c) An industrial robot performs a machine loading and unloading operation. A PLC is used as the cell controller. The cell operates as follows: i. a human worker places a part into a nest, ii. the robot reaches over and picks up the part and places it into an induction heating coil, iii. a time of 10 sec is allowed for the heating operation, and iv. the robot reaches into the coil, retrieves the part, and places it on an outgoing conveyor. A limit switch X1 (normally open) is used to indicate that the part is in the nest in step (i). This energizes output contact Y1 to signal the robot to execute step (ii) of the work cycle (this is an output contact for the PLC, but an input interlock signal for the robot controller). A photocell X2 is used to indicate that the part has been placed into the induction heating coil C1. Timer T1 is used to provide the 10-sec heating cycle in step (iii), at the end of which, output contact Y2 is used to signal the robot to execute step (iv). Construct the ladder logic diagram for the system.

Stepper motors are used to drive the two axes of a component placement machine used for electronic assembly. A printed circuit board is mounted on the table. It must be positioned accurately for the reliable insertion of components into the board. Range of each axis = 600 mm. The lead screw used to drive each of the two axes has a pitch of 0.4 cm. The inherent mechanical errors in table positioning can be characterized by a Normal distribution with a standard deviation = 0.00045 cm. If the required accuracy for the table is 0.032 mm, determine the number of step angles that the stepper motor must have.

There is the connection scheme of a residual current device (RCD). The principle of operation: Under normal conditions, the current from L to N flows through the coils of RCD. The net magnetic flux in the circular core is zero, which results no current in the sensing coil. If any fault bypasses the coils, then the net magnetic flux is nonzero and a current is induced in the sensing coil. This makes the relay opens the switch. Let the source be 220V and the current through the load be 1 A. At some time, the test button becomes on and a current of 25 mA flows through the test button. i) Find the resistance through the test button and the load. ii) Does RCD opens the circuit if it operates for a differential current lager than 30 mA? Note: Assume that the coils on the circular core has zero resistance
