VACUUM CLEANERS / COMPACT VACUUM

SweepA tidy starting point for home robotics.

Sweep combines a circular chassis, differential drive, a brush layout and range sensing. Explore the packaging and control of a compact vacuum concept with an ESP32-C3 and a working avoidance demonstration.

YOUR FIRST THREE EXPERIMENTS

Build understanding.
One change at a time.

Use the starting assembly to ask better questions about your design. Save a copy, change a parameter and compare what happens.

Inspect the design

Run the range-based avoidance controller around the obstacle scene.

Try a change

Inspect wheel, brush and fan placement within the circular footprint.

Compare and learn

Compare power and mass when substituting components or adjusting the load.
