120mm Robot Body

An open-source 3D-printed body for Maker’s Pet MINI robot. Compatible with Maker’s Pet BDC-30P board. Requires assembly.

Recommended Use: build a complete LiDAR-enabled DIY Arduino/ROS2 robot capable of room mapping, automatic navigation using the map. All Maker’s Pet robots are expected to be app-capable in 2025 H2.

• Purchase this robot body or 3D-print it yourself at no charge
• Add two 12V N20 encoder motors, two motor precision clamps and two 43mm wheels
• Add a Maker’s Pet BDC-30P controller/driver board with an ESP32 DOIT DevKit v1 compatible board
• Add a LiDAR
  • LDROBOT LD14P (recommended)
  • Mounts available for YDLIDAR X2L, YDLIDAR SCL
  • Other similar-sized LiDAR models might work as well using customized LiDAR posts and skirts.

Technical Specifications:

• 120mm base diameter
• Height as measured from the floor to top of LiDAR
  • Approx. 94.25mm for YDLIDAR X2L
  • Approx. 86.15mm for LDROBOT LD14P
  • Approx. 85.9mm for YDLIDAR SCL
• 3D printed using PETG plastic
  • There may be stringing left over after 3D printing. The stringing does not affect the functionality.
• Weight approx. 50g including screws

3D Printing Instructions:

• I recommend using PETG. PLA is also acceptable unless your robot is exposed to the sun.
• Set Seam Position to Random in your slicer when printing the caster wheel. Without this setting the caster can make a rhythmic knocking sound when rolling over hard floors.
