Abstract: The present disclosure is a flex drive with an input configured to be coupled to a motor or drive. The input can have multiple engagement devices removably coupled to the input. The flex drive can have a drive gear portion that is engaged with the engagement devices. A static gear can be partially engaged by the drive gear based on the engagement devices. A first laminate removably coupled to the drive gear, a flex cup removably coupled to the first laminate, and a second laminate removably coupled to the flex cup can allow for the flexibility desired for a flexgear. An output can be removably coupled to the second laminate.

Abstract: A reconfigurable power tool is disclosed, including a tool frame, a motor attached to the tool frame, and a rotatable drive shaft attached to, and driven by, the motor. A tool attachment is configured to be removably attached to the drive shaft and is powered by rotation of the drive shaft. The drive shaft and the tool each include a coupler having a channel and rib surface. The tool attachment is removable attached to the drive shaft by slidably interlocking the channel and rib surface of the drive shaft coupler with the channel and rib surface of the tool attachment coupler in a direction substantially perpendicular to an axis of rotation of the drive shaft. A robotic device utilizing a similar tool attachment system is also disclosed.
