An articulated tracked vehicle that has a main section, which includes a main frame, and a forward section. The main frame has two sides and a front end, and includes a pair of parallel main tracks. Each main track includes a flexible continuous belt coupled to a corresponding side of the main frame. The forward section includes an elongated arm. One end of the arm is pivotally coupled to the main frame near the forward end of the main frame about a transverse axis that is generally perpendicular to the sides of the main frame. The arm has a length sufficiently long to allow the forward section to extend below the main section in at least some degrees of rotation of the arm, and a length shorter than the length of the main section. The center of mass of the main section is located forward of the rearmost point reached by the end of the arm in its pivoting about the transverse axis. The main section is contained within the volume defined by the main tracks and is symmetrical about a horizontal plane, thereby allowing inverted operation of the robot.

A robotic mobile low-profile transport vehicle is disclosed. The vehicle can comprise a first transport module having a frame assembly, a mobility system, and a propulsion system and a second transport module having a frame assembly and a mobility system. A multi-degree of freedom coupling assemblage can join the first and second transport modules together. The vehicle can include a first platform supported about the frame assembly of the first transport module, and a second platform supported about the frame assembly of the second transport module. Each of the platforms can be configured to receive a load for transport. Additionally, the vehicle can include a control system that can operate to facilitate intra-module communication and coordination to provide a coordinated operating mode of the first and second transport modules and the coupling assemblage about a given terrain.

A self-driving assembly capable of traversing an elevated window. The elevated narrow space window may be present within a confined area, for example, at a wall separating different wide space rooms. The assembly is configured to carry out unique techniques for gaining access to the window from a floor level location. Further, in addition to gaining access unique stabilizing features may be employed both in terms of physical security at an edge defining the window as well as in the form of maintaining balance through unique control over mass transfer when secured at the window.

Interchangeable track system vehicles may include a vehicle chassis having a pair of rear and front drive axles. An interchangeable track system may be configured for interchangeable deployment with vehicle wheels on at least one of the rear and front drive axles, respectively.
