Physical dimensions, electrical specifications and parts information.
The size and accelleration capabilities of the WalkMouse enables natural interaction up to walking speed. Starting from the centre, the user is able to walk in any direction with a maximum step length of 900mm.
WalkMouse physical specifications:
Diameter 1.8 meters / 5.9 feet
Height 68.5 mm / 2.697 inches
Weight 65 kg / 143 lbs
Max walking velocity 0.5 meters / 1.64 feet per second
The use of a permanent magnet AC synchronous motor allows for precise control and high power in a small package, placed underneath the centre plate. A frequency inverter is used to control the motor's velocity with high resolution based on the user's position, velocity and acceleration.
WalkMouse electrical specifications:
Voltage 220 - 240V, 50Hz AC single phase (110V, 60Hz with converter)
Power 0.6kVA continuous / 1.2kVA max
The active surface of the floor is built with steel coils that exhibits special characteristics that enable circular bending and torsional stiffness. A belt drive unit connects all coils to the motor, which thereby creates a circular surface where a user is transported towards the center at all times. Furthermore, the use of belts creates a drive unit that can facilitate walking on top of it. The coils are in turn suspended on rollers to minimize friction and are kept in place with plastic restrainers. Custom rubber foam is placed under the rollers to maintain a low noice level.
