Jun 27, 2016nbsp018332Unique elastomeric rotary actuators based on pneumatically driven peristaltic motion are demonstrated. Using siliconebased wheels, these motors enable a new class of soft locomotion not found in nature, which is capable of withstanding impact, traversing irregular terrain,
Most vane-type rotary actuators operate at lower pressure and torque limits of 2500 to 5000 in. lb. some manufacturers do make units that operate at up to 3000 psi, with torque in excess of 700,000 in. lb. vane-type rotary actuators have no effective way of internally cushioning or limiting the degree of rotation.
For this reason, this paper presents a summary of design considerations for creating erf-based actuators, an erf-based valve design for an erf actuator and a new experimental test-bed to obtain viscosity and yield characteristics of the erf at flow rates as low as 0.049 lmin, an order of magnitude lower than industrial rheometers.
