Moving Through The World

Question 1

Affordances

Answer 1

The world affords actions

Question 2

Resonance

Answer 2

The brain is tuned to resonate with particular environmental patterns

Question 3

Invariants

Answer 3

Our view of objects is never still
Their properties change as we move
But always in the same way
Eg.texture gives relative depth

Question 4

Gibson

Answer 4

Direct, bottom up perception

Sensory ecology affords actions

Question 5

Pole of expansion

Answer 5

Point of flow field that doesn’t move

Where you’re heading

Question 6

Why build robots?

Answer 6

To test models

To do a job

Question 7

Two approaches to biorobotics:

Answer 7

Engineering: might learn something in the process of building

Algorithmic: can test algorithms derived from behavioural studies

Question 8

What can we learn from insects about robotics?

Answer 8

How to make robots with similar manoeuvrability

Question 9

Insect control mechanisms are:

How do insects simplify tasks?

Answer 9

Matched to natural interactions with environmental

Behaviour and ecology constrain the stimuli it encounters

Question 10

Flow field for a movement

Answer 10

The sum of the flow field of each of the movements components

Can combine two movements to provide info about movements that have just been made
