This study describes the amphibious study of a novel robot, which attempts to emulate the basilisk lizard’s ability to run on the surface of water and walk on land. Functionally, the robot uses four bar mechanism as its driving leg with a self-adaptive foot added to its end. Through some hydromechanics calculations and analyses, its water running ability is theoretically verified. And via terre...

This paper outlines our work in developing telemedicine in portable rehabilitation robot monitor system with 3-D Exercise Machine for Upper Limb, coordination, range of motion and other relevant perceptual motor activities. The preliminary result of this study is the initial evaluation of a device for robotic assisted upper extremity repetitive therapy; the robot has four degrees of freedom at ...

A stBtlCBl-l-y-bBI-Bnced direct drive robot monlpul-otor with new Brchltecture Is constructed Bt the University of MlnnesotB for stBbll-lty BnBl-ysls of ImpedBnce Control[8,10,11).

The hardware and software co-design for five axes robot arm, is aimed to perform pick and place operation by controlling the speed and position, using FPGA, H-bridge driver and Sensor circuit. Digital PWM is used to control speed of DC motor. The hardware functional block designed in software module with the help of VHDL coding as FPGA technology has blurred the distinction between hardware and...

The designers of civil engineering structures often have to face the problem reliability complex computational analyses performed most with Finite Element Method (FEM). Any assessment such is difficult and can only be approximate. present paper puts forward a new method verification validation structural upon an illustrative example dome strengthened by circumferential ribs along upper lower ed...

The electric arc furnace (EAF) is one of the popular methods of steel production from steel scraps. The plasma arc is used in EAF to generate heat for melting scarp or direct reduced iron (DRI). The liquid metal is drained from the EAF through the tap hole. Nowadays, it is critical to use Automated/robotic tools for opening the tap hole with oxygen lancing. Because many workers have been blinde...
