Robot types can be classified by body form, motion structure, task and deployment environment. Industrial arms are often classified as cartesian, cylindrical, SCARA, articulated or delta robots. Mobile robots, drones, humanoids, service robots and exoskeletons are classified by different physical constraints.
The robot form affects what the machine can reach, how it carries load, how safe it is near people and what software is needed.
Key facts
- Cylindrical robots combine rotary and linear movement around a cylindrical work envelope.
- Exoskeletons are wearable robotic systems that support or augment body movement.
- Industrial robot classification is based on mechanical structure and motion axes.
- Form should be linked to task, payload, reach and safety.
Robot types comparison
| Robot type | Motion structure | Common task | Strength | Limitation |
|---|---|---|---|---|
Cartesian | Linear X-Y-Z axes | Pick and place, CNC loading | Simple geometry | Large frame |
Cylindrical | Rotary base plus linear axes | Machine tending | Good around a central column | Limited workspace shape |
SCARA | Horizontal articulated motion | Assembly and packaging | Fast planar motion | Limited vertical flexibility |
Articulated | Multiple rotary joints | Welding, handling, assembly | Flexible reach | More complex control |
Delta | Parallel arms | High-speed picking | Very fast | Lower payload |
Cylindrical robot explained
| Feature | Description |
|---|---|
Workspace | Cylindrical volume around the base |
Motion | Rotation plus vertical and radial linear movement |
Typical use | Handling, loading, assembly and machine tending |
Limitation | Less flexible than articulated arms for complex orientations |
Exoskeleton types
| Type | Body area | Use case | Actuation |
|---|---|---|---|
Passive | Back, shoulder or legs | Load support | Springs or mechanical assistance |
Powered | Lower body or full body | Rehabilitation or industrial support | Motors or actuators |
Medical | Legs or arms | Rehabilitation | Controlled actuators and sensors |

FAQ
What are the main types of robots?
Common types include cartesian, cylindrical, SCARA, articulated, delta, mobile, humanoid, service, drone and exoskeleton robots.
What is a cylindrical robot?
It is an industrial robot form that uses a rotating base and linear motion to work inside a cylindrical envelope.
What is a cylindrical robot example?
Cylindrical robots are used in machine tending, material handling and assembly-style tasks where their work envelope fits the process.
What is an exoskeleton?
An exoskeleton is a wearable robotic system that supports, assists or augments human movement.
How does robot form affect performance?
It defines reach, stiffness, speed, payload, workspace, safety and integration complexity.
