Incorrectly specified or mis-specified cells often undergo cell death or are transformed to adopt a different cell fate during development. The underlying cause for this distinction is largely unknown. In many developmental mutants in Drosophila, large numbers of mis-specified cells die synchronously, providing a convenient model for analysis of this phenomenon. The maternal mutant bicoid is pa...

This paper describes the mechanical configuration of a quadruped robot firstly. Each of the four legs consists of three rotary joints. All joints of the robot are actuated by linear hydraulic servo cylinders. Then it deduces the forward and inverse kinematic equations for four legs with D-H transformation matrices. Furthermore, it gives a composite foot trajectory composed of cubic curve and st...

To find a solution of the inverse problem of electrocardiography as precisely as possible, individual geometry of a patient’s torso is required. The most precise method to obtain both the surface geometry and the position and shape of inner organs is an imaging method such as CT or magnetic resonance. In our work we tried to find a suitable surrogate torso model enabling to avoid the use of dem...

Passive Dynamic Walking (PDW) has been receiving increasing attention as a simple walking method with no or less control, therefore no or less energy consumption. To the best of our knowledge, there are no PDW models with a torso although there have been already many studies on PDW. This paper presents the first step towards applying the PDW principle to humanoid robots by adding a torso to a c...

Traditionally safety in industrial manufacturing environments has been addressed by rigid separation between robots and human operators. With the advent of new technologies transition production to industry 4.0, a more flexible approach is pursued achieve higher productivity, where operators are allowed collaborate interact. This transformation leads overcoming traditional procedures developmen...

Anterior terminal development is controlled by several zygotic genes that are positively regulated at the anterior pole of Drosophila blastoderm embryos by the anterior (bicoid) and the terminal (torso) maternal determinants. Most Bicoid target genes, however, are first expressed at syncitial blastoderm as anterior caps, which retract from the anterior pole upon activation of Torso. To better u...

We have previously shown that the Coriolis torques that result when an arm movement is performed during torso rotation do not affect movement trajectory. Our purpose in the present study was to examine whether torso motion-induced Coriolis and other interaction torques are counteracted during a turn and reach (T&R) movement when the effective mass of the hand is augmented, and whether the domin...

We developed very small and light sensors, each equipped with 3-axes accelerometers, magnetometers and gyroscopes. Those MARG (Magnetic, Angular Rate, and Gravity) sensors allow for a drift-free attitude computation which in turn leads to the possibility of recovering the skeleton of body parts that are of interest for the performance, improving the results of gesture recognition and allowing t...

The contribution presents an integrated system for automatic acquisition of a human torso model, using different input images. The output model consists of two free-form surface patches (with texture maps) for the torso and the arms. Also, the positions for the neck joint on the torso, and six joint positions on the arms (for the wrist, elbow and shoulder) are determined automatically. We prese...
