What is a Delta parallel robot?
A Delta robot is a type of parallel robot that consists of three arms connected to universal joints at the base. The key design feature is the use of parallelograms in the arms, which maintains the orientation of the end effector, by contrast to Stewart platform that can change the orientation of its end effector.
What is a parallel manipulator used for?
A parallel manipulator is a mechanical system that uses several computer-controlled serial chains to support a single platform, or end-effector. Perhaps, the best known parallel manipulator is formed from six linear actuators that support a movable base for devices such as flight simulators.
How do delta robots work?
Delta robots are robots with a base connected to jointed parallelograms. These parallelograms perform motions in a solitary End of Arm Tooling (EOAT), within a workspace that is dome-shaped. This type of robot is well-known in the industrial field for its ability to execute minute, precise motions.
How are Delta robots programmed?
For delta robot control and trajectory programming was developed software. The program allows the simulation, the workspace analysis, the positions programming and the communication management. The structural design and simulation has been developed using system CATIA.
What is DOF of a robot?
Degrees of freedom, in a mechanics context, 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. The term is widely used to define the motion capabilities of robots.
How do sphere robots work?
The most common drive mechanisms of the spherical robots operate by changing the robot’s center of mass. Other driving mechanisms make use of: (1) conservation of angular velocity by flywheels, (2) environment’s wind, (3) distorting the spherical shell, and (4) gyroscopic effect.
