The review is performed by using well-defined performance criteria with a direction to identify the exemplary and potential applications. In addition to this, initial guidelines to compare the performance and applicability of these novel actuators are provided. The meta-analysis is restricted to five main types of actuators: shape memory alloys (SMAs), fluidic elastomer actuators (FEAs), shape morphing polymers (SMPs), dielectric electro-activated polymers (DEAPs), and magnetic/electro-magnetic actuators (E/MAs). In exploring and comparing the capabilities of these actuators, the focus was on eight different aspects: compliance, topology-geometry, scalability-complexity, energy efficiency, operation range, modality, controllability, and technological readiness level (TRL). The overview presented here provides a state-of-the-art summary of the advancements and can help researchers to select the most convenient soft actuators using the comprehensive comparison of the suggested quantitative and qualitative criteria. Keywords: soft-robotics; actuator performance; SMA; SMP; FEA; DEAP; E/MA 1.

    Comparing Traditional and Integrated Rod-Style Linear Actuators

    How roller-screw and ball-screw actuators compare in high-force applications: As electric rod-style actuators overtake fluid power in a variety of high-force applications, it is important to understand how different screw technologies compare in the search for optimum performance and low life-cycle cost. Electric rod-style screw actuators are replacing fluid power in high-force applications throughout industry. Tasks once limited to hydraulic and pneumatic cylinders such as pressing, holding, lifting and spot welding are now being performed by electric actuators that offer lower life-cycle costs. Hydraulic and pneumatic cylinders still have their place, but electric actuators have numerous performance advantages in high-force applications up to and exceeding 50,000 lbf. Some of these advantages include a smaller footprint; a long and more predictable life; lower life-cycle costs; greater accuracy, control and flexibility; lower maintenance; faster change-over and setup; lower energy use; and less environmental impact. In general, screw mechanisms provide the means to produce linear motion by the rotation of either the screw or nut in an assembly. The screw is a cylindrical element that has threads; the nut is a matching component that rides on the screw. Each component is capable of rotating independently upon the other. Linear motion occurs by restraining one element. Tolomatic is a leading supplier of electric linear actuators. Tolomatic’s In high-force applications, two types of screw technologies are typically used in electric 60+ years of expertise covers a wide rod-style actuators: ball screws and roller screws. Actuators with ball screws and roller range of industries and linear motion screws are now able to achieve extremely high forces, making them suitable for many applications.

However, there’s not much information comparing dierent types of actuators in real-world settings. So, how do you choose the best type of actuator for your application? Should you use a belt or a lead screw? A rack and pinion or a ball screw? A fixed or moving motor? If you’re building your own actuator, which types are the easiest to manufacture? Which systems are the most (and least) robust? Every day, Teknic’s servo systems power hundreds of thousands of actuators. We don’t build actuators, but, for our customers to be successful, their actuators must perform well and reliably. For the past thirty years, Teknic has worked alongside our OEM customers, helping them select and design mechanical systems to optimize their machines’ motion performance. We’ve learned quite a bit over the years and we’d like to share that knowledge with the general public. General Comparisons Between Actuator Types If all machines had the same motion requirements, there’d be one type of actuator—but there are many dierent machines with various requirements.

The open architecture rotating screw and rotating nut motorized lead screws suit applications where external guidance is present or a high level of design flexibility is required, while the closed assembly of the motorized lead screw actuator is ideal to further simplify the design process and remove requirements for external guidance. Technology Overview Rotating screw assemblies actuate by having the motor rotate a lead screw and translate a load that is attached to the lead nut. Rotating nut assemblies actuate by rotating a nut within the motor body. Motion is achieved by constraining the motor and translating a load attached to the lead screw or constraining the lead screw and translating a load attached to the motor. Rotating Screw Configuration MLS The rotating screw design, which is ideal for rapid prototyping, features our patented Taper-Lock design to connect the lead screw to the motor shaft. It is best suited for applications where high levels of maintenance are anticipated, frequent disassembly/reassembly is required, or easy removal of the lead screw is necessary. Customers also can consider field serviceability for this configuration. Rotating Nut Configuration MLN The rotating nut design features our patented integration of a lead nut into the motor rotor to maximize screw diameter, which increases load capacity. It is ideally suited for applications where no visible rotation is desired or where it is necessary to translate a load on either side of the motor.

There are various parameters to consider when selecting a Rotary Stepper Motor or a Stepper Linear Actuator for a particular motion control application. The following lists many key items to consider: • Speed range required • Desired rotary or linear step resolution and step accuracy • Maximum loading in each direction • Type of load (frictional, inertial, mechanical spring, shock load, or combinations of these) • Orientation of the motor’s rotary or linear axis • Mechanical alignment • Type of drive that will be used (typically a Chopper Drive or an L/R Drive) • Desired step mode (full, half, quarter, eighth, etc.) • The use of acceleration and/or deceleration ramping • Duty cycle: the operational on (energized) time relative to any off (or reduced power) time • Levels of Operating Current and Hold Current relative to the rated current • Maximum voltage / current capabilities of the Drive • Applied power supply voltage (relative to the rated voltage of the motor) • Environmental conditions Suppliers of Rotary Stepper Motors provide speed versus torque performance curves of their various motors, while suppliers of Stepper Linear Actuators provide speed versus force performance curves of their various actuators, in addition to the characteristics and mechanical dimensional specifications.
