Evolution of Virtual Catapults
We describe the re-implementation of a system to evolve the morphology and behavior of artificial creatures, originally due to Karl Sims. The new implementation is fast, flexible, and allows for the evolution of a range of novel behaviors not previously seen in Sims’ or related work. In particular, we use off-the-shelf dynamics simulator engines that can be exchanged on the fly, and introduce a...
متن کاملEvolving Virtual Creatures and Catapults
We present a system that can evolve the morphology and the controller of virtual walking and block-throwing creatures (catapults) using a genetic algorithm. The system is based on Sims' work, implemented as a flexible platform with an off-the-shelf dynamics engine. Experiments aimed at evolving Sims-type walkers resulted in the emergence of various realistic gaits while using fairly simple obje...
متن کاملCapillary-inertial colloidal catapults upon drop coalescence.
Surface energy released upon drop coalescence is known to power the self-propelled jumping of liquid droplets on superhydrophobic solid surfaces, and the jumping droplets can additionally carry colloidal payloads toward self-cleaning. Here, we show that drop coalescence on a spherical particle leads to self-propelled launching of the particle from virtually any solid surface. The main prerequis...
متن کاملBoron effects on wall polysaccharide composition of marshmallow cells
Marshmallow is a medicinal plant containing mucilage polysaccharides and various phenolic acids. Boron (B) is an essential micronutrient whose necessity for plant growth and development has been attributed to its role in cell wall pectin network and maintenance of integrity and performance of membranes. The present study was aimed to investigate the effects of different concentrations of B (0.0...
متن کاملWait for the Second Marshmallow? Future-Oriented Thinking and Delayed Reward Discounting in the Brain
Our brains are equipped with the ability to mentally project us to the future so that we can explore potential actions and outcomes in advance. As Karl Popper famously said, we should ‘‘.let our false theories die in our stead’’ (Popper, 1963). Future-oriented thinking is indeed a basic operation of our proactive brain (Bar et al., 2007), and mental simulation serves the basis for many cognitiv...
