What is a serial robot?

Many people have seen serial robots in action either on assembly lines or in movies. An example is a robotic arm that helps build a product. It is a serial robot because the arm has joints connected in the series and each joint has one or more engines or drivers connected to the rods that allow the arm to move by what seems to be in the human way.

Human arms is first attached by shoulder joint, then Lok and irrigation. This is also a serial configuration, but it is much more complicated than it is found in most serial robots. The shoulder joint of the person allows a wide range of movement as well as wrists. In robotics, several engines with interconnection of bars must be used that allow a similar type of movement. The "engines" in the arm of man are muscles running throughout the arm and to the fuselage.

When one compares the mercy of a professional dancer with the event of a typical serial robot, the difference become obvious. Serial robot cannot be as charming because it does not have so many possible variationsU and strength in robotic engines. Even with sophisticated dance robots, motor forces are controlled by digital software that brings delay that limits graceful movement.

Serial robots must be graceful enough to perform their task. Usually, the part must be lifted, placed just and in some way treated, such as soldering on the plate on the circuit or tightened by the tool. Performing this task does not necessarily require smooth or graceful movement.

In the early design of serial robots, the human body was emulated to replace employees on the assembly line. Later designs disappeared from this model and considered only what was practical. As the requirements for better accuracy increased, the designs have been improved to the ThNA serial robots can - with the addition of laser cutting technology - to mimic skilled craftsmen. Serial robots can also sculptorCurrent dental crowns.

Universal problems in serial robotics that require constant evaluation include amplification of errors from joint to joint, engine weight or drive, and overall strength and stiffness. The serial robot must be strong enough to perform its tasks hundreds of thousands of times, but not so heavy to slow the operations. This is especially important in a long assembly line. A minor delay can become the main problem in the line.
