template<typename Types, typename Driver>
Types::BackendPtr create_finger_backend(typename Types::BaseDataPtr robot_data, const bool real_time_mode, const bool visualize, const double first_action_timeout = std::numeric_limits<double>::infinity(), const uint32_t max_number_of_actions = 0)

Create a Finger/TriFinger-backend using pyBullet.

Template Parameters:

  • Types – The struct providing the types for action, observation, etc.

  • Driver – pyBullet-Driver class for either single Finger or TriFinger.

Parameters:

  • robot_data – RobotData instance for the backend.

  • real_time_mode – If true, step the simulation in real time, otherwise as fast as possible.

  • visualize – If true, pyBullet’s GUI is started for visualization.

  • first_action_timeout – See RobotBackend

  • max_number_of_actions – See RobotBackend

Returns:

Backend using a driver of the specified type.

template<typename Action, typename Observation>
class BasePyBulletFingerDriver : public robot_interfaces::RobotDriver<Action, Observation>, public robot_interfaces::RobotDriver<Action, Observation>
#include <pybullet_driver.hpp>

Base driver for pyBullet of both single Finger and TriFinger.

Implements all methods of RobotDriver except initialize which needs to be implemented by the child class as there are differences between single Finger and TriFinger.

All other methods are generic and only need to be templated with the proper types for actions/observations.

Template Parameters:

  • Action – Action type used for the specific robot.

  • Observation – Observation type used for the specific robot.
