Autonomous embedded systems design

Presentation

Programme (detailed contents):

Due to embedded system constraints linked to the application, two applications are detailed:

• complete design an autonomous mobile robot able to move and communicate with other robots.

• design of an automotive application (body control) with sensors, microcontrollers, smart power actuators, communication bus, LCD display, system basis chip, in partnership with NXP.

The themes are:

- Management / Storage / energy recharging.

- Automotive electronics modern power boards, computers communication bus, LCD display, system basis chip

- Architectures and protocols of the various buses (wired and wireless)

- Architectures multi-source voltage (interface and translation of logic levels)

- Motor control

- Instrumentation and reconfigurable architectures for sensor signal conditioning

- components to ensure safety and robustness

Organization:

Mixed between lectures and Project based learning

Lectures are made by different industry stakeholders, each with a special skill and working in order to give students the latest advances in automotive electronics.

Projects allow students to work in a very close conditions that they will find in the industry.

For the design part of a mobile robot, it is ensured by leading researchers in the field of embedded electronics.

Objectives

At the end of this module, the student will have understood and be able to explain (main concepts) main subsystems as follow:

- Energy Management:

                * architectures converters (DC-DC, LDO, Band-Gap ...)

                * Storage and charging architectures (Lipo, Li-ion ...)

* Management of low-power modes of a microcontroller

- Interfacing:

            * between logic levels (strong currents, voltage levels,                            EMC, thermal protection, ...)

            * between the microcontroller and peripherals based on the waveform of the current• with power actuators (smart MOS)

-Communication:

            * protocols: I2C, SPI, CAN, OneWire

                * RF protocols: XBee, 868MHz, 433MHz RFID

- On board intelligence:

                * Reconfigurable digital and analog architectures (3 bit microcontroller, FPAA)

- Display:

                * Automotive Dashboard

                * Screens / touchscreens

- Safety and robustness:

                * analysis of safety

                * System basis chip, power supply supervision

                * Watchdogs, error and fault diagnosis

                * EMC requirements

The student will be able to devise from specifications all the subsystems architectures and choose components to assume a design complies with the specifications (battery and electronics management, connection of selected cards and constraints for microcontrollers programming).

Note that analog design will be provided on  
FPAA.

Form of assessment

The evaluation of outcome prior learning is made as a continuous training during the semester. According ot the teaching, the assessment will be different: as a written exam, an oral exam, a record, a written report, peers review...
