Tensorfield Agriculture

For image collection on customer sites, and to provide initial weed treatment quotations, a lightweight remote-controlled rover was designed and built for easy two-person maneuverability (named Snappy, as it snaps photographs at a rate of 60-120 frames per second).

Tensorfield developed a system to precisely apply heated vegetable oil to weeds while protecting nearby crops in the seedline.

Thermal micro-dosing is a method of weed control in which extremely small doses of very hot vegetable oil are applied to post-emergent weeds in the most weed-challenged areas such as within the seedline of dense crop stands.

Xiong Chang presented the work of Tensorfield Agriculture at the Embedded Vision Summit 2025, organized by the Edge AI and Vision Alliance.
