Besides the life-as-it-could-be driver of artificial life research there is also the concept of extending natural life by creating hybrids or mixed societies that are built from natural and artificial components. In this paper we motivate and present the research program of the project flora robotica. Our objective is to develop and to investigate closely(More)
The present investigation examines the changes in tyrosine kinase (Tyr-k) activity and tyrosine-specific phosphorylation of membrane protein(s) in isolated gastric mucosal cells from young (3 months) and aged (22 months) Fischer-344 rats after exposure to gastrin. In mucosal cells from young rats, a 15-min time course study revealed a steady rise of Tyr-k(More)

The self-organizing bio-hybrid collaboration of robots and natural plants allows for a variety of interesting applications. As an example we investigate how robots can be used to control the growth and motion of a natural plant, using LEDs to provide stimuli. We follow an evolutionary robotics approach where task performance is determined by monitoring the(More)
Captan (1,2,3,6-tetrahydro-N-trichloromethylthiophthalmide), a widely used fungicide, has been shown to induce carcinoma in the gastrointestinal tract of rodents. However, little is known about the captan induction of early biochemical changes in the gastrointestinal tract. The present investigation examines the changes in gastric mucosal proliferative(More)
In evolutionary robotics methods of evolutionary computation are applied to evolve robot controllers [1]. Evolutionary robotics is also our method of choice in the EU-funded project flora robotica [6, 8], which pushes research towards the evolution of a broad variety of artifacts and contraptions [4]. We are investigating how a distributed robot system and(More)
Self-organized construction with continuous, structured building material, as opposed to modular units, offers new challenges to the robot-based construction process and lends the opportunity for increased flexibility in constructed artifact properties, such as shape and deformation. As an example investigation, we look at continuous filaments organized(More)
Making the transition from simulation to reality in evolutionary robotics is known to be challenging. What is known as the reality gap, summarizes the set of problems that arises when robot controllers have been evolved in simulation and then are transferred to the real robot. In this paper we study an additional problem that is beyond the reality gap. In(More)
Mixing societies of natural and artificial systems can provide interesting and potentially fruitful research targets. Here we mix robotic setups and natural plants in order to steer the motion behavior of plants while growing. The robotic setup uses a camera to observe the plant and uses a pair of light sources to trigger phototropic response, steering the(More)
