robot_interfaces_bolt.bolthumanoid module

class robot_interfaces_bolt.bolthumanoid.Action

Bases: pybind11_object

Action for BoltHumanoid

Zero()

Create a zero-torque action

property joint_position_gains

P-gains for the on-board controller, one per joint.

property joint_positions

Desired joint positions of the P controller running on the card. For this to have an effect joint_position_gains needs to be set as well.

property joint_torques

List of desired torques, one per joint.

property joint_velocities

desired joint velocity of the D controller running on the card. For this to have an effect, joint_velocity_gains needs to be set as well.

property joint_velocity_gains

D-gains for the on-barod controller, one per joint.

class robot_interfaces_bolt.bolthumanoid.BinaryLogReader(filename: str)

Bases: pybind11_object

See read_file().

property data

Contains the log entries.

Type:

List[LogEntry]

read_file(filename: str)

Read data from the specified binary robot log file.

The data is stored to data.

Parameters:

filename (str) – Path to the robot log file.

class robot_interfaces_bolt.bolthumanoid.Config

Bases: pybind11_object

from_file()

Load configuration from a YAML file (using default values for parameters missing in the file).

property home_offset_rad

Offset between home position (=encoder index) and zero position.

Angles (in radian) between the encoder index and the zero position of each joint.

property max_motor_current_A

Maximum current that can be applied to the motors (in Ampere).

property network_interface

Name of the network interface to which the robot is connected (e.g. ‘eth0’)

property slider_serial_port

Name of the serial port to which the hardware slider is connected. This can typically be left empty, in which case the port is auto-detected.
