ROBOTICS ON COUNTRY GROWTH
ROBOTS
MAKE OUR WORK LIGHTER, BUT
WE HAVE MADE THE ROBOTS LIGHTER.
Industrial robots, which are heavy moving bodies, show high risk of damage
when working and also during training sessions in dense environment of other robots.
This initiated the allure for lighter robot constructions using soft arms. This paper reports on the design of a biorobotic actuator. Data from several vertebrate species (rat, frog, cat, and human) are used to evaluate the performance of a McKibben pneumatic actuator. Soft arms create powerful, compact, compliance and light robotic arms and consist of pneumatic actuators like McKibben muscles. Currently there are some trajectory problems in McKibben muscles which restrict its application. This paper presents solutions to certain problems in the McKibben muscles by the use of Electro Active Polymers (EAP).The main attractive characteristic of EAP is their operational similarity to biological muscles, particularly their resilience and ability to induce large actuation strains.
Electro Active Polymers (EAP) as sensors, which simplify a robotic finger models by acting like an actuator (sensor cum actuator). Ion-exchange Polymer Metal Composite (IPMC), one of the EAPs ,has been selected by us ahead of its alternatives like shaper memory alloys and electro active ceramics and the reason for its selection is also discussed in this paper.
We devise a unique model to eliminate trajectory errors by placing EAP stripes in robots’ joints, which can also be applied to current (heavy) robots actuated by motors. This paper would obliterate all the difficulties currently present in McKibben muscles system, which currently restricts its application. Adroit use of the solutions provided in this paper would abet researchers to produce highly efficient artificial muscles system. We give the idea of an artificial muscle system which consume “less energy & oxygen” than a natural one. Therefore we discuss the world’s most energy efficient robot with our innovative idea.

ROBOTICS:
A Friend For Assisting Handicapped People.
A Friend For Assisting Handicapped People.
This article presents the Robotic system FRIEND, which was developed at the University of Bermen’s Institute of Automation(IAT). This system offers increased control functionality for the disabled users. FRIEND consists of an electric wheel-chair, equipped with the robot arm MANUS. A computer controls both the devices the man-machine interface(MMI) consists of a flat screen and a speech interface. FRIEND’s hardware and software are described first. The current state of development is then presented, as well as research results that will be integrated soon. After a short explanation of speech interface, the methods developed for semiautonomous control are described. These are programmed by demonstration, visual servoing and configuration planning based on the method of imaginary links. We also described the state of integration and our experience to date.
