What type of actuator is most commonly used in industrial robotic joints?
Answer: Electric servo motor
Electric servo motors are most commonly used in industrial robot joints due to their precision, speed control, and repeatability.
Which component of a robotic arm directly holds and manipulates workpieces?
Answer: End effector
The end effector is the tool or gripper attached at the end of a robotic arm that directly interacts with workpieces.
What is the primary function of a harmonic drive in robotic joints?
Answer: High gear reduction with zero backlash
Harmonic drives provide high gear reduction ratios with zero backlash, making them ideal for precision robotic joint applications.
Which encoder type retains absolute position information even after a power loss?
Answer: Absolute encoder
Absolute encoders retain position information even after power loss, providing a unique position value for every shaft angle.
What is the Denavit-Hartenberg (DH) convention used for in robotics?
Answer: Systematic description of robot kinematics
The DH convention is a standardized method for systematically describing the kinematic chain of a robotic manipulator using four parameters per joint.
Which robot configuration uses three mutually perpendicular linear axes?
Answer: Cartesian/Gantry
Cartesian or gantry robots use three mutually perpendicular linear axes (X, Y, Z) for straightforward, predictable motion in rectilinear space.
