Motion Systems – Hybrid Hexapods and Tripods<br />
Tripods allow a vertical lift and also the tilt around two axes.<br />
Very often they are combined with XY linear stages to create<br />
5-axis systems. With rotary axes on top or at the base we can<br />
even extend them to 6-axes-systems, so called hybrid hexapods.<br />
The fact, that they are only designed with three universal<br />
joints at the upper platform and three solid joints at the<br />
bottom make tripods mechanically order of magnitudes<br />
more precise than most traditional hexapods.<br />
Key Features<br />
• More precise than any hexapod solution<br />
• Larger translation-, tilt- and rotation ranges possible<br />
• Larger loads possible<br />
• More dynamic than hexapod systems<br />
• Vector forward and inverse kinematics<br />
Hexapods are usually designed with six joints at the top and<br />
bottom which inherently is leading to higher tolerances. For<br />
this reason Tripods are in direct competition with hexapods<br />
with many advantages in almost all aspects.<br />
