  "textContent": "The invention discloses a universal wheel including a support base, the support base including a top portion connected with a steering assembly that enables 360° rotation of the universal wheel, and a rolling assembly, the rolling assembly including an axle and a roller rotatably connected to the axle. A coordinate system is constructed with a center of the roller as an origin, a traveling direction of the roller as a negative direction of an abscissa, and a direction perpendicular to the abscissa and extending upward as a positive direction of an ordinate, the support base has a chute located in a first quadrant, and the axle is slidably connected to the chute along a radial direction of the roller. This apparatus has good shock absorbing performance and a strong obstacle-crossing ability.",
