Totemobile weighs 4600kg fully assembled with dimensions of 2.5m x 5.2m by 3.0m tall in its retracted position. It can extend to a maximum height of 18m, although a lower display height is possible if 18m cannot be accommodated. A spectator barrier around the machine would have rectangular dimensions of 4.5m x 7.2m. The Totemobile can only be displayed indoors.

The sculpture requires electrical service of four-wire, 230V, 60A A/C 50 Hz.

A forklift with a minimum capacity of 5000 kg (at 1.25m center) is required to unload the machine. Approximate floor loading is 360kg/m3.

Totemobile requires three full days for setup. Five Amorphic Robot Works personnel are the required crew.

The Totemobile is composed of 27 electro-mechanical linear actuators and motors for its movement of main components. Totemobile’s form is also accented by the addition of 10 low pressure inflating pneumatic elements. All of Totemobile’s main actuators are safety checked by double redundant travel sensors, position sensors, and tilt sensors. All of Totemobile’s systems are operated automatically by an Allen Bradley industrial Programmable Logic Controller.

The main system of lift for the Totemobile is based on three four-stage custom designed telescoping aluminum assemblies, each driven by a high load Parker linear actuator with dual chain and sheave pulley extension systems. A state-of-the-art cable track houses all cable and hose systems for smooth, efficient, tangle free cable management.
