Such a solution can help soldiers stay away from unnecessary exposure to dangers yet performing the given tasks, medical supervision available to countless patients via remote assistance, and radioactive material handled by non-human counterparts where needed. At present, systems employing movement replication are limited to surgical purposes. The DaVinci system by Intuitive Surgical USA and ZEUS Robotic Surgical System by Computer Motion are two such examples. However, these systems are very costly and cannot be used for other purposes due to their large size and weight. The principle goal of the project is to provide a general purpose product which can be used in multiple situations, not just for medical purposes. The project uses a potentiometer based exo-skeleton that translates the movements of a human arm into potential differences. These potential differences are digitized using a PIC based ADC and then sent to a computer via USB. This digital sequence is transmitted to the remote system using internet, which when received, is transformed into corresponding PWM signals. These PWM signals are fed to the corresponding servos of the robotic arm to perform the movement.

The aim of this project is to provide high level speech security by scrambling in digital domain and transmitting the signal in analog domain for narrowband wireless communication. Most of the traditional scramblers require frame synchronization. This complicates the implementation and also makes transmission sensitive to the channel conditions. Digital encryption provides very high security however it is usually unsuitable for wireless applications particularly due its fundamental requirement of much wider bandwidth along with stringent synchronization both at frame and bit level. On the other hand analog scrambling technique provides relatively lower security but bandwidth is preserved.
