Robot Vacuum Cleaner - Full Product Assembly with Drive, Brush and Lidar Systems 3D Model (Concept)

Concept 3D model of a robot vacuum cleaner, modelled as a full product assembly of roughly 70 solids in FreeCAD. This is a self-initiated portfolio piece, not a manufactured product. What is modelled: - Round chassis with roller-brush opening, wheel wells, caster hole and rear exhaust slots, plus a top cover, front bumper segment and dustbin access lid - Two drive wheels, each with tire, hub, axle, wheel motor, suspension arm and damper, plus a front caster - Cleaning system: main roller brush with 8 bristle fins and brush frame, side brush with three arms and bristle tufts - Dustbin with lid and filter, suction motor with mount and 8-blade fan impeller - Electronics: battery pack with 4 cells, circuit board on 4 standoffs, lidar turret with sensor window, 4 cliff sensors, charging contacts, 3 buttons and 6 screws Views included: assembled render, top and front views, cutaway with the cover removed, a top view of the internals, and an exploded view. Files: STEP (opens in SolidWorks, Fusion 360, Inventor, Onshape and most CAD tools), editable FreeCAD file, STL and PNG renders. I do 3D mechanical and product design, DFM-minded part modelling, multi-part assemblies and exploded views, and process-equipment models (pumps, heat exchangers, vessels, skids). Message me with your sketches or specs and I can model your product and deliver STEP files and PDF drawings.
