PROJECT DESCRIPTION

FlexRay is the latest communication system that will support the needs of future in-car control applications. At the core of the FlexRay system is the FlexRay communications protocol. The protocol provides flexibility and determinism by combining a scalable static and dynamic message transmission, incorporating the advantages of familiar synchronous and asynchronous protocols.

The FlexRay system is targeted to support data rates of up to 10Mbit/sec with increased flexibility for easy system extension and the dynamic use of bandwidth. The 10Mbit/sec data rate is available on two channels, giving a gross data rate of up to 20Mbit/sec. http://www.flexray.com/

The purpose of the FlexRay Conformance Test Execution Project was to program and then test the conformance of devices (embedded, stand-alone nd FPGA) with the FlexRay protocol specification.

PROJECT ACTIVITY

System programming (in C), analysis and mapping of the controller host interface (CHI) and implementation of the embedded/stand alone or FPGA device for FlexRay conformance tests.http://www.ift.rwtuev.de/sections/eit_flexray.htm

The project involved system programming for the embedded board such as for the Philips µProcessor SJA2510 as also for Freescale, Bosch and NEC (E-Ray IP). Partial work was carried out at the Fraunhofer IMS, Duisburg. http://www.ims.fraunhofer.de

PROJECT DESCRIPTION

Mobile Robot (The Rug Warrior) project´s objective was to implement microcontroller programming for Motorola MC68HC11 µProcessor, and in this way, program the Rug Warrior (RG) to perform various actions of mobility.

RG was developed at the MIT labs. It is a battery operated robot with motors at each of its two wheels. It was equipped with sensors such as the Infrared sensor and the Photocells as well as shaft encoders at the wheels.

The objective was to make RG drive along a terrain, in straight lines or along a specified boundary, move around obstacles, move towards or away from a light source.

PROJECT ACTIVITY

After the Hardware assembly, the system programming was done in Interactive C (IC). The tasks were done one step at a time with the idea to make as many re-usable modules as possible.

The project lasted approximately 4 months, and at the end, RG could do all the tasks that it was assigned for this project. It was also programmed to scan its surrounding, fix a target, make a judgement based on the intensity of light source, or the distance from an obstacle, find a way past it, and still follow a fixed or a moving source.
