The vision system of our autonomous robot possessing the text plate detection and recognition abilities is the main equipment to capture surrounding information. By virtue of a PTZ camera, we can obtain the sequential images of indoor environments. As the autonomous robot moving forward, the obtained sequential images are fed to execute text plate detection. We analyze the color information in these...
Posture detection using Inertia Measurement Unit (IMU) has recently attracted great interests in healthcare research community. However, very few studies focus on the applications of this technology in the care of inpatients. This specific group of users, who are moderately to severely ill, have a distinct set of postures and activities that require special attentions and continuous monitoring from...
Transcranial magnetic stimulation (TMS) has been gaining popularity in various neurological treatments and an automated platform with better precision is desired. This paper proposes a dexterous articulated robotic arm with TMS coils as the end-effectors. Most robotic arm based positioning systems utilize vision feedback from stationary cameras for dynamic positioning, but these are not suitable for...
To fully complete the mission, it is essential for field robots to obtain the ability of overcoming various obstacles. Because of the various scale and shapes of the stairs, it is the obstacle which is the most easily access but hard to overcome. Therefore, stair climbing is essential to field robots. In this research, we set the climbing stairs with high stability at a high speed as our goal. The...
The technical approach of embedded shape memory alloy actuators (ESMAA) is presented herein. Three SMA springs are embedded in each silicone elastomer liquid at room temperature to form embedded SMA actuator rods used in designing a soft robot gripper. Just as human fingers make gestures to grab, so is the structure configured to perform humanoid gripping. Thus, this paper introduces the mechanical...
When the rigid-driven mode robots of wheeled, legged, crawler types operates in the narrow and non-structured environment, the energy consumption increase and the robot is difficult to pass through the obstacles which are smaller than itself. The sea cucumber, echinoderm animal, makes use of their body to produce variation-driven characteristics, like hydrostatic skeleton driving, which provides the...
The paper addresses the problem of creating a comprehensive fault injection environment, which integrates and improves various simulation and supplementary functions. This is illustrated with experimental results.
This paper introduces volume springs that provide the volume effect to a surface model when it is deformed. The estimation of the properties of the model takes the real material properties into consideration, where each spring stiffness is derived based on the elasticity, rigidity and compressibility modulus. The proposed model can be adopted to simulate soft objects such as a deformable human breast,...
When the interest operator is used as a feature extraction algorithm for face recognition, the algorithm may encounter the following problem: under complex imaging conditions such as varying facial expression, the feature extraction results of two corresponding blocks from two face images of the same subject may have low similarity. In order to address this problem, we propose a new algorithm in which...
