MAUKA is a compact hexapod designed to position up to 5 kg payloads with a submicrometer resolution.
As a reminder, the hexapod is a platform with a parallel structure enabling very high precision positioning of objects in space according to the 6 degrees of freedom.
MAUKA hexapod offers travel ranges of 10 mm in X and Y, 20 mm in Z, and 16° in the three rotations. Its diameter is 107 mm and it is 198 mm height in mid position.
To minimize the diameter, we used a hexaglide geometry, where motors are mounted in line.
MAUKA hexapod operates in any direction: vertically, horizontally, or in any other angle. It is irreversible, even after a power failure.
Thanks to its absolute linear encoders, it is not necessary to carry out a homing command each time the controller is turned back on, the hexapod position is immediately known, without having to make any hexapod movement.
