They are developing humanoid robots.
Nowadays, the hardware realization still restricts the general improvement of humanoid robot developments, especially the minihumanoid robots.
This characteristic differentiates humanoid robots from industrial robots in design concepts.
By changing the configuration along the self-motion curve a humanoid arm can increase its rigidity or compliance and can gain mechanical advantage near kinematic singularities.
Most of the available humanoid prototypes have a high number of degrees of freedom, a complex control and a high cost.
The biped humanoid robot has forty-three mechanical degrees of freedom and four passive degrees of freedom (a translational motion and three rotational motions).
At the same time, work on humanoids has been almost considered as mere enthusiast's concern.
As a consequence, researchers study a variety of tasks performed by humans and are trying to accomplish these tasks with a humanoid or service robot.
Besides, in some cases posture is understood as a certain relative fixed position of humanoid links that move as a whole.
