class | Breadcrumbs |
A system for creating Breadcrumbs in the form of models that can get deployed/spawned at the location of the model to which this system is attached. Each breadcrumb is a complete sdf::Model. When deployed, the pose of the breadcrumb model is offset from the containing model by the pose specified in the <pose> element of the breadcrumb model. A name is generated for the breadcrumb by appending the current count of deployments to the name specified in the breadcrumb <model> element. The model specified in the <breadcrumb> parameter serves as a template for deploying multiple breadcrumbs of the same type. Including models from Fuel is accomplished by creating a <model> that includes the Fuel model using the <include> tag. See the example in examples/worlds/breadcrumbs.sdf. More... | |

class | WheelSlip |
A system that updates wheel slip parameters based on linear wheel spin velocity (radius * spin rate). It currently assumes that the fdir1 friction parameter is set parallel to the joint axis (often [0 0 1]) and that the link origin is on the joint axis. The slip parameter is a Force-Dependent Slip (slip1, slip2) and it has units of velocity / force (m / s / N), similar to the inverse of a viscous damping coefficient. The slip_compliance parameters specified in this plugin are unitless, representing the lateral or longitudinal slip ratio (see https://en.wikipedia.org/wiki/Slip_(vehicle_dynamics) ) to tangential force ratio (tangential / normal force). Note that the maximum force ratio is the friction coefficient. At each time step, these compliances are multiplied by the linear wheel spin velocity and divided by the wheel_normal_force parameter specified below in order to match the units of the slip parameters.
