Bases: pybind11_object

property move_steps

Number of time steps for reaching the target position.

property target_position_rad

Target position to which the joints should move.

property calibration

Parameters related to calibration.

property can_ports

List of CAN port names used by the robot.

property hard_position_limits_lower

Hard lower limits for joint positions.

property hard_position_limits_upper

Hard upper limits for joint positions.

property has_endstop

Whether the joints have physical end stops or not.

property home_offset_rad

is_within_hard_position_limits(self: robot_fingers.py_solo_eight.SoloEightConfig, position: numpy.ndarray[numpy.float64[8, 1]]) → bool

is_within_hard_position_limits(position: list) -> bool

Check if the given position is within the hard limits.

Parameters:

position – Joint positions.

Returns:

True if hard_position_limits_lower <= position <= hard_position_limits_upper.

static load_config(config_file_name: str) → robot_fingers.py_solo_eight.SoloEightConfig

load_config(config_file_name: str) -> Config

Load driver configuration from a YAML file.

Parameters:

config_file_name – Path to the config file.

Returns:

The configuration loaded from the given file.

Maximum current that can be sent to the motor [A].

property move_to_position_tolerance_rad

Tolerance for reaching the target with NJointBlmcRobotDriver::move_to_position()

property position_control_gains

Default control gains for the position controller.

print(self: robot_fingers.py_solo_eight.SoloEightConfig) → None

print()

Print the configuration.

property safety_kd

D-gain to dampen velocity. Set to zero to disable damping.

property shutdown_trajectory

Trajectory which is executed during shutdown.

property soft_position_limits_lower

Soft lower limits for joint positions.

property soft_position_limits_upper
