Linear Actuators vs Rotary Actuators: The Core Choice for Humanoid Robot Joints
The robot joint module is the core hardware of humanoid robots, currently mainly divided into two major categories: rotary and linear. In humanoid robot designs, the choice often involves trade-offs based on the application scenario and manufacturing cost.
Rugged electric actuators provide reliable steering for extensible, self-driving platform
Whether OxDrive's next application is in agritech, construction, forestry, warehouse logistics or any other untapped use, chances are good that it will need a reliable actuator. And when it does, Horton will likely continue specifying Thomson linear motion solutions.
Joint actuators: The fundamental component for humanoid robots' power and dexterity
Although there are structural similarities between humanoid robot joints and collaborative robot joints, there are still many differentiated requirements that pose higher performance demands.
Actuator Technology in Robotics Applications
LINAK offers easy integration with robotics applications through CANOpen. Our DC actuators match up with battery voltage to provide the complete linear motion system.
What Are the Differences Between Linear and Rotary Actuators?
Depending on the nature of the output motion, actuators can be divided into linear and rotary. Each of these is available in different versions and configurations that help deliver the desired outcome.
10 Different Options For Controlling Linear Actuators
Below you will find ten different options for controlling linear actuators. This list is intended to give you an overview of what's possible for linear actuator control. It's not exhaustive, there are other options, but these are the ones that will work for most people.
Acting Like a Muscle, Nano-Sized Device Lifts 165 Times its Own Weight
Rutgers University-New Brunswick engineers have discovered a simple, economical way to make a nano-sized device that can match the friendly neighborhood Avenger, on a much smaller scale. Their creation weighs 1.6 milligrams (about as much as five poppy seeds) and can lift 265 milligrams (the weight of about 825 poppy seeds) hundreds of times in a row.
Artificial muscle for soft robotics: Low voltage, high hopes
Phys.org: Soft robots do a lot of things well but they're not exactly known for their speed. The artificial muscles that move soft robots, called actuators, tend to rely on hydraulics or pneumatics, which are slow to respond and difficult to store.
Dielectric elastomers, soft materials that have good insulating properties, could offer an alternative to pneumatic actuators but they currently require complex and inefficient circuitry to deliver high voltage as well as rigid components to maintain their form—both of which defeat the purpose of a soft robot.
Now, researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a dielectric elastomer with a broad range of motion that requires relatively low voltage and no rigid components. They published their work recently in Advanced Materials. Cont'd...

3D Vision: Ensenso B now also available as a mono version!
This compact 3D camera series combines a very short working distance, a large field of view and a high depth of field - perfect for bin picking applications. With its ability to capture multiple objects over a large area, it can help robots empty containers more efficiently. Now available from IDS Imaging Development Systems. In the color version of the Ensenso B, the stereo system is equipped with two RGB image sensors. This saves additional sensors and reduces installation space and hardware costs. Now, you can also choose your model to be equipped with two 5 MP mono sensors, achieving impressively high spatial precision. With enhanced sharpness and accuracy, you can tackle applications where absolute precision is essential. The great strength of the Ensenso B lies in the very precise detection of objects at close range. It offers a wide field of view and an impressively high depth of field. This means that the area in which an object is in focus is unusually large. At a distance of 30 centimetres between the camera and the object, the Z-accuracy is approx. 0.1 millimetres. The maximum working distance is 2 meters. This 3D camera series complies with protection class IP65/67 and is ideal for use in industrial environments.
