The idea would be to use the vehicle's wings to generate lift and pull up into a new ballistic trajectory, exiting the atmosphere again and giving the vehicle time to cool off between the skips. [6] It was later demonstrated that the heating load during the skips was much higher than initially calculated, and would have melted the spacecraft. [7]
Trajectory optimization is the process of designing a trajectory that minimizes (or maximizes) some measure of performance while satisfying a set of constraints. Generally speaking, trajectory optimization is a technique for computing an open-loop solution to an optimal control problem. It is often used for systems where computing the full ...
A basic motion planning problem is to compute a continuous path that connects a start configuration S and a goal configuration G, while avoiding collision with known obstacles. The robot and obstacle geometry is described in a 2D or 3D workspace , while the motion is represented as a path in (possibly higher-dimensional) configuration space .
Real-Time Path Planning is a term used in robotics that consists of motion planning methods that can adapt to real time changes in the environment. This includes everything from primitive algorithms that stop a robot when it approaches an obstacle to more complex algorithms that continuously takes in information from the surroundings and creates a plan to avoid obstacles.
A tracked articulated vehicle or articulated tracked vehicle (abbreviated as ATV. [ 1 ] but not to be confused with all-terrain vehicle ), is a variation of a continuous track vehicle that consists of two cars, each with their own track, most commonly with an actuated linkage in between.
The track algorithm produces symbology that is displayed on the Plan Position Indicator. Users have a pointing device with several buttons that provides access to the track file through the Plan Position Indicator. The typical pointing device is a track ball, which operates as follows.
Navigation refers to the determination, at a given time, of the vehicle's location and velocity (the "state vector") as well as its attitude. [citation needed] Control refers to the manipulation of the forces, by way of steering controls, thrusters, etc., needed to execute guidance commands while maintaining vehicle stability. [citation needed]
At high speed, the vehicle's dynamic forces are controlled by an internal guidance system, which TransPod calls Veillance Flux. [3] Deviations of the vehicle's trajectory are sensed and tracked by a combination of inertial sensors and optical sensors. [2] TransPod's systems use sense-space processing [11] and real-time computer vision ...
