Vocabulary

Bio-Inspiration – “Using phenomena in biology to stimulate research in non-biological science and technology” – George M. Whitesides

Gaits – “Gait is the pattern of movement of the limbs of animals, including humans, during locomotion” – Wikipedia

Motors – “Motors are electromagnetic devices that use the interaction of magnetic fields and conductors to convert electrical energy to mechanical energy for rotation.” – SeeedStudio

Degrees of Freedom – “Degrees of freedom are specific, defined modes in which a mechanical device or system can move. The number of degrees of freedom is equal to the total number of independent displacements or aspects of motion.” – TechTarget

Torque – “Torque is a measure of the force that can cause an object to rotate about an axis. Just as force is what causes an object to accelerate in linear kinematics, torque is what causes an object to acquire angular acceleration.” – Khan Academy

MS-LS3-1Complex and microscopic structures and systems can be visualized, modeled, and used to describe how their function depends on the shapes, composition, and relationships among its parts, therefore complex natural structures/systems can be analyzed to determine how they function.
MS-PS2-2Plan an investigation to provide evidence that the change in an object’s motion depends on the sum of the forces on the object and the mass of the object.
HS-LS1-2Develop and use a model based on evidence to illustrate the relationships between systems or between components of a system.
the hierarchical organization of interacting systems that provide specific functions within multicellular organisms.
HS-PS2-1Analyze data to support the claim that Newton’s second law of motion describes the mathematical relationship among the net force on a macroscopic object, its mass, and its acceleration.
