1. A system for manufacturing a composite wood product, comprising:
a filler material applicator configured to apply a filler material to a plurality of wood elements;
a roller element configured to apply a compression force to the plurality of wood elements, wherein the roller element comprises a spherical body and includes a surface that applies the compression force to the plurality of wood elements;
an ultrasound transducer configured to deliver ultrasound energy to the plurality of wood elements via the roller element to bond the plurality of wood elements into a composite wood product, wherein the ultrasound energy has a frequency within a frequency range of 10 kHz-20 MHz; and
a motion controller configured to control one or more movements of the ultrasound transducer and the roller element.
