The importance of mobile robots for the nuclear disaster response has been realized after Fukushima Dai-ichi nuclear power plant accident. In this paper, we propose a tracked robot for rescue and search in nuclear environment. A gamma-ray irradiation test of the robot's control system is conducted, in order to evaluate the performance of the robot in nuclear environment. The parallel test method is...
Compared to robotic injection of suspended cells (e.g., embryos and oocytes), fewer attempts were made to automate the injection of adherent cells (e.g., cancer cells and cardiomyocytes) due to their smaller size, highly irregular morphology, small thickness (a few micrometers thick), and large variations in thickness across cells. This paper presents a robotic system for automated microinjection...
An Image-based visual servo system is presented for a bionic spherical parallel mechanism to minimize a tracking error function to analog smooth pursuit of human eye, which is also called eye-in-hand visual servoing, capable of tracking moving target. More specially, we propose a real-time moving target tracking algorithms which utilizes perceptive image hash based on Discrete Cousin Transform, collaborative...
This paper proposes a robotic eye based on spherical parallel mechanism with three degrees of freedom. It aims to imitate the human eye with active vision for robots in various unstructured environments. Its kinematic analysis and performance estimation indexes are presented. For the pursuit of best velocity and acceleration accuracies of the eyeball, an optimal design method using evolutionary strategy...
Combined the driving features of the spherical robot with Internal-Driven and Wind-Driven and took the special environment into account, this paper proposes a spherical robot structure with Mixed-Driven, both Internal-Driven and Wind-Driven, which is mainly consists of a flexible spherical shell and a drive module. The robot can be driven by the wind, as well as improve the capability of climbing...
Eccentric paddle mechanism based on epicyclic gear mechanism (ePaddle-EGM) is a novel locomotion mechanism designed for amphibious robot. The epicyclic gear mechanism is the key component of ePaddle-EGM to perform multiple gaits. In this paper, efficiency of the epicyclic gear mechanism is analyzed. Via the virtual power flow, we characterize how the efficiency relates with the velocity ratio and...
Firstly, based on the principle of binocular vergence eye movements ,a new type of method about field fixed point landing of the Subminiature robot helicopter is put forward. Secondly, according to oculomotor neural pathways, the oculomotor control system model is established. Then the control model of SHR landing system is discussed in detail. Some key problems about the control system are stressed...
