London based artist Patrick Tresset is widely known for setting up installations and art exhibitions with robotic agents who make stunning artworks. Their forté: sketches and portraits.

Tresset posted the video above on his YouTube channel, featuring a room of robots sketching fine and intricate portraits. The robots work on paper as their hands move across the plane to draw lines and patterns. According to Tresset’s website, his installations “use computational systems that introduce artistic, expressive and obsessive aspects to robots’ behaviour”.

These computational systems are created after thorough research into human actions, and they delve into how humans interact with robots. The amount of minute and elaborate details that go into creating these artworks can be seen in the final, completed works.
