The robotic maintenance vehicle (RMV) has a propulsion system, a control system, an electrical power source, a maintenance module, a multi-axis robot, an optical system, and a location translator. The maintenance module is configured to hold different kinds of road maintenance materials. The multi-axis robot is configured to convey the road maintenance material from either the maintenance module to the road, the road to the maintenance module, or both. The optical system and the location translator are configured to be controlled by the control system and operate in conjunction to instruct the multi-axis robot where to pick up and/or place the road maintenance material. The multi-axis robot is configured to be selectively coupled to a distal arm tool.

A self-propelled roadway maintenance machine has an operator's station located on a front portion of the machine's chassis and including a forward-facing operator's seat. A driven implement, such as a crack routing cutter drum for routing cracks in a roadway surface, is mounted on the front portion of the chassis in a location that can be monitored by a forward-facing operator while controlling machine steering and propulsion. The implement may be removably mounted on the chassis by a quick-connect coupling. If the implement comprises a crack routing cutter drum, a plurality of peripherally spaced cutter wheel assemblies may be mounted between disks of the cutter drum, each cutter wheel assembly including a pin and first and second bushings that support the pin on the disks and that are removably inserted into respective bores in the disks. Machine steering and propulsion and implement operation may all be effected hydraulically.

Method for automatically repairing road potholes includes: irradiating and receiving laser to and from potholes, taking image of potholes and storing image information, calculating distance to potholes, calculating surface area of potholes based on distance to potholes and image information, transmitting image information and surface area information to vehicle device, storing surface area information and image information, calculating the amount of asphalt concrete based on surface area information, heating work area of potholes, cutting work area of potholes, crushing asphalt, sucking in crushed asphalt and storing it in residue storage tank, removing scraps of potholes, supplying asphalt concrete from asphalt concrete storage tank to potholes, receiving weight information from digital gauge at the bottom of the asphalt concrete storage tank to calculate the amount of asphalt concrete, flattening asphalt concrete on the potholes, and displaying image after completion of laying of asphalt concrete on the potholes.

The present disclosure provides various aspects for mobile and automated processing utilizing additive manufacturing and the methods for their utilization. In some examples, the mobile additive manufacturing apparatus may perform surface treatments that support the building of walls. Other examples may involve the support of creating and repairing advanced roadways.

The present disclosure provides various aspects for mobile and automated processing utilizing additive manufacturing and the methods for their utilization and for making material dispensing element arrays for use of the additive manufacturing device.

A microtrenching system having a vacuum hose supported between a vacuum truck and a microtrencher so that the vacuum hose does not contact the roadway surface while cutting the microtrench. A method of using the microtrenching system to cut a microtrench in a roadway and vacuuming spoil from the roadway and microtrench through the supported vacuum hose into a spoil container on the vacuum truck.

A method, system, and computer program product for repairing cracks in structures by automatically transferring filler materials along a magnetic force pathway inside the structures. The method may include identifying a crack in a structure. The method may include analyzing dimensions and positions of the crack. The method may include identifying an array of magnetic coils near the crack, wherein the array of magnetic coils can create a magnetic path to the crack. The method may include determining an appropriate filler material reservoir connected with the structure based on the array of magnetic coils and the crack in the structure. The method may include transmitting instructions to release a quantity of the filler material mixture from the appropriate filler material reservoir connected with the structure for each of the one or more cracks.
