Looks really cool, does anyone want to speculate on how it works? They say they have four sensors in the broom head? what do you think they are? pressure sensors maybe? do you think they have an accelerometer in addition to these sensors?

Given that he wanted to measure stroke rate and force, it stands to reason that the accelerometer handles the stroke rate and the four sensors measure the force.


I'd imagine that (like the bathroom scale that they referenced, even if they're using different hardware) they have four 3-axis force sensors which connect the sweeping head to the broom, letting them calculate the forces while allowing for different angles.


I think it was a mistranscription, and should read as "force sensors" (a.k.a. load cells) rather than "four sensors."
