M-20i A Series Basic Description The evolutionary design of the M-20iA solves two of the oldest problems for industrial robots. The first issue is the time it takes to engineer the robot dressout and the second is the down-time caused when the dressout is disrupted by contact with plant equipment. The innovative M-20iA solves these issues with a hollow upper arm and wrist. This unique design permits the utilities to be neatly contained within the arm, eliminating dress out issues like snagging, tearing and rubbing. A shelf with ample space on the back of the upper arm completes the package by allowing peripheral equipment to be easily mounted. The hollow arm and wrist together with the shelf greatly simplifies the integration engineers job. To complement the built-in vision, the M-20iA has an integrated vision cable from the J1 base to J3 interface panel. This makes the addition of vision to the robot application much easier. This design is also a great benefit for offline simulations because the dress out and control boxes can all be designed to fit with in the confined space of the robot arm and eliminates the guess work of dress out interference. This exceptional design comes with out sacrificing any of the robot’s performance specifications. In fact this robot is an industry leader in payload, reach and axes speed. Add this to the industry leader in reliability and this robot is the perfect solution for your robotic application.

M-20iA™ SeriesBasic Description

The evolutionary design of theM-20iA solves two of the oldestproblems for industrial robots. Thefirst issue is the time it takes toengineer the robot dressout and thesecond is the down-time causedwhen the dressout is disrupted bycontact with plant equipment. Theinnovative M-20iA solves theseissues with a hollow upper arm andwrist. This unique design permitsthe utilities to be neatly containedwithin the arm, eliminating dressout issues like snagging, tearingand rubbing. A shelf with amplespace on the back of the upper armcompletes the package by allowingperipheral equipment to be easilymounted. The hollow arm and wristtogether with the shelf greatlysimplifies the integration engineersjob.

To complement the built-in vision,the M-20iA has an integratedvision cable from the J1 base toJ3 interface panel. This makesthe addition of vision to the robotapplication much easier.

This design is also a great benefitfor offline simulations because thedress out and control boxes canall be designed to fit with in theconfined space of the robot armand eliminates the guess work ofdress out interference.

This exceptional design comes without sacrificing any of the robot’sperformance specifications. In factthis robot is an industry leader inpayload, reach and axes speed.Add this to the industry leaderin reliability and this robot is theperfect solution for your roboticapplication.
