Voxelization methods are extensively employed for efficiently processing large point clouds. However, it is possible to lose geometric information and extract inaccurate features through these voxelization methods. In this letter, we propose a novel, flexibly-shaped Read more…
This work proposes newly an incremental motion learning algorithm through kinesthetic teachings and a new motion production algorithm by combining learned motions in a humanoid robot. The proposed algorithms are useful to enrich producible motions Read more…
This work presents a design of a thermal SMA based simple small-sized and low-weight crawling robot, mimicking the crawling motion mechanism of Caenorhabditis elegans (C. elegans). Properties of the thermal SMA are similar to those Read more…
We investigate a new algorithm for real-time 3D human-motion tracking through a monocular camera. The algorithm is based on body-silhouette shape matching combined with particle-filter-based selected-region tracking in the 2D view. The selected-region tracking, combined Read more…
This work investigates mechanisms for active flapping and twisting of robotic wings and assesses flying effectiveness as a function of twist angle. Unlike the flapping motion of bird wings, insects generally make a twisting motion Read more…
This work presents the mechanical human gait-based 3D bipedal walking robot. The robot mimics human walking through the push-off mechanism at the ankle, the passive knee bending mechanism, and the simple lateral balance control. To Read more…
This work proposes an algorithm for real-time navigation of a humanoid robot with a stereo vision but no other sensors. Using the algorithm, a robot can recognize its 3D environment by retrieving SIFT features from Read more…
