When evaluating a robotic hand, you must prioritize Degrees of Freedom (DoF), which determines the dexterity and range of motion. For industrial automation, a 3-finger or 4-finger design is common, while prosthetic or research applications may require 5-fingers with 15+ DoF. Additionally, check the payload capacity (ensure it exceeds your heaviest workpiece by at least 20%) and the gripping force (measured in Newtons). Look for high-precision encoders and brushless DC motors to ensure longevity and sub-millimeter repeatability.
