Controller Boards
Balance Sensor Assembly
Notes:
The
Controller Boards
receive input from
the gyroscopes and other sensors to
evaluate performance and operating
conditions. They also monitor battery
condition during operation.
The Controller Boards send commands to
the Motors based on information received
from the steering control, gyroscopes and
other sensors.
Redundancy: The two Controller Boards
work in concert and are interchangeable
(but not user-serviceable). Each has the
ability to assume full responsibility for
operation should there be a malfunction in
its counterpart. In the case of a Controller
Board failure, the Segway HT will continue
operation for approximately 10 seconds
while it performs a Safety Shutdown.
Notes:
The Balance Sensor Assembly (BSA) is
composed of gyroscopes and tilt sensors. The
BSA determines the orientation of the Segway
HT relative to the direction of gravity. The BSA
communicates with the Controller Boards to
keep you balanced.
The tilt sensors check each other continuously.
If you perform activities which result in jostling of
the tilt sensors to a point at which the Segway
HT is unable to assess whether or not it is
balancing correctly, the Segway HT will activate
the speed limiter and display the icon indicating
reduced performance. The Segway HT will
return to normal operation when the transient
inputs have been diminished.
Redundancy
: There are five gyroscopes
(angular rate sensors), each oriented in such a
way that any angular motion (pitch/roll/yaw) of
the Segway HT will be sensed by at least two
gyroscopes.
