Overview

300 mm 3D-printable differential-drive pet robot with an ESP32, BLDC gear motors, a 360-degree LiDAR and a phone or tablet head, run through the shared Kaia.ai ROS 2 stack; pet character and skills are upstream work in progress. [S001] [S008] [S015]

Snoopy is a round, two-wheel differential-drive pet robot that maps rooms and navigates with ROS 2. An ESP32 runs the onboard firmware, a 360-degree LiDAR supplies scans, and a phone or 7-inch tablet serves as the head display and camera. SLAM, Nav2 and Gazebo run on a separate PC; the platform README offers Docker on Windows or Linux and Ubuntu 24.04, untested here with this snapshot. The maker lists character and skill programming as work in progress, so the documented workflow is mapping and navigation rather than pet behaviour. [S001] [S009] [S015]

Assembly and use

What the Snoopy repository contains

The pinned makerspet_snoopy repository is a ROS 2 description package: a URDF robot model plus commands that run simulation, Cartographer mapping and navigation through the shared Kaia.ai packages. Its URDF gives a 300 mm base, 67 mm wheels and about 0.263 m between wheels, and its telemetry file defaults to a YDLIDAR X4. The README links the STL, 3MF, firmware and KiCad files in separate repositories. [S001] [S004] [S005] [S006] [S007]

Printable parts live in makerspet/3d_models, which lists Snoopy plates, BLDC motor brackets, a YDLIDAR mount, optional bumper and cliff-sensor parts, and a Fusion 360 archive. That repository exceeded the catalog's 150 MiB archive limit, so the file list was preserved but no geometry was opened. The maker page says the parts need a 300 × 300 mm or larger print bed. The README's assembly video is labeled for the Loki and Fido models, and no Snoopy-specific written assembly guide was identified; the video was not reviewed, so plan to use the linked support forum for assembly questions. [S001] [S009] [S010]

Firmware and electronics to reconcile

The README links the shared kaiaai/firmware ESP32 code, which the Kaia.ai platform README describes as the firmware for its robots. The firmware README says it supports ESC-style BLDC motors with PWM, direction and FG pins. However, the board configurations shipped in the pinned snapshot name Mini-family boards and a makerspet_vac BLDC board, not Snoopy. A builder must write or adapt a configuration for their own board, motors and LiDAR. [S001] [S012] [S014] [S015]

The README's KiCad link now resolves to makerspet/store. That snapshot holds schematic PDFs, STEP files and one Gerber archive for named boards such as BRK-30P, BDC-30P and an LDS02RR adapter, none labeled for Snoopy, and no editable KiCad project. The 2023 Snoopy page says a brushless ESP32 board was still planned for the store. A matched Snoopy driver-board design was not identified in the inspected sources. [S009] [S016] [S017]

Cost scope

The September 2023 BOM page lists an ESP32, regulator, battery, YDLIDAR X4, two CHR-GM25-BLDC2418 motors, tires, a breakout PCB and 1 kg of filament, totalling $199.60. The phone or tablet, PC and printer are bring-your-own at $0, and optional cliff and bumper sensors cost about $1 each extra. The listed quantities and unit prices sum to $196.40, so the stated total does not reproduce exactly. Treat it as a dated parts estimate, not a current quote. [S008]

Licenses and unknowns

The description package and CAD repository carry Apache-2.0 license files. The shared firmware's root license is also Apache-2.0, but bundled AsyncTCP and ESPAsyncWebSrv carry LGPL-3.0 files and PID_Timed a GPL-3.0 file. Check those terms before redistributing binaries. No firmware was compiled, no parts were printed and no robot was built or tested for this profile. [S003] [S011] [S013]

Source files and licenses

Printable CAD, shared firmware and the ROS 2 description are public under Apache-2.0 root licenses; matched electronics source, a Snoopy-specific firmware configuration and a current budget remain unresolved.

Layer	Availability / license
mechanical design	available · Apache-2.0 STL, 3MF and a Fusion 360 archive (Snoopy v126.f3z) are listed at the pinned commit. The repository archive exceeded the 150 MiB intake limit, so files were listed, not preserved or opened. Root Apache-2.0 as declared; purchased motors, LiDAR and battery are not covered. [S010] [S011]
electronics	not found · License not fully assessed README-linked makerspet/pcb now resolves to makerspet/store, whose pinned snapshot holds schematic PDFs, STEP models and one Gerber archive for other boards, without an editable KiCad project. The 2023 Snoopy page says a brushless ESP32 board was planned; its design source was not identified. [S001] [S009] [S016] [S017]
firmware	available · Apache-2.0 (root); bundled LGPL-3.0 and GPL-3.0 libraries Shared platform firmware. Root Apache-2.0, but bundled AsyncTCP and ESPAsyncWebSrv carry LGPL-3.0 files and PID_Timed a GPL-3.0 file. Pinned board configurations name Mini-family boards and a makerspet_vac BLDC board, none for Snoopy. [S012] [S013] [S014]
software	available · Apache-2.0 ROS 2 description package (URDF, SDF meshes, Nav2/Cartographer configuration). Runtime packages live in separate Kaia.ai repositories whose licenses were not individually reviewed. [S001] [S003] [S004] [S015]
documentation	available · Apache-2.0 Repository README under the root license. Maker's Pet blog pages and linked videos show no separate license in the inspected text; videos were not reviewed. [S001] [S003] [S008] [S009]
