Summary

Robotic sensing gives robots information about their surroundings and their own interactions with the world. This lesson introduces the role of sensory feedback, then focuses on vision and touch as ways robots perceive and respond to their environments.

Robotic sensing is the branch of robotics concerned with giving robots the ability to detect and interpret information. A robot can use sensed input as feedback: it compares what it detects with what it should detect and adjusts its behavior accordingly.

All flashcards

What is robotic sensing?
The area of robotics that enables robots to detect and interpret information about their surroundings and interactions, often using it as feedback to adjust behavior.
What are sensation, estimation, and matching?
Three broad sensing procedures: detecting input, estimating relevant information, and comparing the result with a reference or goal.
How can image fusion help a robot?
Wavelet-transform methods can combine images captured at different spectra or focal settings, providing more accurate information for robot decisions.
What does an adaptive tactile filter do?
It predicts sensor signals caused by the robot's own movements and screens them out to help distinguish external contact.
Which four features can be used to categorize touch patterns?
Force, contact time, repetition, and changes in contact area; these features can help associate patterns with human emotions.

Quiz questions

  1. How can combining acoustic and linguistic features affect speech-emotion recognition?Answer: It can improve recognition compared with using either feature set alone.
  2. How can a two-microphone system help locate instructional speech?Answer: It compares signal strengths from the microphones to estimate the speech direction.
  3. Why can chemical reactions guide motion in some molecular-scale robots?Answer: Individual molecules cannot store complex motion programs, so reactions can guide their movement.
  4. What does magnetoreception allow a robot to sense?Answer: Magnetic fields.
  5. What are remote senses in robotic systems?Answer: Arrangements in which sensing occurs away from the node that interprets or computes the data.
