Project Summary
This is a humanoid robotic hand and it copies the hand gesture. In this project we have sensor glove which checks our hand positions and it has wireless control. It has linear degree of freedom. Arduino UNO are used as microcontroller. It is a close loop control system.
Project Objectives
To improve the human machine interface using close loop control system in order to provide safety to human performing hazardous job.
Project Implementation Method
This project based on the hand movement control robot using input transducer( Flex sensor) which sense the motion of human hand. Flex sensor is the input transducer whose resistance change with bending of fingers and a voltage signal generate which is read by master arduino. Master arduino will map the finger angels as per the input signal by the flex sensor and encode them to transmit them through the transmitter module. The signal receive at the receiver module is given to the slave arduino which will decode the received angle and then write to the servo motors. The servo motors changes the angles of robotic hand fingers according to the position of human fingers like if our fingers is at zero degree then the fingers of robotic hand is also at zero degree. The feedback transducer are attached with the robotic hand these transducer generate a feedback signal. The feedback signal is given to the slave arduino, which then map it into the robotic hand angles. The slave arduino compares both the hand and robot angles and calculate the errors and corrects the servo angles.
Benefits of the Project
It is a close loop system and it is more accurate as compare to the open loop system.
It is wireless system and it is long range.
It is light and durable.
The system can be trained with the hand of any user.
