Speed vs Flexibility: 4-axis vs 6-axis robots

Aug 9, 2013

Industrial robots provide a wide range of benefits on your production line. However, it is important to understand your needs and select the perfect one. If you are looking for increased speeds, especially on your assembly line, then a 4-axis robot is the way to go. The six-axis robots have the edge when it comes to dexterity and flexibility.


There are sev­er­al mod­els in indus­tri­al robot­ics. Some are faster, while oth­ers are more flex­i­ble and able to oper­ate many dif­fer­ent appli­ca­tions. When choos­ing, cus­tomers have to con­sid­er the four-axis vs. the six-axis robot, or speed vs. flexibility.

What is a four-axis robot?

If assem­bly is your game, and you want fast, the SCARA four-axis robot may be the way to go. In the fight of 4‑axis ver­sus 6‑axis robots, the four-axis SCARA is the faster mod­el. They are very com­mon in assem­bly, pick and place, and pack­ag­ing appli­ca­tions. This four-axis robot is easy to use and can be bolt­ed to a table, pro­grammed, and then ready to work.

What are six-axis robots?

Six-axis, artic­u­lat­ed robots, as opposed to four-axis robots, have the edge when it comes to dex­ter­i­ty and flex­i­bil­i­ty. They allow for greater flex­i­bil­i­ty and can per­form a wide vari­ety of appli­ca­tions, such as mate­r­i­al han­dling, pick­ing, stack­ing, assem­bly, and pack­ag­ing. Four-axis robots can­not manip­u­late a part with the same free­dom that a six-axis robot does. Plus, SCARA four-axis mod­els are usu­al­ly small­er and have a lim­it­ed range, unlike the six-axis robots that can be large or small.

Along with their dex­ter­i­ty, six-axis robots edge out the com­pe­ti­tion in the four-axis ver­sus six-axis by being eas­i­er to pro­gram. The robot is more flex­i­ble and can han­dle the con­stant changes in prod­uct design and process.

What type of robot is the best?

In the great 4‑axis vs. 6‑axis robot­ics debate, it has always been known that 4‑axis robots have an edge as far as high­er speed and pre­ci­sion, as well as a low­er cost for the unit. How­ev­er, 6‑axis robots are mak­ing a come­back in the price area as tech­nol­o­gy advances and costs for units decrease.

Over­all, there is not a clear win­ner in four-axis vs. six-axis robot­ic sys­tems. It is a mat­ter of speed vs. flex­i­bil­i­ty, and ulti­mate­ly, it is up to the cus­tomer to see what their facil­i­ty and appli­ca­tion needs more.
