The Pitsco Lego Dacta catalogue has two touch sensors:
N79888 a 2x4 brick with attached wire: $18.50
N77991 a 2x3 brick using seperate std 2x2 brick lead connectors: $11.00
(you get 4 of these sensors in the robolab starter set).
Is the first just an older variant or are there other differences?
They just sent my a $100 gift certificate as a "drawing winner", so
I'm pondering various goodies from their catalogue (pneumatics?, angle
sensors? motors?, more beams/plates/links/gears/turntables... :-).
ROBOLAB review:
So far I have found my initial plunge into legobots (the ROBOLAB starter
set (N979780 + two RCXs + IR tower) to be a great initial assortment
of stuff. However I've given up on the ROBOLAB sw and have switched
over to NQC with vastly better results. The ROBOLAB sw does work, its
cute, but I caused it to panic twice on my first program, and found
its graphical editing style very tedious once the cuteness wore off.
I have been programming for nearly 30 years (oh good grief) so admiedtly
ROBOLAB was _NOT_ designed for me. But having also helped some 7th/8th
graders learning to program, I'm not sure they wouldn't have exhausted
this pretty early as well. LabView's claim to fame (it seems to me, I
have their evaluation/demo CD) is controling a variety of data sources
and sincs, potentially collecting substaintial data and all in a
heterogenous env (lots of different equip) but not doing that
much complex programming. So I'm not sure its really that good a
match for legobots, where the data sources/sincs are simpler, but
you want more complex control. Maybe at the 4th-6th grade level it
would be appropriate (and its actually pretty cheap so I have no
regrets at all about trying it out, and still use it to init the
firmware when needed since ROBOLAB does not provide a seperate firmware
file that NQC could download).
