Robot workcell system design involves integrating one or more robots with components such as conveyors, pallets, machine tools, and fixtures. Previous work in workcell design has addressed control and operations management issues such as scheduling. There has been relatively little emphasis on overall design, interface, system integration and agility issues. This paper provides a detailed technical description of (1) a cost-effective approach to prototyping a robotic assembly workcell using off-the-shelf modules and sensors; and (2) the process of designing, building, and integrating a dual robot assembly cell using a programmable logic controller. Modules and sensors used include pneumatic devices, solenoids, Hall effect and optical sensors, relays, optical isolators, conveyor, programmable logic controller, and vision system. Ladder diagrams, vision system inspection tools, and an integration interface were developed to synchronize the sequence of operations and communication between hardware devices. A design framework for web-based control of the system is proposed. Future research directions include web-based monitoring, control, and troubleshooting.

Sequential control using ladder logic, Programmable Logic Controllers (PLCs), and operator interfaces are commonly used in the manufacturing industry today. The introduction course of programmable logic controller is a course that needs a lot of practice. We present a project-based approach to teaching it by introducing real engineering projects into the process of theory teaching. The students show more enthusiastic during learning course and their abilities of solving engineering problems are greatly enhanced.

This paper presents programmable logic controller based elevator control system. Primary focus is on using programmable logic controller to build the elevator model. To control the motion of the elevator through various levels DC geared motor is used. Push buttons are used to give signal to the elevator to come to the desired floor, traversing up and down. Moreover DC relays are used as switches, not protective devices, to drive the motor in clockwise and anticlockwise direction. Ladder logic is used for the model implementation.

<span>Signal Interpreted Petri Nets (SIPN) modeling has been proposed as an alternative to Ladder Logic Diagram (LLD) modeling for programming complex programmable logic controllers (PLCs) due to its high level of abstraction and functionalities. This paper proposes an algorithm to efficiently convert existing SIPN models to their LLD models equivalences. In order to automate and speed up the conversion process, matrix calculation approach is used. A complex SIPN model was used to show that existing conversion technique must be expanded in order to cater for a more complex SIPN models.</span>
