Aigen announced Element Gen 2 X4 in a 18 September 2026 new-product item carried by Sugar Producer Magazine (Redmond, WA). The X4 is the four-arm configuration of Aigen’s second-generation Element robot: four independently operating arms remove weeds at the root, in the row and between rows, up to 12-inch foliage diameter. Two- and three-arm (X2, X3) configurations remain available.
Sugar Producer reports the robots run entirely on solar with solar-charged battery backup and navigate as a coordinated fleet using Aigen’s custom edge AI. Fleets are available to growers for the 2027 season. Co-founder and CEO Kenny Lee said Element fleets bring “the precision of a hand crew at the scale of a sprayer, fully autonomously and fully solar-powered.” Co-founder and CTO Richard Wurden said adding four arms while staying on a limited solar power budget was a hardware, software, and power-usage challenge.
The same article says Aigen has built more than 100 robots and logged more than 15,000 autonomous hours across generations; Element is designed for 10,000 active operating hours or 8 years, with a two-year bumper-to-bumper warranty (motors included regardless of hours; wear and consumables excluded). Element Gen 2 X4 records weed density going into a field and removal coming out.
Aigen’s official agriculture page describes the Element platform (not X4 by name): 100% solar-powered with a 350 W panel and onboard storage battery; AWD, IP65, foam-filled wheels; Strike and Sweep modes; crew packs of 5, 10, or 20+ robots; 200 acres/season per 5-robot crew; designed, engineered, and assembled in the USA.
