Introduction
PARALLEL MANIPULATORS
As the name indicates, in this case the motors and members are mounted in parallel from a base to a common platform. Research on parallel manipulators began in the 1970s and their popularity is rapidly increasing.
The main advantages of parallel architectures are the following:
The structural stiffness (which greatly increases the payload to mass ratio of the robot);
The dynamic properties;
The possibility of mounting the actuators on or close to the base of the robot.
DELTA ROBOT
A Delta robot is a type of parallel robot. It 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 effecter. The delta robots have popular usage in picking and packaging in factories because they can be quite fast.
It was invented in the early 1980s by the research team led by Professor Reymond Clavel at the École Polytechnique Fédérale de Lausanne (EPFL, Switzerland). The purpose of this new type of robot was to manipulate light and small objects at a very high speed.
CONVEYOR SYSTEM & ROLLER
Conveyor systems allow quick and efficient transportation for a wide variety of materials, which make them very popular in the material handling and packaging industries.
Roller is support at the end of conveyor system for the movement of belt over it. Some properties of these rollers include proper friction in order to avoid slippage, proper diameter to reduce load on motor connected to it. We selected 25 mm diameter Aluminium rod and machined it as per the given Model .
DELTA ROBOT SPECIFICATIONS
LOWER ARM
The lower arm of Delta Robot is connected to Upper arm or the Hip through universal joints and support shaft. The lower arm is a rod of required diameter and length and of lighter material in order to reduce total weight on Motor. The rod is threaded at the end to insert it in the bearing.
Material = Aluminium
Diameter = 8 mm
