Due to the dexterous manipulation capability and low metabolic energy consumption property of the human hand, many robotic hands were designed and manufactured that are inspired from the human hand. One of the technical challenges in designing biomimetic robot hands is the control scheme. The control algorithm used in a robot hand is expected to ensure the tracking of reference trajectories of ...

The disadvantages caused by the swing of a fish body were analyzed. The coordinate system of a two-joint robot fish was built. The hydrodynamic analysis of robot fish was developed. The dynamic simulation of a two-joint robot fish was carried out with the ADAMS software. The relationship between the swing of fish body and the mass distribution of robot fish, the relationship between the swing o...

This paper introduces MiRo the world’s first commercial biomimetic robot and describes how its vocal system was designed using a real-time parametric general-purpose mammalian vocal synthesiser tailored to the specific physical characteristics of the robot. MiRo’s capabilities will be demonstrated live during the hands-on interactive ‘Show & Tell’ session at INTERSPEECH-2017.

In this paper, the suspension control of a Robot Fish with two 2-DOF pectoral fins, a caudal fin and a volume regulator is introduced. Because the diving depth of the robot fish is related to its volume and the hydrodynamic forces acting on its body, the suspension control is implemented by regulating the attack angle of pectoral fins and the volume of the robot fish body. The attack angle of p...

It is our purpose to develop an underwater microrobot that has the characteristics of flexibility, driven by a low voltage, good response and safety in body. We have reported an underwater fish-like microrobot with 2 DOF that has the characteristics of flexibility, good response and safety in body before. In this paper, we propose a new prototype model of an underwater microrobot utilizing ICPF...

Weakly electric fish use electric organ discharge (EOD) and their electroreceptors to identify prey, explore their surroundings, and communicate with other members of the same species. They are specialized in active electrolocation using a self-generated electric field, and they can sense distortion of their self-generated electric field caused by a target object. Electric fish have many electr...

Biomaterials are evolving quite rapidly over the last decade. Many applications have been considered toward their involvement in saving lives line of duty for law enforcement agencies and military operations. This article discusses recent work on role biomaterials that can be as a competitive alternative to composites, being used against ballistic impacts. The fish-scaled focused this paper, hi...

This paper describes preliminary experiments with an EAP (electroactive polymer) robot. The research reported here serves two purposes. First, we aim at building a testbed to investigate control methods of EAP actuators. Second, we wish to build an underwater robot that mimics undulating motions of pectoral fins. The prototype described in this paper has two pectoral fins. The tests confirm tha...
