In simple terms, a gimbal is a pivoting platform that allows an object to rotate around one or more axes. They’re often found in photography and videography applications to stabilize cameras, as well as in navigation systems for ships. In these applications, two or more gimbals are mounted together with orthogonal axes (axes mounted 90 […]
What are hexapod robots (also referred to as Stewart platforms)?
Multi-axis systems can be designed and built with either serial kinematics or parallel kinematics. In systems built on the principle of serial kinematics, one axis sits on top of another axis, and each axis is driven individually, independent of the others. Cartesian robots are a good example of serial kinematic design. In parallel kinematic systems, multiple axes […]
What is a Cartesian robot?
We’ve written several articles on this site about Cartesian robots, but let’s take a step back and define exactly what makes a robot a Cartesian robot, as opposed to another type of robot or multi-axis system. First, a Cartesian system is one that moves in three, orthogonal axes — X, Y, and Z — according to […]
Low-profile linear stepper motor stage from H2W Technologies
The LSS-016-04-006-01A-ME is one of a revolutionary new series of low-profile linear stepper motor positioning stages that integrates an absolute linear encoder and a single-axis linear stepper motor stage. This enables the linear stepper motor stage to operate as a 2-phase brushless linear motor when coupled with motion control electronics provided by H2W Technologies (H2W). […]
Large area travel X-Y stages from IntelLiDrives
Large area travel X-Y stages from IntelLiDrives offer precise fine positioning and control achieved through the combination of a stable closed-loop control system and an associated joystick option. In addition, the stages can be combined with the company’s Z stages to form an XYZ stage ideally suited for laser scanning microscopy. The travel range is […]
What are goniometer stages and where are they used?
The term “goniometer” can refer to a type of device that measures angles or to a device that rotates objects to a precise angular position. The former type, for measuring angles, is widely used in physical therapy to measure the range of motion of joints, such as the wrist or knee. This type of goniometer […]
What’s the difference between serial kinematics and parallel kinematics in multi-axis motion design?
Today’s positioning tables and stages include hardware and software that’s more customized than ever to satisfy specific output requirements. That’s made for motion designs that move accurately through even complicated multi-axis commands. Precision feedback is key to such functionality — often taking the form of optical or (electronics-augmented) magnetic encoders for nanometer-scale resolution and repeatability […]
LINAK linear actuators in medical sit-to-stand lifts facilitate rehabilitation
By 2050 there will be two billion people older than 60, according to the WHO … and 2035 will see a 12.9 million shortage of healthcare professionals. Fortunately, some new linear-motion technologies could help satisfy some of the growing need for healthcare, especially in the segment of the industry dedicated to patient rehabilitation. Consider one […]
Three-axis gimbal mount from OES features high resolution and stability
The new AU300-AER three-axis gimbal mount from OES (Optimal Engineering Systems, Inc.) features full 360˚ rotation of each axis. This three-axis gimbal mount handles loads to 10 kg (22.5 lb) and has a clearance of 300 x 300 mm, (11.8 in. x 11.8 in.) around the roll axis stage. The azimuth stage rotary table is […]
Linear motion designs see wider adoption of linear direct drives
Direct drives are a motion-control technology projected to see high rates of adoption in coming years, according to market research by the ARC Advisory Group. That’s due in part to an array of industries driving for higher throughput and more accurate processes. According to Brian Scott, applications engineer at Nippon Pulse America Inc., linear shaft […]
