Study Notes
Robot Components
- Common actuation types include servomotors, stepper motors, pneumatic actuators, and hydraulic actuators.
- Sensors mimic human senses (sight, touch, hearing, taste, smell) and gather information about the robot's environment and internal state.
- Sensor devices enable robots to interact effectively with their surroundings, such as vision systems and tactile sensors.
Control and Processing
- The controller functions like a cerebellum, managing the robot's movements based on sensory feedback, though less complex than a brain.
- The processor acts as the robot's brain, calculating joint motions necessary for desired actions and ensuring synchronized performance between the controller and sensors.
Software
- Three main software types are involved:
- Operating systems that run the processor.
- Robotic software that applies kinematic equations for joint motion.
- Control software that integrates data from sensors and executes commands.
Limitations of Robots
- Despite advanced sensing capabilities, robots face challenges in cognition, creativity, real-time decision-making, and dexterity.
Cost of Robotics
- Robots are expensive due to initial equipment costs, installation, integration into existing processes, peripheral necessities, training, and programming requirements.
Robot Classification
- Fixed-sequence robots execute tasks via predetermined methods with limited flexibility.
- Playback robots learn tasks by recording human movements for future repetition.
- Numerical-control robots function from a supplied movement program rather than manual teaching.
- Intelligent robots can adapt and perform tasks effectively amidst changing environmental conditions.
Robotic Components
- Effectors serve as robotic appendages that interact with the environment, such as arms and wheels, facilitating movement and manipulation.
- Robot manipulators, essentially robotic hands and arms, represent a significant focus in current robotics research.
- Perception involves sensors and algorithms enabling robots to interpret environmental signals.
- Control systems provide a robot's central command, analogous to a nervous system, coordinating operations for intelligent behavior.
- Communication systems allow robots to exchange information with operators or other entities.
Robot System Elements
- A robot is a cohesive system featuring multiple elements:
- Manipulator or rover, which includes the structural components like links and joints.
- End effector, attached to the manipulator's last joint for handling tasks or objects.
- Actuators function as the robot's muscles, responding to signals from the controller to execute movement of joints and links.
