    Abstract: Disclosed herein is a compliant joint that is movable in three degrees of freedom (DOF), as well as systems including the compliant joint, and a process for assembling the compliant joint. The compliant joint may comprise an elongate arm, a ball joint, and a carrier. The ball joint is configured to couple to the carrier, and the elongate arm is configured to couple to the ball joint. The ball joint may have a cross section that is ellipsoidal, an outer surface that is convex, and a first hole. The carrier may comprise a second hole that is ellipsoidal, and an inner surface that is concave. The elongate arm, when disposed within the first hole, is movable axially through the first hole, and the ball joint, when disposed within the second hole, is movable with at least one of pitch rotation or yaw rotation.

    Abstract: Techniques for managing device interaction between components of an inventory management system are described herein. User input associated with an operational state of the user device may be received at the user device and the user device may begin operating in a particular operational state. While operating in this state, the user device may transmit a wireless signal having a predetermined frequency. A mobile drive unit of the system, upon receipt of the wireless signal, may slow or stop. Operational state information may be transmitted to other components of the inventory management system indicating that the wireless signal is being transmitted and/or that the user device is operating in a particular operational state and a fault detection process may commence. The user device may provide an indication (e.g., via visual, audible, and/or haptic feedback devices) that the user device is operating in the particular operational state.

    Abstract: Embodiments herein described a replaceable recharge cartridge that is coupled between a charge port of a robot and a charging station. Instead of mating the charging station directly to the charge port in the robot, the recharge cartridge can instead be inserted into the charge port and serves as an interface between the robot and the charging station. As such, the wear and tear occurs on the recharge cartridge rather than the charge port of the robot. In one embodiment, the recharge cartridge is magnetically attached to the charge port for easy installation and removal. The recharge cartridge includes a ferrous slug that is attracted to a permanent magnetic disposed in the charge port. The magnetic attraction between the permanent magnetic and the ferrous slug aligns and connects the recharge cartridge to the charge port.
