Rollon and Skyward Experimental Rocketry, a student association at Politecnico di Milano, marked four years of collaboration. Rollon is providing technical support and motion solutions for the team’s Orion rocket, which will be launched at the 2025 European Rocketry Challenge (EuRoC), a university-level rocketry competition in Europe. Orion, the successor to last year’s Lyra, is […]
Motion Casebook
Motion designs key to vertical farming
In a recent case study, we detailed how cable-systems manufacturer HELUKABEL helped automate a vertical-farming installation: Cables satisfy the unique demands of vertical farming. In contrast with approaches to optimize the traditional farming of fields, automated greenhouses solutions eliminate issues associated with tight labor markets, guarding delicate or valuable crops, and the need to apply […]
SMAC actuators satisfy existing OEM form-fit-function requirements
SMAC now sells voice coil actuators that include differential features to satisfy OEM requirements … actuators that allow drop-in replacement of existing motion technologies having the same form, fit, and function. This design process is called MCA Inside and has been key in helping OEMs with an install base or an existing design to solve […]
igus linear guides help drones repel pests
One Spanish OEM has developed a drone for pest control; the design features low-weight carbon linear guides and a micro energy chain and pillow block bearings manufactured by igus. The FitoStinger was developed by the Technology & Advances Centre of Barcelona. It includes an extendable arm that allows the precise spraying of pesticides. Light maintenance-free […]
Linear-actuator application example: New angle on wheelchair vehicle accessibility
Kneeling systems have become widespread on custom wheelchair-accessible vehicles from BraunAbility and other accessible-vehicle converters. Here linear actuators lower vehicles’ rear suspension to reduce the incline angle of wheelchair ramps for easier access. Because the actuators typically mount under the vehicle chassis, they must be rugged. “Our vehicles typically kneel 2.5 to 3 in. We […]
AS/RS design to run new manufacturing and distribution center by 2019
Cimcorp North America of Murata Machinery (Muratec) will supply an installation for end-to-end material handling to Giti Tire at a new South Carolina manufacturing facility. Scheduled for completion in 2019, the turnkey Cimcorp system is called a Dream Factory and will include all the facility’s automation equipment and system control, project management, and integration. Using […]
Video: Electric H-Track actuators from Altra Industrial Motion: Hydraulics drive medical, mobile, and solar designs
In a recent video with Paul J. Heney, I got the chance to review the features of an H-Track actuator from Warner Linear of Altra Industrial Motion. As we detail, applications abound for medical, off-highway, and industrial applications. In fact, the electric H-Track actuators deliver the smooth motion and strength of hydraulics but from a compact […]
LINAK linear actuators let one manufacturer help another make ergonomic assembly tables
Recently, Schneider Electric in the Netherlands consulted the Dutch ergonomics company Krikke de Wit Technische Tiloplossingen to lessen the physical burden of employees on their production line. Workers handling server racks and steel computer patch cabinets needed adjustable and tilting assembly tables to boost production and stay safe from overburdening and injury. Schneider Electric assembles […]
Motion system applications: Better ballscrews, more applications
Ballscrews suit applications needing light, smooth motion, applications requiring precise positioning, and when heavy loads must be moved. Examples include machine tools, assembly devices, X-Y motion and robotics. Factors such as lead accuracy, axial play and preload, and life-to-load relationship are most commonly used to classify ballscrews. Lead accuracy is the degree to which the shaft’s […]
Leadscrews: Motion system mainstays
Among the methods available for converting rotary motion to linear, leadscrews are a mainstay. A leadscrew, or power screw, is a threaded rod or bar that translates rotational motion into linear motion. Leadscrews generate sliding rather than rolling friction between a nut and the screw. Consequently, higher friction means a lower overall efficiency. And efficiency, […]
