| Abstract: | This thesis presents the development of an Internet Hand in Hand System. A multi-channel sensor wristlet with robustness, making use of surface Electromyography (sEMG) is designed to extract biological signals of an internet user via temporal -spectral methods called Short-Time Fourier Transform (STTT) and Short-Time Thompson Transform (STIT), features of hand movement signals are transformed by an embedded blue-tooth data acquisition system. This system is combined with 2.4G wireless-networking or blue-tooth module communication technicalness and data acquisition technicalness, based on LPC2132 and wireless chip called CC2500 is designed to reduce cable connection. The major difference with other data collector is that it has achieved the wireless data transmission after the A/D conversion. It's also simple in circuit, stronge in integration anti-interference, mobility and practicality, and can be widely used in the complex environment of the industrial field. The processed signals are transmitted through internet to a wireless -driven robot hand which is controlled by Micro Controller Unit (MCU) and servo motors. It imitates the hand movements of the message sender. In this way, hand movements with different velocities and forces of an internet user can be sent and felt by others. |
