Abstract: An intelligent foot of a humanoid robot, which enables the robot to safely walk in balance even on the irregular ground, is disclosed. The walking robot's foot includes a backpart unit with a leg which is rotatably installed at the center thereof, and a forepart unit which is rotatably connected to the front of the backpart unit by a foot part connector, wherein 6-axis force/moment sensors are installed on the bottom of the backpart unit and the bottom of the forepart unit, respectively. Further, walking robot's foot includes a backpart unit with a leg which is rotatably installed at the center thereof, and at least two toes which are rotatably connected to the front of the backpart unit by foot part connectors, wherein a 6-axis force/moment sensor is installed on the bottom of the backpart unit, and short shaft sensors are installed on the bottom of the toes.

Abstract: An egg roaster for roasting eggs using an electric heater is disclosed. An internal air circulator is provided in an insulation chamber in which is mounted guide shelves for egg loading and forcing circulation and diffusion of an internal air to evenly roast the eggs. An air discharge unit forceably discharges the internal air to prevent egg burning and dewing from moisturel. An external air influx member administers the supply of external air.

Abstract: A 6-component load cell used for measuring triaxial force and moment components is disclosed. The load cell has a sensing unit and an external case. In the sensing unit, upper and lower rings individually have a plurality of connectors and arcuate thick parts. The sensing unit also has a cross beam, consisting of horizontal and vertical parts crossing at right angles with a plurality of vertical and transverse binocular openings being formed on the two parts. A radial slit is formed at each corner of the junction of the cross beam. A plurality of strain gauges are attached to the cross beam. The external case has upper and lower parts, individually having a plurality of arcuate openings corresponding to the arcuate thick parts of the sensing unit. The lower part of the case also has a plurality of cord lead openings at the side wall.
