Our cost
|
- WAP = $0
WRT54G?
- Manifold for I/O = $50
- Software for Manifold = $300
- Time to develop/manufacture Manifold = 2hr
Note: The Linksys WAP lacks most I/O.
A small board called a manifold provides plenty.
The two boards will communicate via a serial port.

- Rabbit development kit = $400
- Manifold for I/O = $50
- Software for Manifold = $300
- Time to develop/manufacture Manifold = 2hr
Note: Rabbit doesn't seem to include analog I/O.
It really isn't clear from the catalog listing.
A small board called a manifold provides plenty.
The two boards will communicate via a serial port.

Linksys -- half the cost

|
OS
|
Linux in C. Soft real time
|
uCOS2 in C. Hard real time
|
Rabbit -- Lower latency
|
|
HW specs
|
- 8MB RAM
- 4MB flash
- 40MHz at least. Likely more
- 10-baseT
|
- 256KB RAM data
- 512KB RAM program
- 512K flash
- 44MHz
- 10-baseT

Linksys

|
Robot usable I/O
|
- 40 digital I/O (manifold)
- 12 analog (manifold)
|
- 44+40 digital I/O (included+manifold)
- 4 digital I
- 4 digital O
- 12 analog (manifold)
- 12 analog (manifold)
|
Neither -- Both are overkill
