BMI Systems for Controlling Robotic Arm


A brain machine interface has been developed by the researchers in order to manipulate a robotic arm when the subject’s hands are engaged in the different activities. This new system of the researchers has been published in many news papers in which it is reported that they are efficient in working in testing with volunteers.

There are multiple previous researches by students of Jaipur EngineeringColleges with the help of which researchers developed of BMI systems. In such kinds of systems, a user wears a cap with electrodes and performs an activity such as moving a ball on the table and then this system records the brain wave activity which takes place as soon as the person moves the ball.

In the next demonstration of the researchers, the person have been asked simply to think about the performing various activities so that system could monitor their brain waves and compare them to the earlier stored pattern which was recorded while performing the task.

When the same brain wave pattern is detected by the system, a robotic arm was engaged which is preprogrammed for mimicking the actions of the human activity. This system has been programmed by the researchers in order to reproduce a human activity by suing human thoughts.

As there were multiple prior efforts by the researchers and Top MBA College in Jaipur with BMI systems but they have only focused only on instigating the activity. But in this new study, they have efficiency of a BMI system by considering targeted robotic action while the person is engaged in the other activity.

Their result is the system through which a person can control three limbs at once. In order to test and demonstrate this system, volunteers have been asked to participate in BMI training and using this system for balancing a ball on the flat surface along with use of robotic arm for grabbing and moving an empty bottle. 

It is reported by the researchers that these volunteers have fallen into two different groups which are those who were quite successful to carry out desired tasks and those who were not.

Face Recognition by Brains

A new computational model has been developed by the team of researchers that deals with face recognition mechanism of the human brain and it seems to capture aspects of the human neurology which has been missed by the previous models. A machine learning system has been developed by the team of researchers which implemented their model as well as trained it in order to recognize particular faces by feeding it a battery of the sample images.  It has been found by the researchers with Best Engineering College Jaipur that this trained system also included an intermediate processing step which represented a face’s degree of rotation but not the direction which is left or right. This property has not been built in this system as it has emerged spontaneously from the training process but on the same hand, it duplicates an experimentally observed feature of the primate face processing mechanism.  This has been considered as an indication by the researchers that their system as w...

Significance of Benchmarking in Organization

We can take the meaning of bench marking by the process of establishing the level of excellence as well as comparing our activities and actions of business or products or services or an enterprise as a whole along with those all standards that could be used increasingly by healthcare institutions in order to reduce the expenses as well as at the same time, in improving product and serve quality.  According to the team of researchers with Top Private Engineering College in Jaipur , the process of bench marking is the continues process as a component of total quality management by which an organization is able to measure as well as compare its own processing with those organizations which are leaders in the specific area. The process of benchmarking should be considered as a part of quality management programs not as any kind of replacement.  There are mainly for kinds of benchmarking which are internal competitive, functional as well as generic. With the help of internal ...

Biology Kit for Students

Educational kits have been designed by the team of researchers that can be used in order to perform experiments with the DNA for the purpose of producing glowing proteins, scents and other observed phenomena. This kit has been designed by the researchers in order to help the students in gaining a better grasp of the biological concepts. This can be used by the biological teachers and Private M Tech Colleges in Jaipur also in order to demonstrate the essential concepts such as translation of DNA into the proteins or students could learn from it a lot such as designing their own synthetic biology circuits. The main goal of the researchers behind this innovation is to serve as a creative outlet for the young individuals as well as show them the importance of biology platform. As per the researchers, by creating these educational kits that could be utilized in classrooms or in the home, they could introduce them to the young people and adults who want to make their career in bi...
