An example system includes a vehicle, a light projector connected to the vehicle, and a control system. The control system is configured to determine a planned operating region for the vehicle within an environment. The control system is also configured to determine that the planned operating region is within a threshold distance of an object within the environment and, in response, determine a caution region to illuminate with the light projector near the object. The control system is further configured to cause the light projector to project an indication of the caution region near the object. The projected indication remains fixed in relation to the object as the vehicle moves toward the planned operating region.

Example implementations may relate to a mobile robotic device that is operable to reorient a distance sensor using an adjustable leveler. According to these implementations, the robotic device may determine a height map indicating surface elevation data for a ground surface on which the robotic device is travelling within an environment. Then, the robotic device may determine a current location of the robotic device relative to the height map. Based on the current location, the robotic device may determine a current spatial orientation of the distance sensor relative to the ground surface. Further, the robotic device may (i) determine an adjusted position of the leveler to which the leveler is movable to cause the distance sensor to spatially reorient from the current spatial orientation to a target spatial orientation and (ii) cause the distance sensor to reorient to the target spatial orientation by moving the leveler to the adjusted position.

Reorienting a distance sensor using an adjustable leveler

Example implementations may relate to a mobile robotic device that is operable to detect pallets using a distance sensor. According to these implementations, the robotic device causes the distance sensor to scan a horizontal coverage plane in an environment of the robotic device. Then, the robotic device receives from the distance sensor, sensor data indicative of the horizontal coverage plane. The robotic device compares the sensor data to a pallet identification signature. Based on the comparison, the robotic device detects a pallet located in the environment. Further, based on the sensor data, the robotic device determines a location and an orientation of the detected pallet.

The present disclosure provides an example motor system. The motor system includes a steering motor with a first rotor positioned within a first stator. The steering motor is configured to rotate the first rotor about a steering axis. The motor system also includes a traction motor including a second stator positioned within a second rotor. The second rotor includes a traction surface defining a wheel. The traction motor is configured to rotate the second rotor about a rolling axis, and the traction motor is positioned within an opening in the first rotor. The motor system also includes an axle positioned coaxial to the second rotor and coupled to the first rotor such that the traction motor rotates about the steering axis as the steering motor rotates the first rotor about the steering axis.

A bolt anchor assembly including an anchor member to be imbedded in concrete, the anchor member having a hollow tubular portion and a base plate, the base plate projecting outwardly from the tubular portion, and a bolt projecting axially through the base plate and tubular portions for attachment to the base of a piece of machinery.

Systems analysis approach to measure and to reconstruct the sound energy flux distribution characteristic of 'live' situations. The present invention relates to a method of measurement of acoustical fields and the functional relationships in audio systems for enhancing the reproduction of sound. The environmental acoustic simulator is a system which generates at least two signals having different combinations of time delays from each of a stereo input signal pair and for deriving therefrom a set of not less than four output channels. At least forty five time delays at nonuniform intervals spanning a time period of not less than two seconds with different frequency equalizations are derived. Diffuse sound fields are created through electronic mixing and by the employment of not less than four loudspeaker groups. The sound fields generated simulate the reverberation typically observed in an auditorium, concert hall or cathedral, without distasteful interaction, or distortions, and provides full dimension and realism to sound by increasing dimension through reflections and emphasizing harmonic relationships nonexistent at recording. This provides greater aesthetic enjoyment of recorded music.
