Different Robot Varieties

Sep 18, 2013

Robotic tasks keep evolving as technology continues to advance. Automation is providing solutions for precision, speed, and efficiency.


The scope of tasks robots can per­form is expand­ing rapid­ly each year. With­in the past few decades, robots have replaced man­u­al work­ers in many process­es that were haz­ardous, tedious, or tir­ing for humans. Automa­tion can enhance a manufacturer’s pre­ci­sion, speed, and effi­cien­cy com­pared to man­u­al labor.

Indus­tri­al robots are ide­al for repet­i­tive or dan­ger­ous tasks, like lift­ing heavy objects, han­dling chem­i­cals, paint­ing, and per­form­ing assem­bly work. They are found in auto­mo­bile and man­u­fac­tur­ing indus­tries. The first type of indus­tri­al robot is the Cartesian/​Gantry robot. It is equipped with an arm with three joints, coin­ci­dent with a Carte­sian coor­di­na­tor, and is used for pick and place work, sealant appli­ca­tion, machine han­dling, and weld­ing. A cylin­dri­cal robot can han­dle die cast­ing oper­a­tions and oth­er assem­bly oper­a­tions. A spher­i­cal robot spe­cial­izes in weld­ing. SCARA robots are ide­al for pick and place work due to their par­al­lel rotary joints that pro­vide com­pli­ance. Artic­u­lat­ed robots have at least three rotary joints, and are use­ful for spray paint­ing. Par­al­lel robots have arms with con­cur­rent pris­mat­ic or rotary joints. 

Robots are also used in the agri­cul­tur­al sec­tor. Farm­ers dri­ve their trac­tors over their ground repet­i­tive­ly dur­ing the year, and their land becomes gen­tle. Deme­ter, a robot agri­cul­tur­al har­vester, is the epit­o­me of com­mer­cial mobile robot­ic tech­nol­o­gy. This robot con­tains con­trollers, posi­tion­ers, safe­guards, and task soft­ware specif­i­cal­ly designed for the needs of com­mer­cial agriculture. 

The mil­i­tary uses robots to inves­ti­gate dan­ger­ous or haz­ardous envi­ron­ments. The Pio­neer robot is a remote recon­nais­sance sys­tem for struc­tur­al analy­sis of build­ings. A tele­op­er­at­ed mobile robot can deploy sen­sors, a map­per cre­ates real­is­tic 3D mod­els of a build­ing inte­ri­or, and a core­bor­er cuts and retrieves sam­ples of struc­tur­al mate­ri­als. Oth­er envi­ron­men­tal sen­sors are also impor­tant. Anoth­er robot, the Dante II, is also used for haz­ardous ter­rain. It rap­pelled down an Alaskan vol­cano, and walked over the rough ter­rain to deter­mine how much car­bon diox­ide, hydro­gen sul­fide, and sul­fur diox­ide exist in the gas in the crater. The Dante sent back this infor­ma­tion via satel­lite, and saved humans from hav­ing to enter this crater.

Project Jere­my is a col­lab­o­ra­tive project between NASA and San­ta Clara Uni­ver­si­ty: it is a robot­ic under­wa­ter rover used to gath­er infor­ma­tion about marine life. Using robots in freez­ing water like the Arc­tic Ocean enables humans to gain impor­tant infor­ma­tion that might not oth­er­wise be recovered.

Of course, robots are of major impor­tance to the aero­space indus­try. A Remote­ly Oper­at­ed Vehi­cle is an unmanned space­craft that can hov­er in flight, or land and make con­tact with an extrater­res­tri­al body, or it can be a rover that moves over ter­rain after land­ing. The Sojourn­er rover is one of the best-known ROVs. 

As you can see, there are many vari­eties of robots avail­able. Robots​.com is a cer­ti­fied indus­tri­al robot inte­gra­tor that helps com­pa­nies incor­po­rate oper­a­tion into their shopfloors.
