What is spatial kinematics?

Spatial kinematics is used to describe the movement of the object in three -dimensional space. Examples of spatial kinematics are bending the knee on the joint or move the robotic arm.

Imagine bending your arm. How would you measure the distance of its movement? Would you measure from the tip of your fingers or elbow? When the arms bend, its parts move down, its parts move up. What direction does it move? Different parts of the arm move at different speeds. How can you measure how fast it moves?

Unlike basic kinematics, which studies the movement of objects along direct lines, spatial kinematics is more complicated. In basic kinematics you only need two fixed points, start and finish, to describe movement. For example, the car drives a flat road between two cities. With these two points, you can measure its speed, speed, travel duration and travel distance. In spatial kinematics, the movement of the building must be measured from the Asia points along a variety of movement.

using more than isScientists and engineers can divide the bottom of the fixed point on a three -dimensional movement on the single -dimensional movements. These measurements are then involved in patterns that allow them to scientifically describe how the object moves.

Spatial kinematics is very important in robotics. In order to program a robot that extends his arm and catches something, many complex formulas enter the game. The movement of the robotic arm does not occur on one line. Many mechanisms must develop a specific amount of force in a specific direction in order to get the arms to a certain distance from the robot.

Doctors also use spatial kinematics to study people with prosthetic limbs. In one study, in the Walter Reed Army medical center, the patient was covered by emitting a tutorial and filmed with a special camera when they walked with a prosthetic foot. Images were fed to the computer and the diodes were used to create a modelthe patient's movement. Each diode could represent a fixed point and allow doctors to measure objectively as the patient moved with the prosthesis.
