Outreach : Gateway CPS

F1 in Schools is an international STEM competition for school children, in which groups of 3–6 students have to design and manufacture a miniature car … using CAD/CAM design tools. The cars are powered by CO₂ cartridges and are attached to a track by a nylon wire.

Some of Christy Williams’ students at the Gateway College Prep School in Georgetown, TX have formed a team to compete in the F1 in Schools program. That team, Aspire TX, sought help from The Robot Group and Brooks Coleman and others have risen to the occasion.

You can see the preliminary results in the YouTube video linked below.

The first prototype completed.

Update on Tami Friedman

Tami’s daughter, Rachel, has established a memorial (blog?) for
Tami’s memory, and please share it as Rachel asked us to do :

Rachel said that an address to send cards would be her own address :

Rachel Jagodowski
86 Waid Rd
Monson, MA 01057

As so much of the web is so very ephemeral, I have taken the liberty of extracting some information from the memorial linked above :

Rebecca (Tami) Tamar Friedman (nee Whaples), of Austin, Texas, passed away peacefully on Saturday February, 8, 2020 after battling a long illness.

Tami was born 07/17/1951 in Bloomington, IN to Dr. George W. Whaples, PhD and Dr. Miriam Whaples (nee Karpilow), PhD. Tami spent her childhood in Bloomington and Westminster, MD before moving to Amherst, MA with her family. She graduated from Amherst Regional High School in 1968.

She moved to Austin, Texas in 1973 where she graduated from University of Texas’ School of Nursing. She lived and practiced nursing in Texas for a number of years before moving back to Western MA in 1987 where she continued working as a nurse and became interested in the work of the Free Software Foundation (FSF) and the GNU project.

In 1990, she moved to Brighton, MA where she worked as a hospice nurse and also worked for the FSF for several years before returning to her beloved home in Austin in the late 1990’s. Tami spent her remaining years staying involved in the FSF community, getting involved in the HAM radio community, cat rescue, and volunteering her time as a nurse to help others.

She was predeceased by her brother, Jonathan Whaples, in 1990, her daughter, Nylah Siddiqi, in 2006, and her nephew, Benjamin Rives, in 2008. Tami is survived by her son, Noah Friedman, and his partner, Carrie Lang, of Seattle, WA; her daughter, Naomi Friedman, and her partner, Matt, of Longmont, CO; her daughter, Rachel Jagodowski, and her husband, Matt, of Monson, MA; her daughter, Esther Friedman, of West Barnstable, MA; her sister, Barbara Rives, of Nantucket, MA; her nephew, Sasha Rives, of Nantucket; and her three granddaughters, Nylah, Analise and Molly Jagodowski.

Tami was very dedicated to her work as a nurse, especially as a hospice nurse. She truly felt that patients who were terminally ill still deserved not only the highest of care but the dignity and humanity that she saw as lacking in much of hospice and elder care. In her honor, please consider making a donation to the Alzheimer’s Association at https://alz.org/ to help advance research of Alzheimer’s and dementia as well as support those who are suffering from those diseases.

February, the cruelest month

The days are short. The weather is colder than might be preferred. Hell! The month only has 28 days 75% of the time. Melancholy abounds even as the cedar pollen counts drop toward zero.

Tom Morin passed away – quite unexpectedly – in February 2007. Now Tami Friedman, another long-time member of The Robot Group, Inc. has followed suit.

From Eric Lundquist comes this missive :

I am sad to report that Tami Friedman KD5RJU passed away the morning of Feb 8.

She passed away peacefully in a nursing home after extended illness.

Right now, there are no arrangements planned, per her daughter Rachel who is taking care of her affairs.

If I get an address for the family to send a card to, I will pass it
along, but since she has no family in Texas, there won’t be any
services here.

DE Bob WB5AOH

Rest in Peace, Tami.

Officers and Board Members for 2020

At the Annual Business Meeting on 2019-12-08, an election was held and the results were ratified by the Board of Directors.

Our officers and board members for 2020 are

Hats off to the new leadership for their service in 2020! Thanks to the previous leadership for keeping the thing rolling with wheels on the road in 2019!

Quadcopter build class?

Can I get a quick show of hands from any members interested in doing a quadcopter build if I do a class?

Brooks Coleman Lil’ Deuce

The Lil’ Deuce frame I got from Dalton is really turning out to be a lot of fun and you can build one out for under $100. You can get a cheap, compatible 6-channel radio for about about $50 and same for the goggles so total cost would be $200 if you need everything.

You can get extra receivers for the radios for around $10 to $20 that can also work for controlling robots. Also, extra cameras with transmitters around $20 for the video if you want to telepresence (the kids call it FPV for First Person View) your bot.

These things are a blast to fly around indoors and you can set the video transmitters to the minimum 25mw so you don’t need the HAM license required for the higher power levels. Eventually I’d like to offer HAM test training classes too. So … anyone?

Here’s a couple of videos I did with the Lil’ Deuce, and don’t worry, it’s on horizon mode so no dizzying dives or loops. Also check out my latest addition to the effort of blending moving features to the indoor course.

Yamautomaton, a calligraphic automaton

[Posted on behalf of Yama Ploskonka by rutrohverlord]

This device, designed and built by Robot Group member, Yama Ploskonka, appeared in a cruder form at Maker Faire Austin on May 04, 2019.

The Yamautomaton, a computer-controlled machine originally designed for research in kinesthetics of calligraphy, actually delivers a pretty good hand! Here making a copy of the Canticle of the Creatures, a praise prayer by St.Francis, imitating the hand (font or typeface to y’all) of the oldest manuscript in Italian, c. AD 1270. The machine was built in Austin, Texas, from parts of a homespun CNC originally from 2018. Completing these two sheets of fine calligraphy would take a practiced professional a good couple days. That’s too much work. To save effort, I only spent 6 months building the machine, developing the software, even figuring the right ink-gum-pigments mix. Saving work and time, that’s my motto!

Yama reports that, after just a few months of additional work, the device has now reached ‘production’ reliability.

“I just drop a file with tagged text, and the machine does the rest (of course I have to mother the pen’s ink supply, and set the paper, but that would be the same if doing calligraphy by hand).”

He continues, “I seem to find very few ‘practical’ writing automata out there, seems the concept is a bit abandoned. Yes, of course, essentially it’s just a CNC, conceptually not that much beyond an EggBot, and, yes, it would take just a few rods to transfer the movement to a more humanoid arm and hand. It might be that the actual challenge is then really in the software.”

“The text file goes in as text, including dimensions for the paper, column locations, then coordinates for each stroke in each character come as a CSV spreadsheet. Both get slurped by some Python code (150 lines), that spits out Gcode (for red, gold, black), and on to the CNC.”

Future developments include another attempt at Chinese writing.

“It proved too complicated, so I did a ‘step back to better jump’ by going first to Blackletter (Fraktur, like Gutenberg font), then to this medieval hand. That did help me figure out and pass several limitations that my software and conceptualization had, so I feel more ready now for what is probably still the most complex writing system in use, Chinese. As a fringe benefit, the code is more able to be ‘universal’ … potentially being able to deliver any hand that has been compiled.”

The Yamautomaton (likely a tentative name) is able to travel. If y’all have a venue, please speak up.
