Examples of problems that can be solved with evolutionary robotics
Sensing ( Vision ), Controll and Planning, Design
Give examples of evolutionary robotics in Controll and Planning
Path planning, Task planning
Give examples of evolutionary robotics in design
Robot body shapes ( complex designs ), or connections
What is the evolutionary algorithm ?
Init random population - > evaluate individuals -> criteria reaches? - > if not make new population from good individuals - > if problem solved!
What desides the probability of a individuals survival chances?
The fitness value
What is a fitness value ( evolutionary robotics )
A meassure of an individuals ability to solve a given task
Do evolutionary algorithms guaranty an optimal solution?
No
In EA what do we mean by black-box ?
That the algorithm does not assume knowledge of the problems.
What is EA on a real robot not a good idea?
Time consuming, mechanical tear, needs supervision
Why do we use EA in simulations? What can be a problem with simulations?
Allows automated evalution, can be faster. A big reality gap can be a problem
What is Robot studios ?
An exact copy of ABB robots used for simulation. All variables given are applicable in the real world.
Name the two types of sensors?
Active ( projects energy to sense ), Passive ( uses surrounding energy to sense)
Whats the differense: Proprioceptive/ Exteroceptive
Prop - internal state of robot, Ext - the world around the robot
Name some proprioceptive sensors
thermometer, gyroscope, accelerometer
Name some exteroceptive sensors
camera, compass, gps, contact sensor, sonar, lasers
