Articulated Robot Arms: Overview and Types

Articulated robots are commonly called robotic arms, jointed-arm robots, or multi-axis robots. In the injection molding industry, specific types are known as take-out robots, sprue pickers, side-entry robots, cobots (collaborative robots), or palletizing robots depending on their axis count, entry geometry, and intended application.

Articulated robot pricing varies widely based on payload capacity, speed class, axis count, and application. Entry-level pneumatic sprue pickers are the most cost-effective, while high-end precision take-out robots, super-high-speed IML models, or heavy-duty large-part robots command higher investment.

An articulated arm is a robotic structure comprised of rigid links connected by rotary joints that allow movement across multiple axes. In manufacturing, articulated arms are used for tasks including part extraction from molds, assembly, palletizing, inspection, and machine tending — delivering programmable, repeatable motion suited to high-volume production environments.

Articulated robot arms are used across plastics injection molding, automotive tier-1 and tier-2 supply, medical device manufacturing, electronics assembly, food and beverage packaging, pharmaceutical packaging, and consumer goods production. Yushin America's robots serve these sectors through dedicated take-out, side-entry, cobot, and palletizing configurations.

A take-out robot extracts fully molded parts from the mold using servo-driven 3-axis motion, handling complex EOAT and synchronized downstream processes. A sprue picker is a simpler, lower-cost device — often pneumatic or single-axis servo — designed only to remove the sprue or runner, without extracting the finished part.

Yes. Yushin America's SX-41 side-entry robot is ISO Class 6 certified per ISO 14644-1, using sealed bearings, FDA-grade lubricants, and a minimal-particulate motion profile. Clean-room-compatible configurations are available for medical device, pharmaceutical packaging, optical, and electronics micro-molding cells requiring particulate control.
