A robotic arm is a programmable manipulator that moves a tool through a workspace to perform tasks such as handling, assembling, inspecting or teaching automation. The term covers several different robot configurations and audiences—from industrial systems to classroom kits—so the right choice depends on the task, workpiece, workspace and safety requirements.
What is a robotic arm?
A robotic arm is a manipulator made of connected or sliding segments that move around one or more axes. An axis is a direction of linear or rotary motion. At the end of the arm, an end effector—such as a gripper or another tool—interacts with an object or the surrounding environment.
For industrial robots, the International Federation of Robotics (IFR) uses the definition based on ISO 8373:2021: an automatically controlled, reprogrammable, multipurpose manipulator programmable in three or more axes for automation in an industrial environment. A robotic arm is not one specific shape, model or product category.
What are the main types of robotic arms?
Robotic arms are often classified by how their joints or segments move. The configuration affects the shape of the workspace and the directions in which the arm can move.

| Configuration | How it moves | Distinguishing feature |
|---|---|---|
| Articulated | Three or more rotary joints | Linked rotary joints give the arm a jointed form. |
| SCARA | Two parallel rotary joints | Provides compliance in a selected plane. |
| Cartesian or gantry | Three prismatic joints | Moves along linear axes. |
| Parallel or delta | Arms arranged in a closed-loop structure | Uses a parallel rather than a serial chain of joints. |
| Cylindrical or polar | Configuration-specific combination of rotary and linear motion | Named for the geometry of the resulting workspace or motion arrangement. |
These are configuration categories, not guarantees of a particular payload, reach, speed, precision or suitability. Those characteristics vary by model and installation.
What is a collaborative robot?
“Collaborative” describes a robot system or application designed to share a workspace with people; it is not a particular arm geometry or a guarantee that an arm is safe in every setting. A collaborative application combines the robot and its end effector with controls, workspace layout, task design and organizational safety measures.

EU-OSHA distinguishes coexistence, cooperation and collaboration as different kinds of human–robot interaction. Its discussion references the revised 2025 EN ISO 10218 series, which distinguishes requirements for the robot from requirements for integration and safeguarding. These are European references; applicable standards and legal duties depend on the country and workplace.
What are robotic arms used for?
Industrial arms can be part of applications such as welding and cutting, flexible assembly, packaging and palletizing. IFR also notes that standardized work cells can make some small-volume production tasks automatable. Whether automation is suitable or cost-effective for a particular operation depends on its requirements and implementation; these category-level examples do not establish a business case for an individual workcell.

Education and classroom use
An educational robotic arm kit is designed to teach robotics or automation rather than serve as a production system. VEX describes its CTE Workcell as a classroom system for high school and post-secondary programs, with a six-axis arm, integrated sensors, pneumatics, curriculum and activities that simulate automation tasks such as palletizing. Its stated audience and features make it a learning product, not a substitute for an industrial production installation.
How do you choose a robotic arm?
Start with the job the system must perform, then compare arms against the entire application—not just the arm itself. Without a defined task, industry, payload, reach, budget and location, there is no evidence-based single best model.

- Choose a configuration and required motion. Consider the workspace shape, axes, approach directions and orientations required to reach each part of the task.
- Check payload and reach. Account for the workpiece and the tool mounted at the arm’s end, and confirm that the arm can reach the required positions throughout the workspace.
- Set performance requirements. Establish the cycle time and the precision or repeatability the job needs. Compare those requirements with model specifications; the sources cited here do not establish numerical, model-by-model performance comparisons.
- Plan the end effector and integration. Check the gripper or other tool, controller, programming, sensors, mounting and workcell compatibility. Verify that any end effector is mechanically, electrically and software-compatible with the selected arm, and suitable for its payload and safety setup.
- Assess deployment and safeguards. Include risk assessment, safety functions, installation, training, maintenance and the rules that apply in the installation’s jurisdiction.
What safety issues should you consider?
In a U.S. workplace, OSHA groups industrial robot hazards according to the application and the stage of work. Impact, collision, struck-by and caught-between hazards may arise during system integration, operation, programming, teaching or maintenance. Safety must therefore be assessed for the complete application, not inferred from a label on the arm.
The appropriate safeguards depend on the work and the kind of contact that could occur. OSHA notes that power and force limiting can be relevant when contact with a moving robot is expected, while speed and separation monitoring can apply when contact is not intended. Neither function removes the need for application-level risk assessment.
