- 1. INTRODUCTION TO ROBOTICS AND MICROCONTROLLERS Instructors: Tijjani “TJ” Mohammed and Tarek Abdel-Salam
- 2. Module Overview A general overview of what robots are, and the essential components embedded within Relevant examples of microcontroller and robot applications to help the participants understand contexts and applications of these technologies Contextual understanding makes it easier to relate programming efforts to basic science, math, or engineering concepts
- 3.

- 4. Teacher objectives Upon completion of this module instructors should be able to: Prepare a presentation on the fundamentals of microcontrollers and robotics Explain to students the basic building blocks of microcontrollers including the CPU, memory, and input/output. Explain number systems and their usefulness in robotics and computing Walk students through the process of constructing and testing a robot
- 5. What is a Microcontroller? A microcontroller is a kind of miniature computer that found in all kinds of gizmos Generally speaking, if a device has buttons and a digital display, chances are it also has a programmable microcontroller brain.
- 6. Microcontrollers cont. Microcontrollers are 'single chip' computers specifically designed to: Read input devices, such as buttons and sensors Process data or information Control output devices, such as lights, displays, motors and speakers
- 7. Microcontrollers are placed in devices, or embedded, for operation and control. Can you name other devices in your life that have embedded control? Embedded Control
- 8. Microprocessor vs. Microcontroller A microprocessor is the “brain” of a computer system Generally referred to as the central processing unit (CPU), the microprocessor by itself is practically useless To be useful, one must have means of communicating with it using input and output devices One must also add memory (ROM and RAM) so that the system can be programmed.
- 9. Microprocessor vs. Microcontroller Cont. A microcontroller is a computer chip designed for control-oriented applications Unlike ordinary microprocessors, microcontrollers have built-in features that make them operate almost independent of additional circuitry This is possible because microcontrollers contain things like memory (ROM, EPROM, RAM, etc) input and output ports timers serial and parallel communication capability analog-to-digital converters
- 10. The BASIC Stamp 2 embeds a microcontroller, the PIC16C57, on a module to make programming and use very simple, yet very powerful. Additional components on the module provide everything needed to systems and applications, like robotics. Boe-Bot’s Brain: The BASIC Stamp
- 11. BASIC Stamp Module Components 5V Regulator Regulates voltage to 5V with a supply of 5.5VDC to 15VDC Resonator Sets the speed at which instructions are processed. EEPROM Stores the your PBASIC program. Interpreter Chip Reads the BASIC program from the EEPROM and executes the instructions. Serial Signal Conditioning Conditions voltage signals between PC serial connection (+/- 12V) and BASIC Stamp (5V) for Programming.
- 12. So What is a Robot? A robot is a machine that gathers information about its environment (senses) and uses that information (thinks) to follow instructions to do work (acts) The “sensing” part provides input to the robot through switches, light sensors, The thinking part is the microcontroller brain The acting part could be through lights, motors, actuators, sounds, etc
- 13. Robots and Applications Robots come in many shapes and sizes
- 14. Ecological Data Collection EME Systems Undersea Research Harbor Branch Institute JP Aerospace Test Launch High-Tech and Aerospace use
- 15. Fundamentals of Electricity Electric Current (I), measured in amperes (A) Resistance (R), measured in Ohms (Ω) Voltage (V), measured in volts (V) A complete path or circuit is required for current to flow R V I
- 16. Fundamentals of Electricity Cont. Robotics requires a basic understanding of electricity and simple wiring diagrams The relationship between current, voltage and resistance is expressed by what is known as Ohm’s Law, variations of which are expressed below: V = IR; I = V/R; R = V/I R V I +V R + -
