Control Technology provides many educational opportunities. It offers
a subject to study and a general approach to education. With Roamer, Control
Technology becomes a natural extension of design work.
When a child's design ambition extends beyond appearance, Roamer's Control
Features offer new levels of design possibilities: the design of a dog's
tail that wags, a helicopter's rotor that turns, a car whose headlights
turn on when it becomes dark... with Roamer, all these are achievable.
One of the most demanding areas of design is the creation of special
effects for movies. Because the context is so unusual, designers cannot
rely on 'textbook solutions' nor on precedents. They have to rely instead
on their own creative flair and knowledge of technology and design. It
is the same with Roamer design work when using Control features. 'Hard-edged'
technical problems are often heavily disguised by the 'novelty' and the
softness of their appearance. In fact it is in this context that Roamer
design work becomes such an excellent design education tool.
Applications
can be very
basic, like this aeroplane
which uses a DC motor
to turn each propeller.

characters like the Janitor
lie challenging problems
of technology and design.
Craig Rampton from Portsmouth decided that
he wanted to make a frog with legs that would move. The ability to
perceive the problem leads naturally to the exploration of Control
Technology.
Roamer's Control Features
Roamer's Control Features consist of:
Four Outputs capable of operating motors, LEDs, lamps ... anything
requiring a DC current.
One Input Line capable of being operated by touch sensors, limit
switches, push-buttons, light sensors. sound sensors etc.
The Roamer also provides a sensor power supply for light sensors
etc.
This manual does not attempt to explain the science nor the technology
of Control. It does present a way in which Control can be approached
through solving practical design problems.
Valiant Roamer Control Packs
Roamer Control Accessories include several packs useful for design
activities:
