For applications requiring reach far beyond its base, which robot types are suitable?

• A. Polar and articulated robots
• B. Cylindrical and Cartesian robots
• C. Articulated and Cylindrical robots
• D. Box framed Cartesian robot

Answer: (A)

The ability to reach far from the base comes from how the arm is allowed to extend and maneuver. A polar (cylindrical) configuration uses a rotating base with an extended arm, which creates a large radial reach outward from the base without needing a big base footprint. An articulated arm adds multiple rotary joints and links, giving substantial reach in 3D space and the flexibility to reach around obstacles. Together, these types maximize how far the end effector can get from the base, more effectively than structures that are limited to linear axes or a box-shaped workspace. That’s why polar and articulated robots are the best fit for applications requiring reach far beyond the base.
