Different Robot Varieties

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

Different Robot Varieties


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.
