Gallery: Hexapod robots – design variations and applications
Hexapod robots, also referred to as simply “hexapods” or “Stewart platforms,” are a type of parallel kinematic device with six degrees of freedom. You might recognize hexapod robots as the technology behind motion simulators and vibration isolation mechanisms, where their six degrees of freedom (X, Y, Z, roll, pitch, and yaw) allow them to accurately […]
Motion Trends: Linear bearings help some CNC machine builders trim cost
Axes on CNC machines to allow spindle movements are mission critical — requiring high accuracy. But doors and other linear axes have different design requirements — with forgiveness and ruggedness being priority instead. Now, linear bearings from Rollon Corp. help some CNC machine builders trim cost and improve reliability by satisfying these unique design requirements. […]
Linear motion trends in slides: Robotics and mobile designs lead the charge
Demand for simple-to-install and pre-integrated linear-slide systems continues unabated … especially in applications only recently automated. Here’s the perspective of Matt Mowry, North American market manager for drylin products at igus: “We’ve supplied fully assembled and customized linear-slide tables … complete with motors and accessories. We’ve also supplied custom-extruded linear profiles and bearing liners to […]
How to measure synchronous (toothed) belt tension
One of the benefits of synchronous belts is their ability to operate with lower tension than their V-belt counterparts. And once the proper tension is determined and applied, synchronous belts rarely need re-tensioning. But improper tension in a synchronous belt drive system — either too low or too high — can lead to poor meshing […]
Festo at Automate 2019: OEM productivity-boosting solutions
Festo is showing electric and pneumatic motion-automation solutions at Automate 2019 April 8 to 11 at McCormick Place in Chicago — Booth 8151. Productivity-enhancing solutions include company-wide component interoperability and online tools for designing subassemblies that slash OEM engineering overhead and reduce delivery time. With the Festo Handling Guide Online, engineers can design single-axis or […]
Linear motor stage offers long travel, nanometer resolution
The new V-417.336025E1 long travel linear motor stage from PI (Physik Instrumente) features travel length of 32 in. (813 mm). The direct-drive stage achieves high velocities to 79 in./sec (2 m/sec) based on a direct drive ironless linear servo motor. High accuracy, repeatability, and functionality are guaranteed by an integrated absolute-measuring linear position encoder featuring […]
When do synchronous belts need flanged pulleys?
Synchronous belts transmit power via positive engagement between profiled teeth on the belt and pulley. Although this tooth engagement (along with proper belt tension) prevents the belt from ratcheting, the belt is free to track, or move side-to-side, on the pulley. To prevent the belt from riding off the pulley, and to resist the lateral […]
Update on roller-screw actuator design and applications (with video and image galleries)
Roller screws are also called planetary roller screws or sometimes satellite roller screws for how their nut-encased rollers orbit the drive-shaft axis during operation. These mechanical rotary-to-linear devices work in an increasing number of electromechanical actuators. Satellite roller-screw geometry includes far more internal contact between load-bearing subcomponents than their ballscrew cousins, and that boosts rigidity […]
Cannabis cultivation leverages modular automation stations
By Michael G. Giunta • National sales manager | Macron Dynamics Uninitiated laymen might assume today’s cannabis is grown through traditional farming — over horizontal outdoor spaces in natural environments managed by Mother Nature. But large-scale cannabis farming is typically indoors and highly automated. That’s for a couple reasons: • Security is a major concern […]
