Kosmos Cybernetic Hand with Functional Hydraulics 40cm

Kosmos Cybernetic arm with functional hydraulics. Length 40 cm. Colorful instructions for composition are included in the package. The bending of all 4 fingers is controlled by hydraulic pistons which are filled with water. All 4 fingers allow full range of flexion. 15 thumb positions (right thumb, left thumb and claw position, each position has five levels of rotation). Adjustable horizontal and vertical finger span (depending on the size of the object you want to grasp). The vertical span is adjusted by a yellow rotary dial on the top of the hand. The horizontal span is adjusted by pressing the fingers together from the sides or spreading them apart. Sliding palm position adjustment for comfortable operation. The load capacity when gripped with all fingers is 600 grams. The carrying capacity of one finger is only 60 g, so it is not recommended to lift objects with only one finger or to hang anything on the hand. Recommended age is 7+ with adult assistance, or 10+ without assistance. Only lift by the solid parts, do not pull on the water hoses. If air bubbles appear in the fists or there is not enough water, they can simply be removed from the hand and the water refilled via the hose.
