was randomly scrolling through instagram and saw a lady talking about one of these. It's an interesting concept idea for basic cutting on large sheet goods:

kinda looks like the size of a vacuum but drives its self around on a sheet of ply wood etc using these "omni-directional" wheels

not cheap at $4000 USD or 3000 euros (its made in italy)
