On 1 October 2026, timed with China’s National Day, MEINONG ROBOT released a four-wheel-drive, four-wheel-steer (4WD4S) universal chassis and published the product parameters for the 250 kg vertical payload (level-ground) specification. The chassis is a general-purpose mobile platform for secondary development and equipment mounting in fields, orchards, and greenhouses. See the Agricultural Robot Chassis product page.
The demo video records workshop manoeuvres: counterclockwise and clockwise in-situ rotation, diagonal forward travel, and 90° lateral movement left and right—suited to turning and side-shifting in tight spaces.
