are large autonomous robots that move incredibly slowly. Sloth-bots, influenced by their interactions with people, imperceptibly reconfigure the architecture.

Sloth-bots build on robotic technology developed by Dr Guido Bugmann famously incorporated into Donald Rodney’s “Psalms”.

"Psalms" was exhibited in the South London Gallery as a part of Rodney’s last exhibition entitled "Nine Night in Eldorado", in October 1997.

The wheelchair uses 8 sonar sensors, shaft-encoders, a video camera and a rate gyroscope to determine its position. A neural network using normalised RBF nodes encodes the sequence of 25 semi-circular sequences of positions forming the trajectory.

The control system comprises a laptop PC 586 running a control program written in CORTEX-PRO, and linked to a Rug Warrior board built around the 68000 microcontroller.

Sloth-bots use additional technology to link between the Arch-OS vision tool and the autonomous architectural forms.
