Flapping flippers or fins are widely employed in biomimetic and bioinspired aquatic robots that imitate natural swimmers, such as fish dolphins. This article involves robotic biomimetics of the penguin, which is often overlooked an excellent swimmer benefiting from agile wings. To achieve equivalent swimming skills robot, wing motion a real penguin was investigated. Based on findings, we develo...

From the study of biological acoustic sensorimotor systems it can be seen that Doppler is a rich source of information which is not exploited by commercial ultrasonic range sensors such as the Polaroid. In this work we present a simple collision detection and convoy controller for RoBat, a mobile robot provided with a biomimetic sonarhead, based on the presence or absence of Doppler shifts in t...

Palm sized legged robots show promise for military and civilian applications, including exploration of hazardous or difficult to reach places, search and rescue, espionage, and battlefield reconnaissance. However, they also face many technical obstacles, includingbut not limited toactuator performance, weight constraints, processing power, and power density. This paper presents an overview of s...

There is increasing interest in the use of animal-like robots in applications such as companionship and pet therapy. However, in the majority of cases it is only the robot’s physical appearance that mimics a given animal. In contrast, MiRo is the first commercial biomimetic robot to be based on a hardware and software architecture that is modelled on the biological brain. This paper describes h...

The development of a wireless undulatory tadpole robot using ionic polymer–metal composite (IPMC) actuators is presented. In order to improve the thrust of the tadpole robot, a biomimetic undulatory motion of the fin tail is implemented. The overall size of the underwater microrobot prototype, shaped as a tadpole, is 96 mm in length, 24 mm in width, and 25 mm in thickness. It has one polymer fi...

We describe the locomotion dynamics of a biomimetic robot and compare them with those of its exemplar: the cockroach. The robot is a small (0.275kg) hexapod created using a layered manufacturing technique that allows us to tailor the compliance and damping of the limbs to achieve passive stabilization similar to that observed in insects. The robot runs at over 3 body-lengths per second (55 cm/s...

We discuss the development and design of a Biomimetic Electrostatic Imaging (BEI) element for use in a future multichannel imaging instrument. Inspiration for electrostatic sensing is provided by the diverse species of fish that use passive and induced electric fields for hunting, defense, localization, and communication. Designing an electrostatic sensor is not without its challenges. Hardware...

Many aquatic organisms swim by means of an undulating fin. These undulations often form a single wave travelling from one end of the fin to the other. However, when these aquatic animals are holding station or hovering, there is often a travelling wave from the head to the tail, and another moving from the tail to the head, meeting in the middle of the fin. Our study uses a biomimetic fish robo...

Biomimetics can be expressed as biologically inspired mechanical devices. The term of itself is derived from bios, meaning life, and mimesis, meaning to imitate. This thesis deals with biomimetic approaches for controlling nonholonomic mobile robot. It obtains three techniques of such biomimetic approaches. They include adaptive actor-critic algorithms, feedforward and feedback techniques. The ...
