NMP - NMP2-CT-2005 -016680 Instrument: STREP
Page 1 Adaptive Robots for Flexible Manufacturing Systems Thematic priority 3– NMP - NMP2-CT-2005 -016680 Instrument: STREP The ARFLEX Project 1. Introduction The ARFLEX project (Adaptive Robot for FLEXible manufacturing systems - IST-NMP2-016680) has been funded by the European Community in the context of the Six Programme Frame with the aim to introduce a radical innovation to the existing industrial robots by means of the most advanced technologies in control theory, embedded systems, sensor devices and vision systems. The ARFLEX Consortium is composed by seven partners, as showed in Figure 1: EICAS Automazione S.p.A (Project Coordinator, Italy), COMAU Robotics (Italy), ACTUA S.r.l (Italy), Jozef Stefan Institute (Slovenia), Institute of Mechatronic Systems (Switzerland), the University of Antwerp (Belgium) and the Fraunhofer Institut Produktionsanlagen und Konstruktionstechnik (Germany). Figure 1: ARFLEX Consortium Page 2 The challenging project objective is to overcome the mechanical limitations of the current robotic systems, due to the limited stiffness in the arms, the large imprecision in the coupling joints, and, in general, the non- linearity and friction effects, in order to improve the absolute accuracy positioning of the robot tool centre point (TCP) up to 0.1 mm and the robot flexibility by embedding advanced real-time control techniques, electronic devices, force and vision sensors. After three years of research and development, the ARFLEX Project has been successful concluded with the achievement of all the objectives in term of accuracy, flexibility, adaptability and low costs. The fulfilment of the expected results represents a further important change in the industrial robots and the relating applications with direct impact in the market of the manufacturing sectors, by extending the use of robots from high volume to lower volume products, shifting manufacturing operations to robots from other machining tools, thus reducing the portion of manual works. -

Automatic Control Design of the Amazing Ball with the EICASLAB suite Webinar n.3 Rapid Control Prototyping - Fundamentals - Rapid Control Prototyping . State of art . EICASLAB innovative approach . Rapid Control Prototyping (RCP) in EICASLAB • Scheduling, cores & threads • RCP on field • Slow Motion • SIM RCP • EICASLAB tools to support RCP Rapid Control Prototyping: state of art The Rapid Control Prototyping (RCP) is a process which lets the engineer quickly test and iterate its control strategies on a real-time computer with real input/output devices: the plant under control is real, the control strategy is downloaded and then executed in real-time in a specific and separated Real-Time Hardware Box that can be commanded through a non real- time host computer and that has limited capabilities to record data for tuning and debugging purposes. EICASLAB innovative approach time The approach is based on the idea - that by using Simulation Modelling & Modelling Like Real Like • a single IDE (the EICASLAB suite) and • a standard PC (the EICASLAB RCP Platform) + Prototyping Rapid Control Rapid it is possible to gather all the control design activities (from system concept to final code generation of code for the final target and the validation test Target + campaign).

ARM and Embedded System Code: 17EC62 Table of Contents
BMS INSTITUTE OF TECHNOLOGY AND MANAGEMENT Avalahalli, Doddaballapura Main Road, Bangalore – 560064 Electronics and Communication Engineering Subject: ARM and Embedded System Code: 17EC62 Table of Contents Sl.No Modules Page.No 1 1 1-13 2 2 14-38 3 3 39-78 4 4 79-92 5 5 93-126 EMBEDDED SYSTEM COMPONENTS MODULE-3 .DEFINITION OF AN EMBEDDED SY STEM An embedded system is a combination of 3 types of components: a. Hardware b. Software c. Mechanical Components and it is supposed to do one specific task only. Example 1: Washing Machine A washing machine from an embedded systems point of view has: a. Hardware: Buttons, Display & buzzer, electronic circuitry. b. Software: It has a chip on the circuit that holds the software which drives controls & monitors the various operations possible. c. Mechanical Components: the internals of a washing machine which actually wash the clothes control the input and output of water, the chassis itself. Example 2: Air Conditioner An Air Conditioner from an embedded systems point of view has: a. Hardware: Remote, Display & buzzer, Infrared Sensors, electronic circuitry. b. Software: It has a chip on the circuit that holds the software which drives controls & monitors the various operations possible. The software monitors the external temperature through the sensors and then releases the coolant or suppresses it. c. Mechanical Components: the internals of an air conditioner the motor, the chassis, the outlet, etc An embedded system is designed to do a specific job only. Example: a washing machine can only wash clothes, an air conditioner can control the temperature in the room in which it is placed. -

RCP OPERATIVE MODE The overall Rapid Control Prototyping (RCP) activity is managed by the EICASLAB RCP module, that provides a set of tools and advanced features devoted to RCP Highlights quickly test and iterate the control strategies on a computer equipped with a real-time operating system and with real input/output devices before transferring • All the control design phases in them in the final hardware target. only one PC equipped with Linux RTOS and EICASLAB Suite THE INNOVATIVE RAPID CONTROL PROTOTYPING APPROACH IN EICASLAB • Rapid Control Prototyping in Rapid Control Prototyping or RCP is a process which three steps: RCP on field, Slow lets the engineer quickly test and iterate the control Motion and SIM RCP strategies on a dedicated hardware equipped with a real-time operating system and with real input/output devices: the plant under control is real and the control • Powerful multi-threading and strategy is executed in real-time in a hardware that can be commanded through a host computer where multi-core programming data recording capabilities for tuning and debugging techniques purposes are required. Nowadays the RCP activity foresees the use of • Easy configuration of HW different development environments and hardware interfaces and control activities boxes in order to perform the RCP process. This method forces the developers to export and to import real-time scheduling continuously and iteratively software modules among the different environments with the risk to introduce • Control system testing on the real bugs at each import/export of the source code. These conversions are often uncomfortable and the RCP plant and emulation of final HW process performance (cost, effort, effectiveness, etc.) architecture with only one PC can be improved by gathering all the phases into a unique development environment (HW/SW) as proposed by the innovative Rapid Control Prototyping approach introduced in EICASLAB.
