Abstract: Methods of reducing calculation time for inverse kinematics for a robotic arm are presented. An analytical solver is used based on design values for a robot type to generate an analytical solution of joint parameters to achieve a desired location of a tool center point of the robot type, wherein the robotic arm has the robot type. The analytical solution of joint parameters is provided as a seed value to a numerical solver for the robotic arm of the robot type. A numerical solution is determined using the numerical solver and the seed value, the numerical solution comprising joint parameters for the robotic arm to achieve the desired location of a tool center point of the robotic arm.

Abstract: A robotic drill system and a method of drilling with a robotic drill system. This includes inserting a tool head of the robotic drill within a hole of a drill template along an initial insertion trajectory with a robotic manipulator arm that is moved by at least one robotic actuator for causing robotic insertion of the tool head. In response to sensing binding of the tool head to a wall of the hole while inserting the tool head along the initial insertion trajectory, the disclosure includes stopping robotic insertion of the tool head and activating a self-centering device of the tool head to reorient the tool head to a corrected alignment of the tool head axis relative to the hole. The self-centering device may include an expandable collet.

Abstract: A system for and method of generating an API or an API template for use with a map service. The API, e.g., URL when invoked in a WMS server or WMTS server, causes generating a metadata for a set of one or more areas of interest (AOIs) and one or more date ranges. The metadata provides access to a dataset of surveys via getmap or gettile requests. The API is dynamic in that the effect of the API (the metadata generated) is automatically updated whenever there has been a new survey added in the set of AOIs and date ranges. The API template is for a TMS service, and when populated, provides for causing any tiled map in the set of AOIs and date ranges to be displayed.
