A robotic arm is a mechanical device designed to mimic the movement and functionality of a human arm. It is widely used in industries, research, and medical fields for precise and repetitive tasks.
Components of a Robotic Arm
- Joints & Links – Allow movement and flexibility.
- Actuators – Motors that power the joints.
- End Effector – The tool attached at the end (e.g., grippers, welding tools).
- Sensors – Provide feedback on position, force, and environment.
- Controller – The “brain” that processes commands and coordinates movement.
- Power Supply – Provides energy for operation.
Types of Robotic Arms
- Articulated Robotic Arm
- Multiple joints for flexibility (e.g., industrial robots).
- SCARA (Selective Compliance Articulated Robot Arm)
- Ideal for high-speed assembly and pick-and-place tasks.
- Cartesian/Gantry Robotic Arm
- Moves in straight-line (X, Y, Z axis) for precision.
- Cylindrical Robotic Arm
- Rotates around a central axis with linear movement.
- Polar/Spherical Robotic Arm
- Uses a rotating base with a telescoping arm.
- Delta Robot
- Used for fast, lightweight pick-and-place operations.
