Abstract
There are provided a foot structure for a robot and a robot that suffer small restrictions and are capable of detecting reactive forces from a walking surface with a simple structure. A foot includes an elastic member attached to a sole member and elastically supporting an instep member, a first range sensor disposed on one of the instep member and the sole member, for measuring the distance up to the other of the instep member and the sole member, and a second range sensor disposed on the one of the instep member and the sole member at a position different from the first range sensor, for measuring the distance up to the other of the instep member and the sole member.

A foot structure provided on a lower end of a leg of a robot, the foot structure comprising:
- an instep member joined to the leg;
- a sole member disposed beneath the instep member, and configured to contact a walking surface;
- an elastic member attached to the sole member and elastically supporting the instep member;
- a first range sensor disposed on one of the instep member or the sole member, the first range sensor configured to measure a distance to the other of the instep member or the sole member;
- and
- a second range sensor disposed on the one of the instep member or the sole member at a position different from the first range sensor, the second range sensor configured to measure a distance to the other of the instep member or the sole member.
