During the final a long time, the expansion of micro-electronics has diminished the price of computing energy to a degree appropriate to and has made attainable refined keep an eye on recommendations compatible for lots of purposes. Vibration c- trol is utilized to every kind of engineering structures to acquire the specified dynamic habit, more advantageous accuracy and elevated reliability in the course of operation. during this context, you can think about purposes relating to the keep an eye on of constructions’ vib- tion isolation, regulate of auto dynamics, noise regulate, keep an eye on of machines and mechanisms and keep an eye on of ?uid-structure-interaction. you will proceed with this record for a very long time. examine within the ?eld of vibration regulate is very accomplished. Pr- lems which are average for vibration keep an eye on of nonlinear mechanisms and str- tures come up within the ?elds of modeling platforms in the sort of manner that the version is appropriate for keep watch over layout, to settle on acceptable actuator and sensor destinations and to choose the actuators and sensors. Theobjective of the Symposium used to be to offer anddiscuss methodsthat give a contribution to thesolution of such difficulties and to illustrate the cutting-edge inthe ?eld proven by way of standard examples. The goal was once to guage the boundaries of functionality that could beachievedby controlling the dynamics, and to indicate gaps in current learn and provides hyperlinks for components offuture research.Mainly, it introduced jointly major specialists from relatively assorted parts featuring theirpoints of view.

Key words: humanitarian demining, mine action, master-slave bilateral control hand system, mine hunter vehicle. 1. INTRODUCTION Since 1999, our group has been involved in the research and development [1] of landmine detection and clearance technology with the aim of maximizing safety and increasing the overall speed in humanitarian demining as shown in Figure 1. Currently Chiba University’s group is participating in the Japan Science and Technology Agency’s (JST) Sensing and Access Control R&D for Humanitarian Mine Action project [2] with our effort to develop a small vehicle named Mine Hunter Vehicle with two arms, one is the SCARA arm having mine detection sensor, the other one is the multiple link arm for mine clearance as shown in Figure 2.

In practice the positions of obstacles and mines will always be different, so arm positioning cannot be solved offline in advance. Therefore this system will always use reference generation with online inverse kinematics to solve the positioning problem. 9 between the current position and the reference position. The trajectory is calculated according to Eq. (1) y= 2π xp − xn xp + xn cos (t − tn ) + . 2 T 2 (1) Here, xp is the initial reference position, xn is the next reference position, T is the period in seconds, and tn is the predefined time at which xn is achieved.
