Original byitl build

Everyspot 2026

4WD skid-steer yard-watering rover. Pi 5 + OAK-D Lite stereo vision + GPS + IMU navigates beds; a 2-axis MG996R-gimballed sprinkler head aims a hose-fed stream where the planner says to water.

Heads up: samples are here to be fun and spark ideas. They may be incomplete or unverified — use as a starting point, not a finished product.

Built for real

Photos and video from the actual prototype during development — not the render.

First-round prototype: a Raspberry Pi driving a kids' car chassis with a rotating sprinkler head bolted on top.
Second-round prototype: fully 3D-printed chassis with treaded wheels and the sprinkler head integrated.

byitl's 2026 yard-watering rover. Same premise as earlier Everyspot revisions — autonomous bot waters the bed, never the concrete, never the same spot twice — but the 2026 build cleans up the chassis, upgrades the sensor stack, and gives the sprinkler a real two-axis gimbal so the bot can aim from one position.

The change

  • Closed chassis (240 × 170 × 95 mm) with a removable top hatch on M3 thumbscrews. Single printable enclosure that fits the Bambu P1S plate, no exposed wiring on the outside.
  • 80 mm rubber wheels on JGA25-371 metal-gear motors — motors mount INSIDE the chassis, only the wheel hubs and motor shafts pass through bored side walls.
  • OAK-D Lite stereo depth + AI behind a lens-cluster cutout on the front face. Sees the yard, distinguishes bed from sidewalk.
  • u-blox NEO-M9N GNSS puck on the roof through a hatch bore so it always sees sky; BNO055 IMU lives inside on the floor for heading + tilt.
  • 2-axis MG996R gimbal sprinkler on the roof — pan + tilt independent, nozzle aims where the planner directs.
  • GHT quick-disconnect on the rear so it docks to a standard garden hose.
  • TPU side skirts wrap the lower edges so debris stays out of the wheel wells.

What's in the pack

Print-ready STL for every printed part (chassis, top hatch, four wheels, hose block, gimbal yoke, two TPU skirts), editable STEP, six angle renders + interactive WebGL viewer, a complete BOM (Pi 5 + OAK-D + NEO-M9N + BNO055 + JGA25-371 + MG996R + 4S 21700 + LM2596 + GHT brass quick-disconnect + TPU skirt filament), and assembly instructions.
