In this paper, the forward and inverse kinematics equations for demolition fire vehicle with 6-DOF were developed. This was done through the development of an interface that allows co-simulation using MATHEMATICA and ADAMS. The implementation of this project was done entirely in MATHEMATICA by calculating the kinematics equations to demonstrate the usefulness of this product. The forward and inverse kinematics of the demolition fire vehicle represents the position and orientation of the end-effector as any desired location. This research was particularly conducted using the simulator, and it showed good approximation results in terms of solving a reaching task problem.

In this paper, a commercial multibody dynamics program ADAMS was utilized to investigate the model for the multi-joint boom conflicts. In this process, CATIA, ANSYS and ADAMS were used to develop the simulation. The addition of ADAMS made the system more accurate and improved precision of the system. In brief, the 3D CAD model of the structure was initially developed via CATIA. After this, the CATIA models were exported to ANSYS for creating flexible-body modeling by using formatted file. Subsequently, with ADAMS, the flexible body model was directly imported from ANSYS which performed the analyses of the dynamic collision of the nozzle boom conflicts. This contained the information regarding geometry and model shapes of the flexible body. Using ADAMS/Durability, it was possible to determine the strain energy for the nozzle configuration by crashing the contact structure that was created. Via this procedure, the acquired simulation analysis of nozzle showed interestingly good results with respect to the objectives of the study

This paper aims to develop a crutched walking frame with one-wheel driving system for the walking-impaired person as the aged. The walking frame is made up of four main parts : the steering and suspension system, the driving unit using the worm gear, the sensor and the controller. The walking frame can be controlled to keep the stable attitude by using the tilt sensor that measure the tilting of frame. The experimental results without control motion and with control motion for the downhill and uphill are presented in this study. Finally, a comparison between these results is presented to show the validity of system.

In this paper, our aim is to develop a simulation model for Multi-joint demolition water vehicle. 3D model of vehicle is developed with CATIA. The rigid simulation model is built in ADAMS and the flexible simulation models are developed using ADAMS and ANSYS. The combination of the both ADAMS and ANSYS can improve the precision of system simulation. The rigid model with rigid multi-slide booms and rigid refracting booms, the hybrid model with flexible multi-slide booms and rigid refracting booms, and a flexible model with flexible multi-slide booms and flexible refracting booms are considered. The simulation analysis shows a good performance, and valuable results we are interested in are obtained.
