Brachio · Family workshop · Pre-order

Build a machine that draws.

A one-day workshop for a kid and a parent. Together you build a small two-arm machine that holds a pen, watch it draw its first lines, and take it home.

A 3D rendering of the Brachio design: a dark box holding the controller and a small screen, with a two-part arm reaching out over a sheet of paper and a pen holder at its tip.
The design, drawn from its CAD files. This is the 3D-printed version; on 21 November your family builds the same two-arm machine from foamcore.

What your family builds

Build the arm. Make it draw. Take it home.

  1. Build the arm

    Your family assembles a Brachio from foamcore: a base, two arms joined at an elbow, and a pen holder at the tip. Staff have cut and prepared the parts, so the session is spent putting it together.

  2. Make it draw

    Three small motors go on: one at the shoulder, one at the elbow, and one that lifts the pen. Your kid connects them to a microcontroller and the arm draws its first lines on paper.

  3. Take it home

    Each family keeps its machine and the drawings it made that day, and can keep drawing with it at home.

Questions

What families ask.

What is a Brachio?
A small machine with two arms that holds a pen and draws on paper. Three small motors move the arms and lift the pen, and a microcontroller tells them where to go. Your family builds one, watches it draw its first lines, and takes it home.
Is this a pre-order?
Yes. This is the first time the workshop runs. It goes ahead only if at least 6 families reserve by Friday 6 November 2026. If fewer do, every family gets a full refund by Monday 9 November 2026. We email every family by 6 November either way.
Who is it for?
Kids aged 11 to 14 and a parent. A parent or guardian stays for the whole session and builds alongside their kid. No experience with motors, code, or electronics is needed.
What does it cost?
Each family pays $250 for one Brachio and up to two kids. An extra kid is $50. An extra Brachio is $100. You choose extras at checkout, and the card is charged when you reserve.
How does the referral work?
After you reserve, we email you a referral code. A family that reserves with your code gets $50 off, and you get $50 back on your card for each family that pays with it.
Is it safe?
The motors are small and run on USB power. There are no lithium batteries and no high voltage. Hot glue joints and any knife work are done by MMEG staff. We ask a parent to sign a short waiver before the session.
Where is it, and what time?
In Hyde Park, Chicago. The venue and start time are confirmed by 6 November, and we email them to every family that has reserved.
