The embedded software is designed and tested with the slurry filing system. Whole assembly is integrated with embedded system to automatically control its operation through PC. The driver has been tested with stepper motor with linear guide assembly for every axis separately. We have fabricated slurry filling system having three stepper motors for controlling X axis, Y axis, and Z axis (piston bottle top dispenser) movement respectively.We have also designed 2 Amp stepper motor driver having option to select half and full step pulse sequence to be applied for stepper motor.The driver can precisely drive the stepper motor with the minimum resolution of 3 µm. For ontrolling mechanical movement of dispenser, stepper motors with linear actuator having different holding torque, weight and current has been used for X, Y and Z axis. For dispenser design we have modified a manually operated bottle top dispenser such that its dispensing action can be automatically controlled from PC. All mechanical parts are integrated to make standalone semi-automatic dispensing system. Mechanical parts with linear actuator, lead screw and linear guide has been designed by us and fabricated for X, Y and Z axis stages. In view of this we have designed and developed three axis stage including X,Y and Z axis control with dispensing control mechanism. MED can be initiated by imparting sufficient electrical energy to produce plasma on the surface of MED and it in turn initiates the high sensitive primary explosive pasted on its surface. ![]() To use MEDs in field we have to put slurry of primary or secondary explosive materials on the surface of MED for making physical contact between primary explosive and MED. MEDs are used in field with extremely sensitive primary explosive material for initiating secondary explosives. Microelectric Detonators (MED) is the new and emerging field in the miniaturize electro explosive devices. ![]()
