On-line evolution

We recently finished our proof-of-concepts experiments with on-line evolution. In on-line evolution a human trainer drives the robot and while the robot is being driven it is learning (via an evolutionary algorithm) to imitate the human’s control behaviors. After a … Continue reading

COTS Bots Project at the University of Idaho

We, students and faculty at the University of Idaho, are designing and building robots according to the COTS principle – e.g. using Commercial Off-The-Shelf products. Critical design requirements are that the robot be: Affordable (<$500) Easy and quick to assemble (e.g. … Continue reading
