’s eye gaze data for human augmented cognition system. The Ultimate purpose of this method is to implement a human augmented cognition system which can provide a specific service to address the cognitive limitations of human brain. In order to partially overcome the cognitive limitations, the system should be able to control the flow of information. Therefore, a specific intention classification using a Naïve Bayes classifier can be used as useful tool for searching and retrieving specific information according to the human intention and situation.

COMPARATIVE STUDY ON KINEMATIC CHARACTERISTICS OF THREE MICRO-SURGICAL MECHANISMS FOR NEUROSURGICAL OPERATIONS

Most of commercialized micro surgical robot modules are built based on the typical 6-UPS Gough-Stewart Platform (GSP) structure. However, they may be overqualified in neurosurgical operations in aspects of workspace size, the number of motion Degree-Of-Freedoms (DOFs), and their costs. Thus, this paper suggests two different parallel mechanisms (PMs), which are a 3-UPS + PPPS type PM and a 2-UPS + PPPU type PM, as candidates for micro neurosurgical robot modules. Through a comparative study of two suggested PMs and the GSP PM in aspects of various factors such as kinematic isotropy characteristics, the workspace size required in neurosurgical operations, commercial linear actuator stroke limitations, etc., it is shown that the 2-UPS+PPPU type PMs is superior to the other two structures.

ROBOT FINGERTIP MODULE FOR MEASURING CONTACT FORCE AND LOCATION

This paper presents an exchangeable and inexpensive robot fingertip module for tactile sensing for the control of the robot hands. The developed module has real human fingertip scale and shape, and can detect contact force and location simultaneously. It has a thin-film type force sensor constructed with 37 unit cells as array, and it also includes a simple on-board chip for signal processing. The sensors are fabricated by using a simple screen printing technique. The whole fabrication process of the module including sensor and signal processing parts are suitable for mass production because of its very simple and low-cost process.

IMPEDANCE SENSING MECHANISM FOR A NEW MINIATURE HAPTIC ACTUATOR BASED ON MR FLUIDS

Previously, we successfully developed a new miniature haptic actuator based on MR fluids, designed to convey realistic and various kinaesthetic sensations to users in small electronic devices. The haptic sensation, which is generated in the form of resistive force, should vary accord-ing to user’s press for demonstrating its real-world haptic application. Thus, a sensing method for gauging the pressed depth by users should be integrated into the proposed actua-tor. To determine the pressed depth of the MR actuator, this study proposes an impedance sensing mechanism for meas-uring the impedance change of the solenoid coil embedded in the actuator in the form of voltages to estimate the pressed depth. The sensing capability of the proposed sens-ing mechanism was evaluated. The results show that the sensitivity of the proposed impedance sensing method is sufficient to regulate the output resistive force over a small stroke range of the actuator.

MEASUREMENT OF WALKING GAIT FOR 3D PASSIVE DYNAMIC BIPED WALKER

Passive dynamic bipedal walking (PDW) is an attractive topic not only for robotics field but also the other scientific fields, i.e. physics and biology. In order to clarify its mechanism of walking, many researchers have developed various PDW machines. We also have developed several 3-D PDW with flat feet and ankle springs. However there are no researches on the measurement of 3-D PDW gait, which reveals its mechanism precisely. This paper, therefore, describes measurement of walking gait of 3-D PDW such as zero moment point (ZMP) and its posture which are often measured for human gait analysis. A unique flexible displacement sensor and a usual 6 axes force sensor are utilized for the measurement. As a result, ZMP trajectory draws ‘8’ shape pattern, which is similar to that of human. Moreover the measurement system clarified the relationship between walking gait and ballast position which is effective for stabilization.

SOFTWARE FOR ORIENTATION SENSOR CHR6-DM

This article describes software solutions for specific type of orientation sensor which has a factory identification CHR6-DM. On the PCB (Printed Circuit Board) of CHR6-DM are placed chips for providing accelerometer data, gyros rates data and magnetometer data. These data are used for calculation of values for determining the Yaw, Pitch and Roll values. Data from CHR6-DM are processed by the developed software and displayed in main form of software for testing orientation and EMI (ElectroMagnetic Interference). Software will also be used for project of mobile autonomic robotic system.

SET-UP FOR PRECISION ROBOTIC EVALUATION OF AC CURRENT CLAMP

Metrology often takes an important part in robotics. Reversed relation, where robotics is employed in metrology, however, is less often met. The paper investigates the use of a robot for evaluation of spatial uniformity of precision current clamp. Robot moves the clamp around the conductor, where effect of clamp windings position on a measured current can be observed at high resolution. The set-up is presented together with the measurement procedure and results, which include complete metrological evaluation of current clamp.
