In this paper, mechanical design and implementation of a low-cost and lightweight inflatable robot finger are proposed. The proposed soft inflatable robot finger is different from traditional designs. It uses a common and low cost inflatable material and can be easily and massively manufactured. The proposed soft inflatable finger only weighs 0.8 grams, but can well realize swift movement which is...
Chinese calligraphy is a unique form of art in the world, whose aesthetic is mainly created by the proper manipulation of the brush. However, it is impossible for a person to figure out the 6-D motion of the brush from calligraphy images, if he has no experience of writing calligraphy. In this paper, we propose a Learning from Demonstration approach for our calligraphy robot, Callibot, to acquire...
Known as “the art of strokes”, Chinese calligraphy expresses its aesthetic through the strokes. A calligraphy learner practise the strokes and compose a calligraphic character by the strokes thereafter. Following the same process, the calligraphy robot, Callibot [2] needs to extract the strokes from a character. Therefore, we propose an approach to extract strokes using the geometric properties on...
In this paper, a novel soft inflatable arm is proposed for telepresence robots. It is capable of imitating human arms to realize remote interaction. The new proposed arm using a very common and low cost inflatable material, and it is very light, which weight is only about 50 grams, but can well realize agile movement by driving three tiny cables installed in shoulder joint and elbow joint, respectively...
In this paper ceiling affixed ARToolKitPlus 2D code artificial landmarks are evaluated for purposes of robot localization and navigation. Ceiling affixed codes rarely come in contact with people, equipment or robots, and for this reason they are more likely to stay detectable over a longer period of time. Multi threshold averaging, light gradient compensation and neighbourhood search techniques further...
As one of the most unique types of art in Chinese culture, nowadays Chinese calligraphy is attracting increasing interests from researchers. It will be a big step if we have a robot to write Chinese calligraphy, especially in various styles, and it will form a bridge to combine science with art directly. However, there are so many different types and styles in Chinese calligraphy, and to distinguish...
In this paper, we present a novel frame climbing robot, called Frambot which aims to climb on non-enclosable rectangular trusses. Frambot weighs only 1.6kg and consists of two grippers connected by a body linkage. For the grippers of Frambot, it provides not only the grasp on a truss structure, but also allows a linear truss climbing motion. Based on the mobility of Frambot, we propose new climbing...
In this paper, an novel tree gripping mechanism has been proposed for miniature tree-climbing robots. It is capable of attaching on a wide variety of trees with a wide range of gripping curvature. In addition, it is lightweight and simple in control. The gripper is simple in control as it is actuated by one actuator only. In addition, the omni-directional gripping ability also simplifies the use of...
The paper proposes a dancing robot based on the beat tracking method. The robot can carry out different actions when receiving different musical signal input. The dancing poses are vivid and lifesome, and development of the robot is helpful to enhance intelligence of the traditional creational robot, which exerts a striking influences on the conventional toy market. In the paper, the design of the...
Traditionally, path planning for robots is modeled as optimization problems. One of the most commonly used optimization strategies is Genetic Algorithm (GA) since it always guarantees a nearly shortest path even a global path can not be obtained within a reasonable time. In fact, the performance enhancement of GA is still an open topic for researchers by designing different genetic operators. In addition...
The aging of population has become a social problem and fall is a major health risk in the elderly. To this end, this paper presents a novel approach for fall detection applied to an intelligent household surveillance robot. Silhouette based features are extracted, including aspect ratio of minimal bounding box of the human silhouette, approximated elliptical eccentricity, normalized central moments...
In many societies, the aged people are often living alone. For the aging population, surveillance in household environments has become more and more important. In this paper, we present a household surveillance robot that can detect abnormal events by utilizing video and audio information. In our approach, moving targets can be detected by the robot with a passive acoustic location device. Then the...
Recently, development of mini-sized humanoid robots with a certain level of intelligence becomes a popular research topic. Because of its small size and light weight, those humanoid robots become more portable and attractive. However, extra difficulties are introduced in hardware selection, mechanical design, motion planning, etc. In this paper, we propose the development of a transformable mini-humanoid...
Language plays an important role in human and household service robot communication, and speech not only contains semantic information, but also involves the tone and emotion information of speakers. We have developed a chatting robot prototype which can use speech to communicate with users. The semantic information are used to produce response by this robot. However the emotion information is also...
