What are the disadvantages of robotic arms

Hexapod robot

Hexapod robot are industrial robots with parallel kinematics. With the hexapod robot, the gripper platform is guided by three to six linear axes (legs) or articulated arms that work in parallel. (P)

Construction of a hexapod robot

A hexapod robot has a very special shape (hexapod = six-footed), it has six legs. This allows movement in all six directions.

Areas of application

CNC hexapod robot for 5-axis milling
  • in the field of robotics
  • in machine tools, such as when machining complex workpieces
  • in the field of medical technology
  • Hexapod Telescope (HPT), a novel telescope design
  • in motion simulations
  • in casting technology


Due to the high dynamics and the little moving mass, the hexapod robot is suitable for fast workpiece processing. Another advantage is the precise positioning, which is fundamentally better with parallel kinematics. The mobility is also an advantage due to the high degree of freedom. Where machines with serial kinematics meanwhile also have a comparably high degree of freedom.


Relatively large footprint for machine tools with hexapod design. The complex kinematics ensures greater control effort and the low mass makes it more susceptible to vibrations. The high wear and tear and the thermal load on the measuring systems must also be taken into account.


The Fanuc f-200i is one of the few hexapod robots that are built in series.
