Keypads Change
Roamer |
|
|
| |
Standard Roamers come
with appropriate keypads. You transform
your Roamer by putting one of the other
Keypad Modules on the same Roamer Base Platform. |

Keypad |

|
| |
You do not need
to buy a different Keypad Module for
each Standard Roamer. You can download,
into a Keypad Module, any of the behaviors
from the Standard behavior CD. The
Keypad Module is like a
Concept Keypad - change the behavior
and the Graphic and you have a different
robot. |
|
|
| |
In principle each Keypad
is kept as simple as possible by containing
only the keys needed for the Standard operation.
However, you may want to add to the features
to suit a project (see Roamer Characters).
To do this you modify the behavior using
the tools in RoamerWorld by defining the
User Keys. The CD includes a number of popular
modified Standard behaviors - for example
a Primary Roamer with keys to operate pen
up and pen down commands. |
|
|
| |
Early Years Roamer |
|
|
| |
This is the simplest
of the Standard Roamers. You program Roamer
using counting paradigms: to make it go
forward 2 you press the forward button twice.
Similarly to make the Roamer stay still
and quiet for 2 seconds or turn right through
2 quarter turns. |

K2 Roamer |
|
|
| |
The K2 Roamer introduces
the more conventional syntax of pressing
a key for direction and a number to tell
the robot how far to move. It also introduces
the powerful LOGO idea of repeat. Mathematics
is sometimes defined as the science of patterns.
Using the repeat function helps students
develop their pattern recognition skills.
With all the new features these patterns
are not restricted to the geometric movements
of Turtle Graphics. It also applies to sound
levels, music, speed and power drive features
introduced in this behavior. |

 |
|
| |
Primary Roamer |
|
|
| |
The Primary Roamer
makes the commands for features like
music and speed more general. One
of the big things introduced here
is the idea of the procedure. Again
this is essentially about more complex
forms of pattern recognition. This
is one of the most powerful and underused
features of LOGO and the Classic Roamer.
Procedures are fundamental to the
notion of problem solving. The process
of breaking problems down into sub
problems, solving these individually
and then combining these "mini" solutions
to gain an overall resolution is a
key skill procedures will help develop. |
|
|
 |
|
| |
The other big feature
of Primary Roamer is its gentle introduction
to control. If you have used the Pen
Up and Pen Down modification to K2
or Early Years Roamer you will have
already done some of this work. Now
there is a generalised key to operate
inputs and outputs in a very simplified
manner, which lays a foundation for
work with Junior Roamer. |

|
|
| |
This contains the full
Procedure, the generalised programming of
features like speed, and the full Control
Features. The robot comes with a single
Control Pod, which in addition to the Input
and Output on the Roamer Base Platform provides
a further three inputs and three outputs.
The behavior also supports the programming
of servo motors either directly or through
relays. |
