COMPAREE VERDICT

ArachnoBot is a great-looking six-legged printed robot with a satisfying, insect-like walk — 18 servos (three per leg), a printed carapace, and TPU claws that give it quiet grip. Rob's Tech Workbench organized the print package nicely and backs it with a full YouTube tutorial series. Be clear on how it's split: this repo is the STL parts and printing docs, while the control code lives in a separate tutorials repo and the videos, and there's no wiring BOM or STEP CAD here — you'll bring a controller (a Servo 2040 or a Raspberry Pi) and follow the series for the electronics. It's derived from the popular MakeYourPet hexapod, so there's a real community around the design. A rewarding several-weekend build for someone who enjoys many-legged robots.

NOT IN THE REPO

  • —This repo is STL parts plus detailed printing docs — a well-organized print package
  • —No firmware, no STEP CAD and no wiring BOM in this repo — the code lives in a separate tutorials repo and a YouTube series
  • —It needs a controller (a Servo 2040 or a Raspberry Pi)
  • —Derived from the MakeYourPet hexapod community design

Can I build this?

Printall structural parts — frame, carapace, legs (coxa/femur/tibia), TPU claws, test stand
Buy18 servos, a Servo 2040 or Raspberry Pi controller, wiring, a battery
Tools3D printer (rigid + TPU), soldering, hex drivers
Skillsassembly patience; follow the video series for wiring and code
Timeseveral weekends
Costband $$ — 18 servos are the main cost; current prices: creator's series
Safetylow-voltage; 18 geared servos — mind fingers during calibration

Build at your own risk. Projects involve tools, electronics and sometimes mains voltage — follow the creator’s safety notes.

KNOWN ISSUES

  • This repo is STL + printing docs only — the control code is in a separate tutorials repo and the video series
  • There's no wiring BOM or STEP CAD here — you'll bring a Servo 2040 or Raspberry Pi and follow the videos
  • Print the claws in TPU for quiet grip; the rest is rigid

How many servos?

18 — three per leg on six legs — with a printed carapace and TPU claws. Some builds add micro-switch feedback in the feet.

Where's the code?

In a separate tutorials repo and the YouTube series. This repo holds the STL parts and printing docs.

Is it a known design?

Yes — it's derived from the popular MakeYourPet hexapod, so there's an active community and shared parts lineage.

What does it cost?

Band $$ — the 18 servos are the main cost. The series covers current parts.

FROM THE COMPAREE TEAM

Eighteen servos, three per leg, all needing calibration before the first step. What's your tolerance for servo-count in a build — where do you tap out?

CompareeTEAM1mo ago

Something we learned tracing the lineage: this isn't a standalone design — it's derived from the MakeYourPet community hexapod, so there's a whole shared parts ecosystem behind it. Also worth knowing that this repo is only the STL and print docs; the control code lives in a separate tutorials repo and the video series. Anyone tried the TPU claws — do they really make it quieter?
