Rotary Motor

Rotary motors are actuators that use a piece of energy to form an oscillatory motion at a certain angle of movement. Rotary actuators can have up to a rotation of 360 degrees. This allows it to differ from a linear motor as the linear is bound to a set distance compared to the rotary motor. Rotary motors have the ability to be set at any given degree in a field making the device easier to set up still with durability and a set torque.

Rotary motors can be powered by 3 different techniques such as Electric, Fluid, or Manual. However, Fluid powered rotary actuators have 5 sub-sections of actuators such as Scotch Yoke, Vane, Rack-and-Pinion, Helical, and Electrohydraulic. All forms have their own specific design and use allowing the ability to choose multiple angles of degree.

Applications for the rotary actuators are just about endless but, will more than likely be found dealing with mostly hydraulic pressured devices and industries. Rotary actuators are even used in the robotics field when seeing robotic arms in industry lines. Anything you see that deals with motion control systems to perform a task in technology is a good chance to be a rotary actuator.

Soft Actuators

A soft actuator is one that changes its shape in response to stimuli including mechanical, thermal, magnetic, and electrical. Soft actuators mainly deal with the robotics of humans rather than industry which is what most of the actuators are used for. For most actuators they are mechanically durable yet do not have an ability to adapt compared to soft actuators. The soft actuators apply to mainly safety and healthcare for humans which is why they are able to adapt to environments by disassembling their parts. This is why the driven energy behind soft actuators deal with flexible materials like certain polymers and liquids that are harmless to humans.
