Syntax

robotRBT = loadrobot(robotname)
[robotRBT,robotData] = loadrobot(robotname)
[robotRBT,robotData] = loadrobot(robotname,Name,Value)

Description

example

robotRBT = loadrobot(robotname) loads a robot model from the robot library as a rigidBodyTree object specified by robot model name robotname.

To import your own robot model from a Unified Robot Description Format (URDF), XML Macros (Xacro), or Simulation Description Format (SDF) file or Simscape™ Multibody™ model, see the importrobot function.

[robotRBT,robotData] = loadrobot(robotname) returns additional information about the robot model as a structure, robotData.

[robotRBT,robotData] = loadrobot(robotname,Name,Value) specifies additional options using one or more name-value pair arguments. For example, 'Gravity',[0 0 –9.81] sets the gravity property to –9.81 m/s2 in the z-direction for the robot model.

Note

To use the rigidBodyTree model of the robot generated by loadrobot with smimport (Simscape Multibody) function, you must download and install the Robotics System Toolbox Robot Library Data support package from File Exchange. For more information, see Install Robotics System Toolbox Robot Library Data Support Package.

Data Types: char | string

Name-Value Arguments

Specify optional pairs of arguments as Name1=Value1,...,NameN=ValueN, where Name is the argument name and Value is the corresponding value. Name-value arguments must appear after other arguments, but the order of the pairs does not matter.

Before R2021a, use commas to separate each name and value, and enclose Name in quotes.

Example: 'Gravity',[0 0 -9.81] sets the gravity property to -9.81 m/s2 in the z-direction for the robot model.

Input/output data format for the kinematics and dynamics functions of the robot model, specified as the comma-separated pair consisting of 'DataFormat' and "struct", "row", or "column". To use dynamics functions, you must specify either "row" or "column". This name-value pair sets the DataFormat property of the rigidBodyTree robot model.

Gravitational acceleration experienced by robot, specified as the comma-separated pair consisting of 'Gravity' and a three-element vector of the form [x y z] in m/s2. Each element corresponds to the acceleration of the base robot frame in the x-, y-, and z-direction, respectively. This name-value pair sets the Gravity property of the rigidBodyTree robot model.

URDF version of the robot model, specified as a numeric scalar.

Robot ModelVersions
"kinovaGen3"1 –– Loads the kinovaGen3.urdf robot model
2 –– Loads the kinovaGen3V12.urdf robot model

Example: loadrobot("kinovaGen3","Version",2)
