Abstract
The field of Robotics is ever growing at the same time as posing enormous challenges. Numerous works has been done in biologically inspired robotics emulating models, systems and elements of nature for the purpose of solving traditional robotics problems. Chromatic behaviours are abundant in nature across a variety of living species to achieve camouflage, signaling, and temperature regulation. The ability of these creatures to successfully blend in with their environment and communicate by changing their colour is the fundamental inspiration for our research work. In this paper, we present dwarf chameleon inspired chromatic behaviour in the context of an autonomous surveillance robot, “PACHONDHI”. In our experiments, we successfully validated the ability of the robot to autonomously change its colour in relation to the terrain that it is traversing for maximizing detectability to friendly security agents and minimizing exposure to hostile agents, as well as to communicate with fellow cooperating robots.

We present our chromatic behaviour experiments involving fellow robots, hostile and friendly agents using “PACHONDHI”, a real robotic platform
The aim of this research is centered on bio-inspiration for synthesizing rapid colour changing behaviours for security robots
Summary
The key for all the complex human problems is hiding in nature and we have to unearth it. If we traverse through the journey of natural evolution, we can come across plenty of evidence to the fact that living creatures have developed strong adaptive mechanisms and processes over millions of years, which offers a lot of potential for imitation into artificial models, systems and processes to solve our human problems. The Cerebrunnus rechenburgi spider is mimicked [4] by a reconfigurable quadruped robot mechanism and a new energy based control approach has been presented which can crawl, roll and transform between the two states. Another study [6] presents a spinal cord model and its synthesis in an amphibious salamander inspired robot demonstrating how a primitive neural circuit used for swimming locomotion can be extended by Robotics 2016, 5, 20; doi:10.3390/robotics5040020 www.mdpi.com/journal/robotics
