Abstract: Disclosed is a robot apparatus with a capable and highly maneuverable drive system incorporating two differential swerve drive pods. The robot apparatus further includes a claw mechanism for grasping an object, a passthrough mechanism for moving the object horizontally and a lift mechanism for moving the object vertically. The robot apparatus allows for rapid manipulation and movement of objects such as cones.

Abstract: A method includes assembling a sensor subassembly that includes a sensor, a sensor mount, a collar, a sharp, and a sensor cap. The method includes loading a sensor in a sensor mount; dispensing adhesive into a mount channel of the sensor mount; clamping a collar to the sensor mount; and curing the adhesive to fix the collar to the sensor mount. The method can also include inserting a sharp into the sensor mount over the sensor an attaching a sensor cap to the sensor and sensor sharp to provide a sealed sensor subassembly. Methods of assembling an on-body sensor puck assembly and an applicator assembly, and a sensor including a tail, a flag, and a neck that interconnects the tail and the flag and methods of configuring a sensor are also disclosed.
