A parallel robot connects its end-effector to the base through multiple parallel kinematic chains. Examples include the Stewart platform, delta robot, and many industrial pick-and-place arms.

Think of it like a household object that does the same job — the underlying idea is the same, just adapted for robots.
Why it matters
Without parallel robot — complete guide, many concept systems in robotics simply couldn't work.
Parallel Robot
What is it?
A parallel robot is a closed-kinematic-chain robot — its moving platform is connected to a fixed base through multiple independent legs, all working in parallel. This is the opposite of a serial robot, where joints are stacked one after another.
How it works
Because each leg shares the load with the others, parallel robots are extremely stiff, fast, and accurate — but their workspace is smaller than serial arms. Common designs: the Stewart platform (6 legs, 6 DOF, used in flight simulators and machine tools), and the delta robot (3 parallel legs ending in a triangular platform, used for super-fast pick-and-place).
Real-world example
Pharmaceutical factories use delta robots to pick pills at 200 picks/minute. Flight simulators use Stewart platforms to mimic aircraft motion. Machine-tool spindles increasingly use parallel kinematics for precision milling.
Why it matters for robotics
Parallel robots solve the niche of fast, accurate, small-workspace operations that serial arms can't handle. Delta robots are a frequent interview topic for manufacturing robotics roles.
