The Penguin Robot Society site, where you can find precious source code and various documentation about the Penguin Robot, has now a dedicated web domain: www.p-robot.com
All the info previously stored under www.robotinfo.net/penguin has been migrated there, but those old pages are still available, in order to avoid missing links and to allow people to find it through old search engines indexes, and they will continue to stay there for a long time.
However, I believe that Penguin Robot deserves a dedicated domain, easier to type and to remember. Any new development will be posted under this new www.p-robot.com address. The site has also been redesigned, and I hope you like it.
Please let me know about any missing link or other error you might find in it.
There is a bug in Penguin-ServoCalibration-v1.1.bpx which means the Walking option doesn't work properly if the tilt range is >255.
I emailed KG yesterday with the fix, Indirect is used as a byte instead of 'Word Indirect' in the first block of the DO/LOOP.
Also when printing the screen, printing stops at $555 whereas it should end at $559.
Switch your Penguin Robot over to Rechargeable Batteries
and Enable a Renewable Power Source!
The Penguin is a great robot with many well designed features.
But to keep it from gathering dust, you need to feed it a good
food diet of fresh batteries. No, not leftovers. No, not those
cheap mixes you're thinking of with one new battery and one
old battery. You must have fresh, fully optimal, batteries or
Penguin will not have enough energy to walk. You see, the
servos require a lot of instantaneous power, unlike the mother-
board, display, compass, infrared transmitters and receiver,
etc. So, unless you want to operate your Penguin without
motion, use new batteries.
After a couple hours of use, you'll need a new set of batteries.
Of course, this depends on how much motion is programmed.
Batteries could last far longer if you're using sound, display,
compass or some other features not related to the servos. To
help matters along with the servo, please do the upgrade with
the electrolytic capacitor on the aux5 port as was previously
described. It will help prevent resets and enable the servos
to start-up more efficiently.
For tests, I am now using a set of rechargeable batteries. The
code name is ICR123A. The batteries with charger were purchased
in China at a cost of US$12. Batteries are rated at 3 volts each and
take about 2 hours to recharge. The charger has a multicolored LED
to indicate charge status. The Lithium Ion battery is a high energy
release battery typically used in camera photo flash applications.
Some texts say the recharge version has a little less power than
the non recharge version but I have not noticed any deviation from
perfect performance.
This battery data is found in the comments from the BAT Penguin code
downloaded at the link. It gives a guide for battery operation and what
constitutes too low voltage.
' Battery Threshold
' -----------------
' Generally, nominal CR123A battery voltages above 5-volts are
' acceptible for normal operating. Below 5-volts and the batteries
' should be immediately replaced.
' Battery Too Low
' ---------------
' If a bad battery set is placed into Penguin, and if the voltage is
' very low, around 4.8 volts or less, previously loaded programs will
' fail.
' -------------------------------------------------------
' rc volts observations
' -------------------------------------------------------
' 103 6.00 rc samples can vary on different penguins
' 114 5.00 below 5 volts and replace battery
' 121 4.60 program errors, fails, erratic behavior
' program won't load properly, display fails
' 126 4.43 battery fluctuating 4.45, 4,44, 4.43
' program going crazy, recyles the reset
' cannot reload program, no basic stamps found
' led is still on and dim
' turn off and on, still cannot find stamp
' 130 4.00
' 3.90 No useable serial ports found
' 3.85 USB device not recognized
' 3.49 LED very dim
' 3.66 no useable serial ports found, led dim

New Interesting Updates
Changes and updates to the Penguin Robot Society' web sites
now include a redirection link at the top of the old web page,
and the new site is updated with new additions to include a new
magazine, and additional BASIC Stamp, Propeller, and Penguin
projects!
Note: Ramboman, you probably would not want to do that unless it's a rechargeable. The stock Rayovac CR123A Lithium Photo battery supplied by Parallax has a higher rating (1400mAh).
Aones cells need a rather complex charger to not kill the cells .
NOTE : LiFe so far is considered to be the most stable Li-xxx cells on the market yet any Li based cell can be ruined from a junky charger .
most just blow up.:jumpin:
I have yet to see A123 ( Aone systems) sell single cells to individuals.
the only way I have found to get a resonble amount of them is in DeWalt batt packs .

However, it's a known fact that if you're programming for long
periods of time, you may want to build a well regulated battery
eliminator.
These rechargeable batteries have already had a series of tests
with Penguin robot and performance was outstanding.
This set of batteries and charger has enabled a
renewable source of power for Penguin.
