Abstract Additive manufacturing has many advantages in creating highly complex customized structures. In this study, a low‐cost multiscale stereolithography technology that can print macroscale object with microscale surface structures high throughput is demonstrated. The developed realized by dynamic switching of laser spot size and adaptively sliced layer thickness. An optical filter based on subwavelength resonance grating used to modify for lasers different wavelengths achieves maximum...
Existing platforms for underwater exploration and inspection are often limited to traversing open water must expend large amounts of energy maintain a position in flow long periods time. Many benthic animals overcome these limitations using legged locomotion have different hydrodynamic profiles dictated by body morphologies. This work presents an robot with soft legs inflatable morphing that can change shape influence its characteristics. Flow over the separates behind trailing edge inflated...
Intertidal sea stars often function in environments with extreme hydrodynamic loads that can compromise their ability to remain attached surfaces. While behavioral responses such as burrowing into sand or sheltering rock crevices help minimize loads, previous work shows also alter body shape response flow conditions. This morphological plasticity suggests star may play an important role. In this study, we measured the fluid forces acting on surface-mounted and spherical dome models water...
This paper presents a novel omnidirectional gait design and feedback control of radially symmetric tripedal friction-driven robot. The robot features 3 servo motors mounted on 3-D printed chassis 7 cm from the center mass separated 120 degrees. These drive limbs, which impart frictional reactive forces body. We first introduce mathematical model for motion, then show experimental observations performed uniform friction surface, validated accuracy model. was used to create an that allows...
Two light beams with different colors indicate there are two lasers of wavelengths in the 3D printer to improve printing efficiency, as presented article number 1800638 by Wei Wu and co-workers. The denticle array being printed is structure this work was inspired shark skin texture fluid drag reduction function.
Abstract This study seeks to provide physical insight into the friction-driven crawling locomotion of systems with radially symmetric bodies. Laboratory experiments a tripedal robot show that both translation and rotation can be achieved just three independently actuated rigid limbs, i.e., 3 degrees-of-freedom. These observations are rationalized using simple mathematical model, which assumes friction at each limb is linearly proportional normal force contact point, opposes direction motion....
In our work, the new stereolithography technology has been used to construct 3D shark skin teeth with both high resolution and throughput. this way complex structures more closely mimicking real textures have fabricated (Figure 3-4). Cylinder pipe (at same size) without interior were printed study effects of texture in flow. The pressure gradient across section are measured by existing wet-wet differential transducers. Then drop measurement can be translated into a friction coefficient using...
This letter considers control of a radially symmetric tripedal friction-driven robot. The robot features 3 servo motors mounted on 3-D printed chassis 7 cm from the center mass and separated 120 degrees. These drive limbs, which impart frictional reactive forces body. Experimental observations performed uniform friction surface validated mathematical model for motion. was used to create gait map, instantaneous omni-directional control. We demonstrated line following using live feedback an...
