Morphogenesis02:19

Morphogenesis

28.3K
Plant morphogenesis—the development of a plant’s form and structure—involves several overlapping developmental processes, including growth and cell differentiation. Precursor cells differentiate into specific cell types, which are organized into the tissues and organ systems that make up the functional plant.

Microbial Morphologies

35
Bacterial and archaeal cells exhibit remarkable diversity in shape and structure, critical in their adaptability and functionality. Among bacteria, the most commonly observed shapes include cocci and bacilli. Cocci are spherical and may exist singly or in groupings such as pairs (diplococci), chains (streptococci), clusters (staphylococci), or tetrads. Bacilli, in contrast, are rod-shaped and can also occur as single cells, in pairs, or chains, depending on their environmental and genetic...

Plastic Deformations01:14

Plastic Deformations

101
It is essential to understand how structural members behave under plastic deformation when the bending stress exceeds the material's yield strength. This state of deformation permanently alters the shape of the member, in contrast to the linear elastic behavior observed before yielding. The strain at any point in the member is expressed in terms of maximum strain. Notably, the neutral axis, which coincides with the centroid during elastic bending, shifts away from the centroid under plastic...

Plastic Deformations of Members with a Single Plane of Symmetry01:21

Plastic Deformations of Members with a Single Plane of Symmetry

103
When a structural member undergoes plastic deformation due to bending, it is crucial to understand the position of the neutral axis and the stress distribution. This member, characterized by a single plane of symmetry, exhibits a uniform stress distribution, with negative stress above the neutral axis and positive stress below. Notably, the neutral axis does not align with the centroid of the cross-section. This misalignment is typical in cases where the cross-section is not rectangular or...

Plastic Deformation in Circular Shafts01:20

Plastic Deformation in Circular Shafts

201
When materials are subjected to forces that surpass their yield strength, they undergo a process known as plastic deformation. This results in a permanent alteration or strain in their structure. This concept can be specifically applied to circular shafts, where the deformation leads to a change in its shape. The precise evaluation of this plastic deformation requires understanding the stress distribution within the circular shaft, which is achieved by calculating the maximum shearing stress in...

  • Design and fabrication of three distinct morphing robotic systems: adaptive grippers, a quadrupedal robot, and an untethered amphibious robot.
  • Creation of a library of embedded morphing modules for programmable shape transformations.

Main Results:

  • Successfully demonstrated self-sensing shape-morphing grippers capable of adaptive grasping.
  • Showcased a quadrupedal robot that can alter its body shape for diverse terrestrial locomotion (walking, crawling, climbing).
  • Presented an untethered robot capable of morphing its limbs for amphibious locomotion, alongside a module library for versatile programmable shapes.

Conclusions:

  • The embedded shape-morphing scheme enables robots to reconfigure their morphology autonomously.
