Three ways
to control HUGO
The HUGO guidance system is at three
levels and will use the best available part to complete
its purpose. If one level fails the best available lower
level will do the work instead.
At lowest level Hugo is not self-aware
but you will still be able to run the complete model.
A minimum requirement is that four wheel control modules
are operational, at that time 75% of the elechtrical
system is down but Hugo will still go.
That is done by a three level control
operating system. It was originally designed to run
on the industry computer with windows XP but it can
run by itself only using the internal network of ten
16-bit processors. The network is a CAN bus like those
being used in industrys and automobiles nowdays. Really
anything can happen without errupting the network. Any
part left of the network will continue inter communicating,
continue to solve problems, control the motors and try
to complete any given task. If the master computer fails
there is a guided control to do the job instead. If
finally that part fails there is a protected driver
board to run the HUGO system completely too. At that
stage, however, the operator cannot rely on any helpful
tactics to complete the job.
