Machine with sensor units retained by breakaway couplers
A paving machine includes an implement, an elongated structure, a sensor arrangement, and one or more breakaway couplers. The implement modifies a surface during a movement of the paving machine. The elongated structure is coupled to a side portion of the paving machine and extends along a direction of the movement. The sensor arrangement includes sensor units arranged sequentially along the elongated structure. The breakaway couplers correspondingly normally retain the sensor units to the elongated structure. Each breakaway coupler includes a mounting structure and a retainer unit. The mounting structure is secured to one of the elongated structure or a corresponding sensor unit, while the retainer unit retains the other of the elongated structure or the corresponding sensor unit to the mounting structure by a retention force, which is adjustable.
Autonomous ground surface treatment system and method of operation of such a system
An autonomous ground maintenance system comprising a vehicle comprising a chassis supported upon a ground surface by ground support members, a container supported by the chassis, the container defining a discharge outlet operable to disperse treating material held within the container to a target area of the ground surface, a gate adapted to selectively open and close the discharge outlet, a sensor adapted to identify the target area, and an electronic controller supported by the chassis, the controller being in communication with the sensor and the gate. The controller is adapted to position the chassis at a location proximate the target area such that the discharge outlet is capable of delivering the treating material to the target area and energize the gate to open the discharge outlet.
