The root README has the timeline of all generations since 2009. Each generation folder explains its hardware and what is in it. .gitattributes turns off line-ending conversion so all files stay as they were.
2011–2012: FireFly (Arduino Mega + SSC-32)
In June 2011 the robot was rebuilt around an Arduino Mega 2560 and a Lynxmotion SSC-32 servo controller,
with a new body and bracket (../original-frame/). The Mega does the inverse kinematics and sends
#n Pxxxx Txxx commands to the SSC-32 over Serial1 at 38400 baud. The serial banner calls it "FireFly".

Each folder is an Arduino sketch (or library); successive versions are successive commits, so
git log -p -- <folder> shows what changed.
| Folder | Dates | What |
|---|---|---|
2011-nunchuk/hexapod_oud/ |
2011-10, 2011-12 | Wii Nunchuk input, fixed walking sequences, IK, SSC-32 output. Second commit = hexapod V2 29-12-11.rar |
