Human machine interaction systems encounters convergence

Human machine interaction systems are those of much needed in the emerging technology to make the user aware of what is happening around. It is huge domain in which the smart material enables the factor of convergence. One such is the piezoelectric crystals, is a class of smart material and this has an incredible property of self-sensing actuation (SSA). This property of SSA has added an indescribable advantage to the robotic field by having the advantages of exhibiting both the functionality of sensing and actuating characteristics with reduced devices, space and power. This paper focuses on integrating the SSA to drive an unmanned ground vehicle with wireless radio control system which will be of great use in all the automation field. The piezo electric plate will be used as an input device to send the signal to move the UGV in certain direction and then, the same piezo-electric plate will be used as an actuator for haptic feedback with the help of drive circuit if obstacles or danger is experienced by UGV.

Design and Development of Robots End Effector Test Rig

A Test Rig for end-effectors of a robot is designed such that it achieves a prismatic motion in x-y-z axes for grasping an object. It is a structure, designed with a compact combination of sensors and actuators. Sensors are used for detecting presence, position and disturbance of target work piece or any object and actuators with motor driving system meant for controlling and moving the mechanism of the system. Hence, it improves the ergonomics and accuracy of an operation with enhanced repeatability.
