Captives is a sculpture series by London-based artist Davide Quayola. The series was inspired by Michelangelo's "Non-Finito" technique, which leaves part of the sculpture apparently unfinished, making it appear as though the figure is trapped within the block of material.

For his group exhibition in Seoul, Quayola wanted to fabricate two 2-meter high sculptures using High-Density Expanded Polystyrene (EPS) in South Korea. Since robotic milling of a sculpture of this size was unprecedented in Korea, everything from material sourcing to tool selection had to be learned from scratch.

To materialize the complex shape of the sculpture, a 7-axis industrial robotic arm was necessary. An additional rotary axis was connected to the Nachi ST210F 6-axis robotic arm to achieve this.

The sculptures were exhibited to the public at the Peaceminusone exhibition from June 9 to August 23, 2015, at the Seoul Museum of Art.
