In this study, we propose a Bernoulli suction-type non-contact manipulator that can attract an object and simultaneously change its in-plane position and orientation while holding it. The proposed manipulator consists of a suction plate equipped with six compressed-air nozzles. By ejecting compresse
This paper proposes a novel force feedback system based on visual processing and Moiré patterns. The system uses a force sensor with a simple and efficient structure to eliminate the need for cables or other electronic components. A brass flexure plate was employed as the primary elastic element, le
A lightweight and high-output manipulator is introduced in this letter. The manipulator comprises two parts: a robot hand part and a wrist part. The total weight of the robot hand part is approximately 450 g, and its size is almost the same as that of a human hand. Furthermore, a design concept of a
Landing is an essential part of multicopter task operations. A multicopter has relatively stringent requirements for landing, particularly for achieving flatness. Currently, landing on rough terrain with normal skids is difficult. Therefore, research is being conducted to obtain skids capable of lan…
In recent years, vision-based analysis systems of micro-objects in a microchannel have been actively developed. However, it is difficult to focus on high-speed micro-objects in a microchannel because the general height of a microchannel is approximately 10-100 μm, whereas the depth of focus of the o…
This paper proposes an intelligent and fast tracking method for robust trackability against appearance changes. The method hybridizes a correlation-based tracking algorithm operating at hundreds of frames per second (fps) with a deep learning-based recognition algorithm operating at dozens of fps. A…
In this paper, we propose a design method for the mechanism of a robotic arm suitable for a multicopter. The motion of an arm attached to a multicopter can possibly disturb the multicopter attitude. Our aim is to suppress this attitude disturbance by mechanical methods. In the proposed design method…
Recent progress in LOC technology have made it possible to analyze cells in microfluidic devices in a microscopic environment. Vision-based cell analysis systems have a limitation in their analysis range owing to the small view area of the microscopic objective lens; thus, an expansion of the view a…
The research field of nongrasping manipulation is a maturing area in robotic motion control. However, the common principles of motion planning for nongrasping manipulation systems have not yet been established. This paper proposes the concept of virtual connecting manipulation as a generalized motio
We propose a novel scheme for manipulating a passive object using an active plate. The objective of this study is to control an object's orientation with respect to the gravitational force direction by using an active plate for realizing hitherto unrealized object motion. In this context, motions of…
Flower stick juggling is a dexterous task done by skillful jugglers. We aim to realize dexterous tasks done by humans using robotic systems. This work focuses on flower stick juggling and proposes a feedback control strategy for a flower stick juggling task called “propeller” as one of the robotic d…
