Parameters:

obstacle_positionarray, shape (2,)

Position of the point obstacle.

gammafloat, optional (default: 1000)

Parameter of obstacle avoidance.

betafloat, optional (default: 20 / pi)

Parameter of obstacle avoidance.

Methods

coupling(y, yd)

Computes coupling term based on current state.

__init__(obstacle_position, gamma=1000.0, beta=6.366197723675814, fast=False)
