Solution:

Workspace fixtures are accessories and add-on of a robot. These fixtures form a part of a robot to perform a particular task. Work space fixtures used in the work space of the robot are:

(1) Part feeders

(2) Transport devices

(3) Part-holding devices

1.) Part feeders :

For the object to be successfully grasped by the robot, the part must be presented to the robot in the manner compatible with the tool configurations realizable by the manipulator.

Part feeders are usually arranged concentrically around the robot base near the outer boundary of the work envelope.

Part feeders are activated electromechanically and electrically.

Part feeders activated electrically are basically vibratory-bowl devices and those that are activated electromechanically are gravity fed part feeders.

2.) Transport devices:

Devices which are used to move parts from one robotic work cell to another work cell.

Conveyors and Carousels are examples of transporting devices.

Conveyers and carousels are special part feeders. They transport parts between robots and from one robotic work cell to another linearly.

The conveyor belt transports the parts horizontally either from left to right or from right to left but in one direction only.

It consists of a rotating table with a central pedestal.

3.) Part-holding devices:

Devices which are used to hold a sub-part in exact position and orientation. It is mainly used in assembly line task.

Most robots are one-handed and have only one tool in operation at any given time.

A work-holding fixture is considered as a fixed tool. It is fixed and immobile. It cannot move or reorient itself. Examples: jigs, clamps etc.
