What are the methods of planning the motions of a robot?
The motion planning problem is typically solved using algorithms that search the robot's configuration space, which is the set of all possible positions and orientations that the robot can reach. The configuration space is often high dimensional, making the search for a feasible trajectory a challenging problem..
What is computational motion planning?
Motion planning, also path planning (also known as the navigation problem or the piano mover's problem) is a computational problem to find a sequence of valid configurations that moves the object from the source to destination. The term is used in computational geometry, computer animation, robotics and computer games..
What is motion planning in robotics?
Motion planning is a term used in robotics for the process of breaking down a desired movement task into discrete motions that satisfy movement constraints and possibly optimize some aspect of the movement..
What is motion programming in robotics?
Motion Programming in Robotics Linear, joint, and circular motion commands allow the programmer to choose the most appropriate path to accomplish a task..
Why is motion planning important in robotics?
Motion planning is a term used in robotics for the process of breaking down a desired movement task into discrete motions that satisfy movement constraints and possibly optimize some aspect of the movement. For example, consider a mobile robot navigating inside a building to a distant waypoint..
Why path planning is required for a robotic system?
Many problems in various fields are solved by proposing path planning. It has been applied in guiding the robot to reach a particular objective from very simple trajectory planning to the selection of a suitable sequence of action..
Description. An RRT grows a tree rooted at the starting configuration by using random samples from the search space. As each sample is drawn, a connection is attempted between it and the nearest state in the tree.

Motion Programming in Robotics Linear, joint, and circular motion commands allow the programmer to choose the most appropriate path to accomplish a task.
The main reason that we use motion planners is that it speeds up the programming process when the robot is in a complex environment.
Another approach to motion planning involves constructing artificial potential fields which are designed to attract the robot to the desired goal configuration
In this course we will consider the problem of how a robot decides what to do to achieve its goals. This problem is often referred to as Motion Planning and it
In robotics and motion planning, kinodynamic planning is a class of problems for which velocity, acceleration, and force/torque bounds must be satisfied, together with kinematic constraints such as avoiding obstacles. The term was coined by Bruce Donald, Pat Xavier, John Canny, and John Reif. Donald et al. developed the first polynomial-time approximation schemes (PTAS) for the problem. By providing a provably polynomial-time ε-approximation algorithm, they resolved a long-standing open problem in optimal control. Their first paper considered time-optimal control of a point mass under Newtonian dynamics, amidst polygonal (2D) or polyhedral (3D) obstacles, subject to state bounds on position, velocity, and acceleration. Later they extended the technique to many other cases, for example, to 3D open-chain kinematic robots under full Lagrangian dynamics. More recently, many practical heuristic algorithms based on stochastic optimization and iterative sampling were developed, by a wide range of authors, to address the kinodynamic planning problem. These techniques for kinodynamic planning have been shown to work well in practice. However, none of these heuristic techniques can guarantee the optimality of the computed solution, and none can be mathematically proven to be faster than the original PTAS algorithms.

Type of mobile robot
Legged robots are a type of mobile robot which use articulated limbs, such as leg mechanisms, to provide locomotion. They are more versatile than wheeled robots and can traverse many different terrains, though these advantages require increased complexity and power consumption. Legged robots often imitate legged animals, such as humans or insects, in an example of biomimicry.
Discipline related to computer vision and cartography
Robotic mapping is a discipline related to computer vision and cartography. The goal for an autonomous robot is to be able to construct a map or floor plan and to localize itself and its recharging bases or beacons in it. Robotic mapping is that branch which deals with the study and application of ability to localize itself in a map / plan and sometimes to construct the map or floor plan by the autonomous robot.
