Robotics Interview Questions and Answers

The robot base, world, and tool coordinates are located at the zero position.

• The robot base coordinate represents the position of the robot's base or origin.

• The world coordinate represents the position of the robot in relation to the external environment.

• The tool coordinate represents the position of the robot's end effector or tool.

• When all three coordinates are at zero, it means the robot is in its initial position.

• These coordinates are typically defined using a Cartesian c...read more

Yes, digital filters can be used to process an analog signal.

• Digital filters can be used to remove noise from an analog signal.

• Digital filters can be designed to have specific frequency response characteristics.

• Examples of digital filters include Butterworth, Chebyshev, and Elliptic filters.

Aliasing is a phenomenon where a signal is sampled at a lower frequency than its original frequency, resulting in distorted output.

• Occurs when a signal is undersampled

• Results in distorted output

• Can be reduced by increasing the sampling rate

• Common in digital signal processing

• Examples include moiré patterns in images and the wagon-wheel effect in videos
