A self-propelled robot includes a travel cart, a base part provided to an upper part of the travel cart and swivelable on a first rotation axis extending vertically, and a pair of robotic arms coupled to the base part at base-end parts, respectively. Each of the pair of robotic arms has a first link and a second link coupled at a base-end part to a tip-end part of the first link via a joint part. Base-end parts of the pair of first links are coupled to the base part so that the base-end parts are coaxially pivotable on a second rotation axis extending horizontally, and the base-end parts oppose to each other via the base part. The base-end parts of the pair of second links are coupled to side parts of the tip-end parts of the corresponding first links, on the opposing sides of the pair of first links.

A refuse vehicle includes a chassis supporting a plurality of wheels and a vehicle body. The vehicle body defines a receptacle for storing refuse. A lifting system is movable between a first position and a second position offset from the first position. A processing unit is in communication with a first sensor having a first field of view and a second sensor having a second field of view. The processing unit activates the second sensor upon receiving an indication, from the first sensor, that an indicator is present within the first field of view. In some embodiments, the indicator is the presence of a positive object, like a waste container. In other embodiments, the indicator is the omission of an object (e.g., no container is detected) within the field of view.

Embodiments of a solar table mobile transport vehicle capable of carrying multiple solar tables are described. Multiple solar tables may be vertically stacked on a rack. Each solar table may be supported by a pair of cantilevered beams such that the solar table may be unloaded from the rack in an unobstructed manner. The rack may be loaded on a mobile transport vehicle for transportation to a point of installation. Solar tables in the rack may be fetched by the mobile transport vehicle or another installation rover for installation. Such a capability of carrying multiple solar tables increases the installation efficiency of solar tables, especially for large solar farm constructions.

Hauling containers, vehicles having hauling containers, and methods of forming and installing hauling containers are disclosed. In one aspect, a hauling container includes a body defining a storage volume of at least two cubic yards. The body is formed, at least in part, of a polymer material or a non-metallic recyclable material, or both. In another aspect, a vehicle includes a chassis and a hauling container removably mounted to the chassis. The hauling container includes a body defining a storage volume. The body is formed, at least in part, of a polymer material or a non-metallic recyclable material, or both. In yet another aspect, a method includes forming a body of a hauling container. The body defines a storage volume, and is formed, at least in part, of a polymer material or a non-metallic recyclable material, or both. The body is configured to sit on a chassis of a vehicle.
