We propose a new neuro-robotic network that can simultaneously achieve a goal oriented behavior task and perception enhancement task for a visually-guided object manipulation based on learning by examples. The brain exploits action to develop perception qualities, and perceptual process helps to develop qualified-behavior. In order to import those action and perception inter-abilities of a brain into a humanoid robot, we consider two key inspirations: 1) Sensory Invariant Driven Action (SIDA) and 2) Object Size Invariance (OSI) characteristic. Considering robot manipulation of a target object with distance estimation as a perceptual process, we develop a new autonomous learning method based on the SIDA for behavior generation and OSI property for perceptual judgment. The proposed method is evaluated by using a humanoid robot (NAO) with stereo cameras, and the experimental results show that the proposed method is effective on autonomously improving the behavior generation performance as well as depth perception accuracy.

Knowledge management is seen by many to be a prerequisite for the successful organization. As a multidisciplined approach to achieving organizational objectives by making the best use of knowledge, its gaining value had been recognized by more organizations and adopted to leverage business efficiency and effectiveness. Exploring the importance of knowledge management in the new businesis enviroemnt s of great necessity and therefore will bring significent evolution to the operation.

A type of tactile sensors based on piezoresistive principle is designed for the robot grab force detection and control. According to human behaves and awareness, the robot grabbing control program imitate human hand grasp active perception and action mechanisms. With the tactile sensors, the slip and grasping process pressure signal is sampled and analysed by general time-domain statistical parameters, and a simpler control algorithm is researched. In the experiment the robot has accomplished soft grabbing by modeling human hand action and applied appropriate grabbing force on objects of different weights or material by means of the control algorithm. Experiments suggest that this sensor and active biomimetic process is suitable to be used in the tele-presence technology application in the case of the visible range or visual equipment aid especially.

Creating descriptors for trajectories has many applications in robotics/human motion analysis and video copy detection. Here, we propose a novel descriptor for 2D trajectories: Histogram of Oriented Displacements (HOD). Each displacement in the trajectory votes with its length in a histogram of orientation angles. 3D trajectories are described by the HOD of their three projections. We use HOD to describe the 3D trajectories of body joints to recognize human actions, which is a challenging machine vision task, with applications in human-robot/machine interaction, interactive entertainment, multimedia information retrieval, and surveillance. The descriptor is fixed-length, scale-invariant and speed-invariant. Experiments on MSR-Action3D and HDM05 datasets show that the descriptor outperforms the state-of-the-art when using off-the-shelf classification tools.

In this paper, a six-legged walking robot inspired by insect locomotion is discussed. To implement the walking pattern of insects, four-bar linkage based structure is proposed and its performance is analyzed by kinematic simulation. Two servomotors are applied to left and right sides of the robot, which allows smooth turns and a natural walking pattern by the phase difference between two motors. The main structure of the robot is manufactured by a rapid prototyping method with polypropylene material, and a micro camera is installed for real-time video transmission to show its potential applications.
