Detailed Description

Command objects have various fields that can be set; when sent to the module, these fields control internal properties and setpoints.

This object has a hierarchical structure – there are some direct general-purpose fields at the top level, and many more specific fields contained in different nested subobjects.

The subobjects contain references to the parent command object, and so should not be used after the parent object has been destroyed.

The fields in the command object are typed; generally, these are optional-style read/write fields (i.e., have the concept of get/set/has/clear), although the return types and exact interface vary slightly between fields. Where appropriate, the explicit bool operator has been overridden so that you can shortcut if(field.has()) by calling if(field).

Although this header file can be used to look at the hierarchy of the messages, in general the online documentation at apidocs.hebi.us presents this information. in a more readable form.

Member Enumeration Documentation

enum hebi::Command::ControlStrategy

strong

Enumerator
Off	The motor is not given power (equivalent to a 0 PWM value)
DirectPWM	A direct PWM value (-1 to 1) can be sent to the motor (subject to onboard safety limiting).
Strategy2	A combination of the position, velocity, and effort loops with P and V feeding to T; documented on docs.hebi.us under "Control Modes"
Strategy3	A combination of the position, velocity, and effort loops with P, V, and T feeding to PWM; documented on docs.hebi.us under "Control Modes"
Strategy4	A combination of the position, velocity, and effort loops with P feeding to T and V feeding to PWM; documented on docs.hebi.us under "Control Modes"

Definition at line 35 of file command.hpp.

enum hebi::Command::MstopStrategy

strong

Enumerator
Disabled	Triggering the M-Stop has no effect.
MotorOff	Triggering the M-Stop results in the control strategy being set to 'off'. Remains 'off' until changed by user.
HoldPosition	Triggering the M-Stop results in the motor holding the motor position. Operations resume to normal once trigger is released.

Definition at line 51 of file command.hpp.

enum hebi::Command::PositionLimitStrategy

strong

Enumerator
HoldPosition	Exceeding the position limit results in the actuator holding the position. Needs to be manually set to 'disabled' to recover.
DampedSpring	Exceeding the position limit results in a virtual spring that pushes the actuator back to within the limits.
MotorOff	Exceeding the position limit results in the control strategy being set to 'off'. Remains 'off' until changed by user.
Disabled	Exceeding the position limit has no effect.
