The DRIVE UNIT is the key to the mechanical operation of the wagon. Each unit includes two servomotors that provide for locomotion and steering in tandem. The drive unit’s patented design allows rotation of the wheels at standstill without any damage to the stage floor. Depending on the maximum speed, drive units can move from 500 to 2000 kg. Up to 10 units can be mounted in a single wagon.
The TRIPLE CASTER UNITS have been especially designed to provide a minimum of rolling friction. This helps to provide for high positioning accuracy, even when the navigation system is out of range.
A LASER SCANNER works together with the navigation computer to control the position of the wagon. The scanner can be mounted anywhere on the wagon, including under the floor or on top of scenery. As long as the laser can see a minimum of three reflectors, a repeatability of +/- 5 mm can be expected.
The CONTROL CABINET contains the control and navigation computers, a power supply and an emergency stop system. Two independent radio systems ensure reliability and safety.
The AMPLIFIER CABINET includes four intelligent servo amplifiers. The servos work together with the control computer to dynamically position the wagon.
Sealed BATTERY PACKS provide power for many hours of continuous operation.
The POWER SWITCH includes an emergency stop button and a socket for connecting a mains cable. It is small and can be placed in any accessible position.
All of the wagon components are designed to fit into the wagon frame while allowing for a platform height of 200 mm. Being modular they can be reused in wagons of different shapes and sizes and quickly replaced for service.
