Abstract:
This paper describes a brain controlled robotic leg
which is designed to perform the normal operations of a human leg. After implanting
this leg in a human, the leg can be controlled with the help of user’s brain
signals alone. This leg behaves similar to a normal human leg and it can
perform operation like walking, running, climbing stairs etc. The
entire system is controlled with the help of advanced microcontrollers and
digital signal processors. The signals are taken out from the human brain with
the help of electroencephalography technique. The person can perform operations
like walking, running etc just by their thought. This system will be very much
suitable for those who lost their legs in accidents and the proposed system is
hundred percent feasible in the real time environment with the currently available
technology.
The Brain Controlled Artificial Legs are very much
cost effective when compared to the normal Artificial legs which is available
in the market. The reduction in cost of the proposed system is found to be
above 80% when compared to the existing system. Moreover, the user can have full
control over the artificial legs which is not possible in the existing system.
