Robotic micro-nano-manipulation is currently achieved by installing a tool (gripper, etc.) on a supporting arm with several degrees of freedom. This solution has drawbacks because it is bulky, severely limits the work rate and struggles to perform precise manipulations at the micrometric scale.
The proposed invention consists of an original parallel robotic structure with 7 degrees of freedom (DDL) which incorporates within it a gripper for handling small objects. This robot is dextral thanks to these 7 DOFs which provide 3 rotations and 3 translations in space in addition to gripping. The structure is controlled by actuators placed on a fixed base allowing its miniaturization to scales of the order of one cubic millimeter. Precision is thus increased and the moving masses reduced to a minimum, which makes it possible to achieve very high work rates.
