class SimpleTransmission : public transmission_interface::Transmission

Public Functions

inline explicit SimpleTransmission(const double joint_to_actuator_reduction, const double joint_offset = 0.0)
Parameters:

  • joint_to_actuator_reduction – [in] Joint to actuator reduction ratio.

  • joint_offset – [in] Joint position offset used in the position mappings.

Pre:

Nonzero reduction value.

inline virtual void configure(const std::vector<JointHandle> &joint_handles, const std::vector<ActuatorHandle> &actuator_handles) override

Set up the data the transmission operates on.

Parameters:

  • joint_handles – [in] Vector of interface handles of one joint

  • actuator_handles – [in] Vector of interface handles of one actuator

Pre:

Vectors are nonzero.

Pre:

Joint handles share the same joint name and actuator handles share the same actuator name.

inline virtual void actuator_to_joint() override

Transform variables from actuator to joint space.

This method operates on the handles provided when configuring the transmission. To call this method it is not required that all supported interface types are provided, e.g. one can supply only velocity handles

inline virtual void joint_to_actuator() override

Transform variables from joint to actuator space.

This method operates on the handles provided when configuring the transmission. To call this method it is not required that all supported interface types are provided, e.g. one can supply only velocity handles

inline virtual std::size_t num_actuators() const override
Returns:

Number of actuators managed by transmission, ie. the dimension of the actuator space.

inline virtual std::size_t num_joints() const override
Returns:

Number of joints managed by transmission, ie. the dimension of the joint space.
