Delta Robot
A delta robot is a parallel robot in which three arms connected to a common base drive a small moving platform, giving very high speed and acceleration for light pick-and-place work such as packaging food, pharmaceuticals and electronics.
Three parallelogram arms, each driven by a motor on the fixed base, connect to a moving platform that stays parallel to the base. Because the motors are stationary and the arms are light, the moving mass is low, allowing very fast motion. A fourth rotary axis is often added through a telescopic shaft to rotate the tool. The design was developed in the early 1980s by a team led by Reymond Clavel at EPFL in Switzerland.
Delta robots are typically mounted overhead above conveyors, picking products and placing them into trays, cartons or flow wrappers, often guided by vision and conveyor tracking. Hygienic designs are used in food and pharmaceutical packaging, and smaller versions sort and assemble electronic components.
Their working volume is compact relative to the robot's size, and payloads are low. Cycle time depends on the pick pattern, product mass and gripper. Overhead mounting, high speeds and nearby operators mean guarding and access interlocks must be defined through risk assessment.
Key points
- Parallel kinematic design with three arms driven from a fixed base
- Low moving mass enables very high speed and acceleration
- Typically mounted overhead for conveyor picking and packaging
- Payload and working volume are small relative to robot size
Where AiVibe comes in
AiVibe designs and manufactures the AiAmbA AI Factory, whose edge devices and AI agents let people talk to robot controllers in plain language. Robotics perception is an AiAmbA use case, and robot safety functions follow ISO 10218 and never depend on the AI layer.
