There is disclosed an improved pile point for foundation piles such as the H-beam pile. The point provides an improved biting edge which eliminates skidding and slipping on inclined rock stratum or when the pile is used as a batter pile. The point includes a web and a pair of flanges positioned at the ends of the web and perpendicular thereto, the flanges including, typically, angled side portions to which are fixedly secured teeth-like protrusions. The latter provide a biting edge which grab hold of the supporting stratum, even when it is at a sharply inclined angle, to eliminate slipping and skidding on such surfaces. Such teeth-like protrusions are provided on a flattened portion of the web and flange affording additional biting edges. The latter protrusions can be arranged such that the point can provide improved biting regardless of its orientation relative to the rock stratum.

A pile joiner is disclosed for connecting together the ends of concrete piles which joiner includes a socket member and a mating member one of which is on the end of one pile and the other is on the end of the pile to be connected therewith. Each of these two members has a base plate with a central hole therethrough and a tubular element secured to each base plate and extending at right angles thereto. One tubular element is a socket element and the other is a mating element which is received within the socket element. The socket element and the mating element have at least a first sleeve means which includes a sleeve hole or holes through a wall or walls of each element and in alignment when the members are assembled together, an outer sleeve for each sleeve hole of the socket element extending outwardly and an inner sleeve for the sleeve hole or holes of the mating element extending inwardly or between sleeve holes in opposite walls thereof. When the two members are assembled together with their base plates in contact, the first sleeve means of each member or element are in alignment and receive a lock bar to retain the two members and their piles together against separation. Preferably the tubular socket element and the tubular mating element have a second sleeve means similar to the first which are in alignment when the two members are assembled together and preferably angularly located with respect to the first sleeve means.

Various embodiments include devices and methods for navigating a robotic vehicle within an environment. In various embodiments, a first image frame is captured using a first exposure setting and a second image frame is captured using a second exposure setting. A plurality of points may be identified from the first image frame and the second image frame. A first visual tracker may be assigned to a first set of the plurality of points and a second visual tracker may be assigned to a second set of the plurality of points. Navigational data may be generated based on results of the first visual tracker and the second visual tracker. The robotic vehicle may be controlled to navigate within the environment using the navigation data.
