1. An agricultural treatment system, comprising:
a first motor assembly including a first motor and a first rotational output component coupled with the first motor, wherein the first motor is configured to rotate about a first motor rotational axis;
a second motor assembly including a second motor and a second rotational output component coupled with the second motor, wherein the second motor is configured to rotate about a second motor rotational axis, wherein the first motor rotational axis is a different axis than the second motor rotational axis;
a first linkage assembly coupled to the first rotational output component of the first motor assembly, wherein the first linkage assembly is configured to move in a first direction in response to rotation about the first motor rotational axis by the first motor;
a second linkage assembly coupled to the second rotational output component of the second motor assembly, wherein the second linkage assembly is configured to move in a second direction in response to rotation about the second motor rotational axis by the second motor; and
a treatment head assembly coupled to the first linkage assembly and coupled to the second linkage assembly, at least a portion of the treatment head assembly being configured to rotate about a first treatment head assembly rotational axis in response to movement of the first linkage assembly in the first direction, and at least a portion of the treatment head assembly being configured to rotate about a second treatment head assembly rotational axis in response to movement of the second linkage assembly in the second direction, wherein the treatment head assembly includes:
a treatment head,
a first fluid port coupled to the treatment head, wherein the first fluid port is configured to deliver a fluid into the treatment head,
one or more spraying tips coupled to the treatment head and configured to spray the fluid onto an agricultural target object, and
a fluid regulator coupled to and configured to interact with the treatment head, wherein the fluid regulator is configured to deliver the fluid from the first fluid port to the one or more spraying tips when the fluid regulator is actuated from a first position to a second position,
a first treatment head assembly frame or ring coupled to and situated about the treatment head assembly, wherein the treatment head assembly frame or ring is coupled to the first linkage assembly and is configured to rotate about the first treatment head assembly rotational axis in response to movement of the first linkage assembly in the first direction, and wherein the first treatment head assembly frame or ring is coupled to a first bracket and a second bracket, wherein the first treatment head assembly frame or ring is rotatable between the first bracket and the second bracket; and
a second treatment head assembly frame or ring coupled to the first treatment head assembly frame or ring and is configured to rotate about the second treatment head assembly rotational axis in response to movement of the second linkage assembly in the second direction.
