The Robooter X40 folds itself: one button, no bending down, no catches. It runs 2 x 200 W motors on rear wheel drive.
Ten inch omni directional front wheels and pneumatic rear tyres handle uneven ground, a 2.4 inch obstacle and a 4 inch ditch, confirm the incline limit in the supplied manual, and an IPX4 rating means light rain is not a problem. It carries 265 lb, which is lower than the rest of the range, and it weighs 92 lb without the battery, so plan transport rather than lifting.
