MTRX1705: Introduction to Mechatronic Design

This unit of study aims to provide an introduction to the basic hardware elements of mechatronic systems. Basic electrical theory: Ohms law, Kirchoff's voltage and current laws, passive component characteristics (resistors, capacitors and inductors). Number systems and codes; Logic gates and Boolean algebra, universal (NAND) logic gates; Digital arithmetic: operations and circuits, Two's complement addition and subtraction, overflow; Combinational logic circuits; Flip-flops and related devices; Counters and registers, shift register applications; sequential circuits, designs of synchronous, cascadable counters (BCD and binary). Integrated circuit logic families and interfacing; practical issues including, fan out, pull-up/down, grounds, power supplies and decoupling; timing issues, race conditions. Tri-state signals and buses; MSI logic circuits, multiplexers, demultiplexers, decoders, magnitude comparators; Introduction to programmable logic devices. Brushed DC Motors: Introduction to characteristics and control, motor specifications, torque-speed characteristics, power and efficiency, thermal considerations. Introduction to BJTs and FETs as switches. PWM control of DC motors; half- and full-bridge configurations; Feedback and operational amplifiers; selected op-amp applications circuits with an emphasis on sensor and actuator interfacing. The unit of study will include a practical component where students design and implement logic and linear circuits. Purchase of a basic laboratory tool kit as described in classes will be required.
