In a Flexible manufacturing system, the Automated Guided Vehicles $$(AGV)$$ move at a speed of $$50$$ $$m/min,$$ cover an average distance of $$150$$ $$m$$ to deliver and $$100$$ $$m$$ for return. If the time required for pick-up and drop is $$30$$ $$s$$ each, neglecting idle times, then the number of $$AGV$$$$s$$ required to meet the demand of $$50$$ delivers per hour is ____________.

Each axis of $$NC$$ machine is driven by a stepper motor drive with a lead screw. The pitch of lead screw is $$p$$ $$mm.$$ The step angle of stepper motor per pulse input is $$\alpha $$ degrees/pulse. The ratio of gear drive in stepper motor drive is $$g$$(number of turns of the motor for each single turn of the lead screw). The number of pulses required to achieve a linear movement of $$x$$ $$mm$$ is
