A parallel kinematic machine benefits from actuators operating simultaneously, sharing loads and reducing accuracy errors and flexibility propagation across the structure.
The end-effector is attached to the base through a series of thin rods to form a tripod in the Cognibotics PKM system. In comparison to a solid beam of equal extent and weight, such a construction is substantially stronger.
This construction is statically determinate, which creates opportunities for relatively simple installation and assembly of the machine without the need for laborious alignment processes when combined with Cognibotics calibration and motion control.
A machine with a unique capacity for accuracy, forces, and stiffness over large working areas is produced by utilising such strengths.
A subfield of mechanics known as parallel kinematics focuses on manipulators made of closed kinematic chains, or devices with several limbs connecting the end effector to the fixed frame.
Such a kinematic structure offers certain benefits in terms of stiffness, acceleration, and weight, but also some disadvantages because of the mechanical complexity and the space constraints.
Such mechanisms have been used in a number of machine tool applications in the machining industry. Hexapod-based earlier designs fell short of expectations, but new topologies show promise.
The primary benefits of parallel kinematic machines are their straightforward designs and shared components. Their limitations in terms of orientation angles, non-linear force transmission and stiffness, a poor operating envelope to machine size ratio, and average precision are some of their intrinsic drawbacks.
The Global Parallel Kinematic Machine market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
The Cognibotic SigmaTau is a ground-breaking parallel kinematic motion (PKM) robot that has the potential to replace many current robot structures in upcoming industrial automation applications. The SignaTau is an example of a new breed of lightweight robots that have been designed for precision processing over very large workspace volumes.
The rigidity and robust geometry of the robot structure enable it to handle large process forces with remarkable accuracy. The structure may definitely be envisioned having applications in coordinate measurement and 3D scanning for industrial metrology.
When working on large precision components with extra-tight tolerances when typical robot accuracy is insufficient and workpieces are 3 metres or greater, robot cells can be built as extremely effective solutions.
The SMARPOD ensures great resolution and repeatability while providing the same degrees of freedom as traditional hexapod systems. SMARPODs show greater stiffness and rigidity compared to serial kinematic systems with six degrees of freedom. A simple software package ensures quick setup and easy integration into your own control environment.
Like all other SmarAct products, SMARPODs may be combined into entirely unique settings and are highly customizable.
By offering the ideal mix of performance and price, SigmaTau is bridging the gap between CNC machine tools and industrial robots. Tolerances down to 0.05mm can be achieved over huge volumes.
A SigmaTau PKM robot can be modified to perform a variety of tasks demanding high accuracy and high process force over huge work areas, including friction stir welding, laser welding, drilling, riveting, milling, and inspection.
