An agricultural robot includes a machine body, a wheeled traveling device to support the machine body such that the machine body is capable of traveling, the traveling device including at least three wheels, a manipulator including an arm and a robot hand, the arm being attached to the machine body, the robot hand being attached to the arm and capable of holding an object, and a balance controller to control positions of the at least three wheels, respectively, to achieve a balance between the machine body and the manipulator.

Agricultural robot

An agricultural robot includes a traveling body, a working unit on the traveling body to do work relating to a crop, an optical sensor on the traveling body, and a crop estimator to perform estimation of the crop based on sensor data obtained by the optical sensor. The crop estimator includes a data extractor to designate the crop to be subjected to the estimation based on the sensor data and extract, as partial data, a portion of the sensor data that corresponds to the designated crop, and an estimator to perform the estimation of the crop based on a surface condition of the crop obtained from the partial data extracted by the data extractor.

A fuel meter ( ) of a fuel injection pump is made movable for fuel metering through a governor lever ( ). A swing lever ( ) has a power input point (J) which engages with a boost actuator ( ). If the boost actuator ( ) operates in response to a delayed rise of a supercharged pressure (P), a power output point (K) of the swing lever ( ) inhibits the fuel meter ( ) from moving for fuel increase. A governor lever ( ) is connectably and separably opposed to the fuel meter ( ) from a fuel increase side and a start spring ( ) urges the fuel meter ( ) toward a starting fuel increase side. The swing lever ( ) has a pivot axis (Q) displaceable by an actuator ( ). When making a cold start, the actuator ( ) does not operate to thereby confine the fuel meter ( ) to a starting fuel increase position by the power output point (K) positioned on a fuel increase side. When making a warm start, the power output point (K) positioned on a fuel decrease side confines the fuel meter ( ) to a starting fuel decrease position (Ls).
