Virtual life projects

Here are some possible topics for experiments for the Virtual Life course 2005. The topics included here are just indications and not predefined research projects. The literature in the 'suggested readings' is not intended as an extensive overview of the field, but nevertheless provide some interesting references. To get an overview of the literature of a field, you can go through the reference-sections of the various articles.


 

 

Animal Locomotion

Introduction
Any legged device that moves through it a natural environment must solve some hard mechanical and control problems, whether it is made of living tissue or metal. Therefore, one can both learn to understand animal movement and to design legged robots by working on both issues at the same time.

The locomotor system of slowly walking insects is well suited for coping with highly irregular terrain and therefore might represent a paragon for an artificial six-legged walking machine.

Animal Locomotion

Creatures
Legged walkers and swimmers constructed in the standard arsenal of Framsticks creatures with bend and rotation muscles. Creatures are most often controlled by neural networks that mimic biological neural mechanisms.

Modelling and Projects
Experiments in animal locomotion are likely to involve the construction of biologically plausible neural mechanisms. This includes different types of networks (e.g. spiking neural network, cyclic topological networks, pattern generating networks, etc.). Imporant also is the exploitation of physical features of the creatures morphology (in interplay with its neural control system).
Project in this area do not focus on evolutionary processes. However, the training for the neural networks is often done through exogenous evolution (i.e. standard GAs).

  • Salamander (swimming and walking) locomotion This project investigates the transition from swimming to walking during vertebrate evolution. We study whether neural controllers for swimming similar to those of the lamprey can be extended to control both the swimming and walking of the salamander. The salamander is indeed believed to be one of the modern tetrapods closest to the first vertebrate having made the transition from aquatic to terrestrial habitats during evolution.
