Provided is a pet training robot with an improved object discharging function including an object box including an elastic member; first driving means configured to rotate the object box; a base disposed spaced from the object box and including a discharge hole connected to an external space; and control means configured to control the first driving means such that when the object box rotates by the first driving means, the elastic member is in contact with an inner surface of the base and bends to generate an elastic force, when the object box rotates to a vicinity of the discharge hole, an object stored in the object box is discharged, the bent elastic member is unbent to a space of the discharge hole to release the elastic force, and the discharged object is pushed into the discharge hole.

An enhanced hybrid battery elimination circuit, power control system, and method for R/C vehicles is provided. The system may include a power input from a vehicle battery and a converted power output to vehicle electronics. The system may also include an enhanced hybrid battery elimination circuit (BEC) electrically coupled to the power input and providing the converted power output and including a linear regulator and a switching regulator connected in parallel to the linear regulator between the power input and the converted power output. The enhanced hybrid BEC further includes a linear electrical decoupler provided between the linear regulator and the converted power output and a switching electrical decoupler provided between the switching regulator and the converted power output. Wherein the switching regulator and the linear regulator are either electrically coupled or decoupled from the output power and/or the input power based upon a monitored voltage level.

Provided is a pet training fixed type apparatus with an improved object discharging function including a housing having housing hole; an object box including an elastic member; first driving means configured to rotate the object box; a base disposed spaced from the object box and including a discharge hole connected to an external space; and control means configured to control the first driving means such that when the object box rotates by the first driving means, the elastic member is in contact with an inner surface of the base and bends to generate an elastic force, when the object box rotates to a vicinity of the discharge hole, an object stored in the object box is discharged, the bent elastic member is unbent to a space of the discharge hole to release the elastic force, and the discharged object is pushed through the discharge hole and the housing hole into the outside.
