1. Classification by Mechanical Structure

Mechanical structure determines working envelope, flexibility and application scenarios, which is the primary factor for selection.

1. Articulated Robot

The most widely‑used industrial robot, normally with 6 rotary joints simulating human arm motion.

Main features: Superior flexibility, capable of reaching any position and posture within working space; good at obstacle‑avoiding operations in complex environments; large working coverage with small floor footprint.

Typical specifications: Payload 3 kg up to over 500 kg; reach 0.5 m‑3.5 m; repeat positioning accuracy ±0.02 mm ~ ±0.1 mm.

Typical applications: Automotive welding & spraying, 3C electronics assembly, metal part grinding, machine‑tool loading & unloading.

2. SCARA Robot

4‑axis robot with 3 rotary joints plus 1 vertical linear joint.

Main features: Extremely high speed and repeat accuracy in horizontal plane, ideal for fast pick‑and‑place; high vertical stiffness for vertical insertion assembly; compact footprint.

Typical specifications: Payload 3 kg‑20 kg; reach 200 mm‑1200 mm; repeat positioning accuracy ±0.01 mm ~ ±0.02 mm.

Typical applications: PCB electronic component assembly, precision plastic part assembly, food sorting, small‑product packaging.

3. Cartesian Robot

Consists of X, Y, Z linear axes; rotary axis can be added optionally.

Main features: Simple structure, modular design, easy control and low maintenance cost; high rigidity and load capacity, smooth motion; extremely long travel up to tens of meters is achievable.

Typical specifications: Wide payload range from several kilograms to hundreds of kilograms; customizable travel; repeat positioning accuracy ±0.02 mm ~ ±0.1 mm.

Typical applications: Large‑workpiece handling, gantry palletizing, dispensing, vision inspection & scanning.

4. Delta / Parallel Robot

Spider‑type structure; end effector driven by multiple lightweight connecting rods in parallel.

Main features: Ultra‑high speed with hundreds of pick cycles per minute; excellent dynamic response and acceleration performance; stable structure with high stiffness‑to‑weight ratio.

Typical specifications: Payload 3 kg‑10 kg; working diameter 800 mm‑1600 mm; repeat positioning accuracy ±0.1 mm.

Typical applications: High‑speed sorting & packaging for food and pharmaceuticals, fast pick‑and‑place on electronics assembly lines.

5. Collaborative Robot

Designed for safe human‑robot co‑work in shared workspace.

Main features: High safety level with built‑in force sensor and collision detection; stops immediately upon human contact; safety fences are usually unnecessary. Easy programming via drag‑and‑teach and graphic HMI with low technical threshold. Compact and lightweight for flexible redeployment among stations.

Typical specifications: Payload 3 kg‑16 kg; reach 500 mm‑1300 mm; repeat positioning accuracy ±0.02 mm ~ ±0.05 mm.

Typical applications: Multi‑variant small‑batch production, hybrid human‑robot assembly lines, laboratory automation, precision assembly & testing.

2. Classification by Driving Mode

Drive system is the power source, directly affecting equipment performance and operating cost.

1. Electric Drive

Servo‑motor driven, the dominant solution today. High accuracy, fast response, flexible control, energy‑saving and eco‑friendly. Covers over 80 % of industrial applications.

2. Hydraulic Drive

Power generated by hydraulic oil for cylinders or motors. High power and heavy lifting capacity (>500 kg), stable motion and shock resistance; risk of oil leakage. Mainly for heavy‑duty handling, forging and casting.

3. Pneumatic Drive

Powered by compressed air. Convenient air supply, fast action, simple structure and low cost; relatively low accuracy (around ±0.2 mm). Used for light‑duty fast pick‑and‑place such as food sorting.

3. Analysis of Core Specifications

Key parameters for model selection:

Payload: Maximum allowable weight at end effector, including workpiece plus end‑of‑arm tool. 20‑30 % safety margin is recommended.

Reach / Arm Span: Reachable working range. Ensure full coverage of operation area with 15 % margin.

Degrees of Freedom / Axis Count: 3‑4 axes for simple handling; 5‑6 axes for complex spatial tasks; 7‑axis for superior flexibility.

Repeat Positioning Accuracy: ≤±0.05 mm for precision assembly; ≤±0.1 mm is sufficient for general material handling.

Ingress Protection: IP54 for normal environments; IP67 for water‑spray and humid conditions.

Force Control: 6‑axis force‑torque sensor enables precision assembly and adaptive grinding.

4. Summary of Selection Logic

Select industrial manipulators following clear logic: determine mechanical structure by application scenario; define specifications by payload and accuracy; choose protection grade by working environment. Take full‑life‑cycle cost into consideration to achieve optimal return on investment.
