Robotic device and laboratory automation system comprising robotic device

A robotic device, the robotic device comprising:

• a stationary base;
• a first arm rotationally mounted on the base for rotation about a first axis (I);
• a second arm rotationally mounted on the first arm for rotation about a second axis (II), in which the second axis (II) is parallel to the first axis (I);
• a first driving device for driving the first arm to rotate about the first axis (I);
• a second arm drive unit with a second driving device for driving the second arm to rotate about the second axis (II), wherein the first driving device and the second driving devices are mounted stationary at and disposed in the base;
• and
• a linear drive unit for moving the first arm and the second arm in a direction parallel to the first axis (I) and the second axis (II), wherein the linear drive unit comprises a third driving device mounted stationary at and disposed in the base;
• wherein the first arm is mounted to the base by a first column driven to rotate about the first axis (I), wherein the first arm is non-rotatably, but axially displaceably along the first axis (I) coupled to the first column;
• wherein the second arm drive unit comprises a second column driven to rotate about the first axis (I);
• wherein the second arm is linked to the second column by a linkage system comprising at least one rod, which is rotatably about a rod axis (III) parallel to the first axis (I) and axially displaceably mounted on the second column and offset from the first arm and second arm;
• and
• wherein the linkage system comprises at least one cantilever, which is non-rotatably, but axially displaceably in the axial direction of the second column coupled to the second column and wherein the at least one rod is rotatably about the rod axis (III) and axially fixed coupled to the cantilever.
