This is a full-body photograph of a bipedal robot, designed to walk on two legs. The robot is constructed from multiple metallic and mechanical parts, with visible wires and circuit boards that suggest its complex internal workings. The legs are particularly detailed, featuring multiple joints and actuators, and its feet are encased in blue, shoe-like coverings. The robot has "IIT" logos on the upper part of each leg, indicating its likely affiliation with the Indian Institute of Technology.

This picture shows the electrical diagram of a Sharp brand two-door refrigerator. The main components include the compressor, condenser, filter, evaporator, and heater for the automatic defrosting system.

Electric current flows from the source (L and N) through the thermostat, which controls temperature. When temperature rises, the thermostat activates the compressor and fan to cool.

The automatic defrost system works with a timer (timer), bimetal defrost, and heater, which melts the ice from the evaporator. Thermofuse acts as protection against overheating. The lamp turns on when the door is opened, and the capillary tube regulates the flow of refrigerant from the condenser to the evaporator.
