Abstract: A power tool includes a housing, a rechargeable battery pack coupled to the housing, and a motor supported by the housing. The motor includes a stator assembly having a stator frame with an opening extending therethrough and a plurality of coil windings configured to be selectively powered by the rechargeable battery pack. The coil windings are positioned adjacent the opening of the stator frame. The motor further includes a rotor assembly disposed within the stator assembly and configured to rotate as the coil windings are powered by the rechargeable battery pack. Moreover, the power tool includes an output drive assembly supported by the housing. The output drive assembly extends through the opening of the stator frame to be operably coupled to the rotor assembly.

Abstract: A robot competition field assembly including field end sections, a field mid-section, and a field alignment system. The field end sections and the field mid-section include panels and sidewalls. The field alignment system is configured to align the panels so that there is a smooth transition between each of the playing surfaces of the field end sections and field mid-section.

Abstract: A system including a power tool and a battery pack. The system includes a power tool including a housing. The housing includes a battery pack interface that includes a first battery pack terminal and a first retaining element. The power tool also includes an electric motor and a controller. The electric motor includes an inner stator, an outer rotor, and a fan.
