Crawler One — Tracked Tank Robot Kit

Crawler One is a 4-track robot tank you assemble, then drive from your phone, tablet or browser — over your home WiFi or across the planet. Live HD video, tilt-to-steer, voice commands, and a customizable on-screen control panel. Powered by a real Raspberry Pi, so you can hack, extend and grow with it.

Choose your kit:

• Chassis Kit — All chassis parts: track frames, drive cogs, 64 track links, shells, top & floor covers, Pi/Pico cases. No electronics. Bring your own Pi, motors, etc. Intermediate · soldering required.

• Builder Kit — Chassis Kit + 4× drive motors, camera tilt servo, motor controller, power module, illuminated master switch, wiring harness, and all hardware. Drop in any Raspberry Pi (Zero 2 W, 3, 4 or 5) and you're driving. Intermediate · soldering required.

• Complete Kit — Same as Builder, but we do the soldering and the Pi setup for you. Open the box, snap on the tracks, scan the QR code, drive. Beginner · no tools needed.

What you can do with it:

• Drive from anywhere — phone, tablet or browser, anywhere with internet

• Live HD video stream — see what the robot sees, low-latency WebRTC

• Tilt to steer — tilt your phone, the tracks follow

• Tilt the camera with an on-screen slider

• Voice control — talk to your robot, AI does the rest

• Custom controls — ask the AI to build buttons, sliders, joysticks for any add-on you bolt on

• Built around a real Raspberry Pi — yours to hack, extend, upgrade

What you'll need (not in the kit):

• Soldering iron, multimeter, screwdriver (Chassis & Builder kits)

• 2S Li-ion 7.4 V battery with XT30 (any standard 2S hobby pack with an XT30 plug — your local RC / hobby shop)

• microSD card (8 GB+) for the Pi

• Raspberry Pi (only for Chassis Kit — included in the others)

Build time:

• Chassis & Builder Kits: ~3–4 hours assembly

• Complete Kit: ~10 minutes unboxing

Includes lifetime firmware updates, free iOS & Android app, browser dashboard, illustrated online build manual, and friendly support if you get stuck.
