Detailed Description

Radial Potential field. The computed gradient will be constant on volumnes with constant radius around the center of the potential field:

grad = (x - x0) / ||d||^{2}, ||d|| <= dMax = 0 , else

with: d = x - x0 = Distance to field dMax = Maximum Influence distance x = current position x0 = Potential field center

Constructor & Destructor Documentation

RadialPotentialField()

RadialPotentialField::RadialPotentialField	(	const uint	_dimension,
		const std::string &	_name = "" )

Init all members. Dimension of the field. Has to be > 0. e.g. a field in Cartesian space would have dimension 3.

~RadialPotentialField()

virtual wbc::RadialPotentialField::~RadialPotentialField ( )

Member Function Documentation

update()

const base::VectorXd & RadialPotentialField::update ( const base::VectorXd & position )

virtual

Compute control update according to potential field equation.

Returns

Computed gradient. Size will be same as dimension.

Implements wbc::PotentialField.
