ELT3170: Robotics Microprocessors

Students compare central processing unit (CPU) architecture of programmable robotics engineered systems and interface with analog sensors.

• Prerequisites: ELT1140: Robotics Applications, CSE3120: Object Oriented Programming 1

Theory

1. compare the internal architecture of various programmable robotics systems

• compare the difference in internal architecture between different robotics system microprocessors
• explain the differences between machine and assembly language and interpretive and compiler language
• explore the types of microprocessors used in at least three types of robotics systems

1. Analyze the engineering data of a programmable robotics system

• define the following terms:
  • microprocessor
  • input/output
  • instruction set
  • operand
  • mnemonic
  • opcode
  • data/address
• define and explain how the following are used in programming:
  • inherent, immediate and direct addressing
  • conditional and unconditional branching
  • stack operation/pointer, cascade, pop/push/pull instructions
  • subroutines
  • carry, negative, zero, overflow and flag operation
• explain the purpose of the following functional sections in a microprocessor:
  • input/output
  • accumulator
  • program counter
  • instruction decoder
  • controller
  • data register
  • address register
  • stack pointer
  • index pointer
• illustrate a block diagram of a microprocessor system showing its internal architecture
• define a machine cycle and explain how it impacts microprocessor programming
• explain how clock frequency affects microprocessor speed
• define how sensor input cycle relates to microprocessor speed
• describe the function of input interfacing
• explain how an analog input is interpreted by a microprocessor

1. Create a transitional strategy to accommodate personal changes and build personal values
   • identify short-term and long-term goals
   • identify steps to achieve goals

Practical

1. Build and program a robot to accomplish specified tasks

• write and execute programs that use analog and/or digital input devices
• solve a design problem and build a programmed robotics system incorporating the solution
• program a robotics system using one digital input and calculate the machine cycles required for a programmed robotics system to complete a task given a digital input device
• program a robotics system using one analog input and calculate the machine cycles required for a programmed robotics system to complete a task given an analog input device
• program a robotics system using one analog input requiring an interface and calculate the machine cycles required for a programmed robotics system to complete a task
• build, program and verify the operation of a robotics system that uses at least one sensor interface to perform a specified task
