I had not known... http://www.ebay.com/itm/Parallax-Growbot-Robotics-Stamp-II-and-Serial-Solder-1998-/171667792711?

A priceless relic circa 1998? Ken, do you need one for your archive?

    I have a modified GroBot board laying around. Very expandable for some 3 pin header devices. Good if you wand to use 2 app modules. I found the older servos had some issues. I offered $50 on the ebay one you mentioned but no deal.

    That's almost worth it for the blue anodized chassis.

    Agreed, mine for $60 as of tonight. Had to have "Old Blue" for my collection.

    It's amazing that Parallax has been using the same basic robot design for almost 20 years.

    Very interesting. Never heard of this either but searching the forums for growbot or grobot comes with quite a few results. Like the blue anodized frame also. I like the idea of a "soldering required" version of the BOEBOT. I think this format should be revisited.

    The Boe-bot chassis is a great design with plenty of attachment points, and rock solid because it is thick aluminum. I've seen some competing chassis from another vendor and their quality wasn't close. It would be hard to improve upon. With some of the newer high torque CR servos you can use it as the drive for a good size robot.

    JEALOUS! Thank for the link to the documentation too! Interesting stuff. Wonder who wrote that? Was Andy around back then?

    No, but thank you.

    Parallax was before our time when we created this, both in name and function. Today "Growbot" is a hydroponic mobile garden platform for you know what.

    Actually, that robot brings back interesting memories. It was the first significant product I worked on by writing the assembly and programming instructions. The assembly documents were prepared in MS Word in a layout that allowed us to print them, staple in middle and put into the kit. Was a real pain to handle the page numbering, too! Russ Miller did the chassis design over a weekend and John Barrowman designed the PCB in a couple of days. We started this project in October and shipped the first units a few days before Christmas. Our standards have really increased since then - thankfully our customers gave us a second chance. . .or a third, or a fifth!

    Anyway, I have a GrowBot on my desk (the robot type, that is).

    The story of the origin of the Boe Bot ancestor is very interesting
    However I googled : Russ Miller and John Barrowman and the result was:
    Russ Miller :internationally known as one of the top drummers of today
    John Barrowman :a Scottish-American actor

    Since everyone loves the BOEbot chassis so much, Parallax could have each batch they produce anodized a different color. This would make them collectable among those of us that hoard, I mean collect, Parallax products. After a few years of "collecting" you could have a colorful little fleet of BOE bots running around. It would certainly be good for repeat, repeat, repeat sales of the cute little guys!!

    I know my three or four little silver guys would soon be jealous and pressuring me to get with it and add some colors!

    Well, they are applying that color strategy to the Scribbler line. Place your bets, what color will the P2-based S4 be in 2019?

    I still want chrome, even a limited edition one.

    New and unassembled! Great find Andy, it's likely worth even more if it's anything like an unbuilt Heathkit.

    Ken might need one for his archives. Maybe I should nab it ASAP for a future Toddler exchange. :)
  • PublisonPublison Posts: 12,366
    May be a later model with the non anodized chassis. I will wait for a blue or gold.
  • PublisonPublison Posts: 12,366
    Looks like this is an upgrade to the standard BOEBOT chassis.

    I found this guy in a box today (!) and realized that I never did anything with him, partially because the O-ring tires needed replacing. I found some skinny but serviceable replacements at my local Ace Hardware store and had to bang out a quick Figure 8. I'll include this video in the Figure 8 thread, because I believe this will be the first Growbot there.

  • PublisonPublison Posts: 12,366
    Private Video? Can not view.
  • ercoerco Posts: 20,257
    Sorry, there was a delay since the video uploaded slower than my concurrent post. Should be OK now.
  • PublisonPublison Posts: 12,366
    Supurb! Nice video with Theo also!
  • ercoerco Posts: 20,257
    Thanks Jim. I still like to do a momentary stop between circles to show clearly when one ends and the next one starts for reference. Like some other bots I have tried, this one does a slight turn if you just stop sending servo pulses. That is, when the servos are coasting to a stop, they don't do it evenly, which messes up the alignment for the second circle. The solution is to send PULSOUT 750s to both servos (their stop/null point) which actually applies dynamic braking and slams the wheels to a sudden stop, quite visible in the video in the middle and end.

    Noteworthy that Growbot requires a 9V battery (for the BS2) in addition to 4xAA cells (servos only). The 3-position DPDT toggle switch functions the same as the 3-position slide switch on BoeBot: off, stamp on only , stamp & servos on.

    That unbuilt Growbot kit is still listed for $100: http://www.ebay.com/itm/PARALLAX-GROWBOT-ROBOT-KIT-NEW-/141925023882
