We also supply our so called "DisplayWalker" which is an electric driven, radio controlled advertising column in different version according to customers demand.
It got an very stabil 4-wheel suspension with integrated radio contolled receiver, liithium battery, an 200W electric motor and high end battery charger which charges the batteries within 2 hours.
The column is steered by an separate person that is walking with an radio control transmitter from up to 50m away and so it can self drive throught as for example shopping centers, exhibitions, walking zones or wherever without seeing who is moving this promotion column.
Highest attention is guaranteed because peoples would wonder how this column is moving. Maybe it´s a roboter?
