Waits until all Modules are homed.

Does homing for all Modules.

Homes only Schunk PW-Modules or PRL-Modules don't need to be homed.

PRL-Modules are ignored. PW-Modules are checked if they are homed. If not,homeing is executed.

getting offsets

wait until all modules are homed

start homing

std::vector< double > PowerCubeCtrl::getAccelerations ( )

Gets the current accelerations.

Gets the current positions.

ToDo: calculate new accelerations before returning

Definition at line 1181 of file PowerCubeCtrl.cpp.

std::string PowerCubeCtrl::getErrorMessage ( ) const [inline]

Get error message.

Definition at line 111 of file PowerCubeCtrl.h.

Gets the horizon (sec).

The horizon is the maximum step size which will be commanded to the powercube chain. In case of a failure this is the time the powercube chain will continue to move until it is stopped.

Definition at line 909 of file PowerCubeCtrl.cpp.

Get PC_Status message.

Definition at line 119 of file PowerCubeCtrl.h.

std::vector< double > PowerCubeCtrl::getPositions ( )

Gets the current positions.

Definition at line 1164 of file PowerCubeCtrl.cpp.

bool PowerCubeCtrl::getStatus ( PC_CTRL_STATUS status,
std::vector< std::string > &  errorMessages 
)

Gets the status of the modules.

Definition at line 1051 of file PowerCubeCtrl.cpp.

std::vector< double > PowerCubeCtrl::getVelocities ( )

Gets the current velcities.

Gets the current velocities.

ToDo: calculate new velocities before returning

open device

reset all modules of the chain

check number of modules connected to the bus

Check if the modules are connected

retrieve serial number

retrieve version number

retrieve defined gear ratio

retrieve axis type (linear or rotational)

find out module_type

otherwise success

check if modules are in normal state

Definition at line 117 of file PowerCubeCtrl.cpp.

bool PowerCubeCtrl::isInitialized ( ) const [inline]

Checking if is initialized.

Definition at line 103 of file PowerCubeCtrl.h.

bool PowerCubeCtrl::MoveJointSpaceSync ( const std::vector< double > &  angles)

Recovers the manipulator after an emergency stop.

modules successfully recovered

Definition at line 688 of file PowerCubeCtrl.cpp.

Configure powercubes to start all movements asynchronously.

Tells the Modules to start immediately

get config

set config to asynchronous

Definition at line 958 of file PowerCubeCtrl.cpp.

bool PowerCubeCtrl::setHorizon ( double  horizon)

Sets the horizon (sec).

The horizon is the maximum step size which will be commanded to the powercube chain. In case of a failure this is the time the powercube chain will continue to move until it is stopped.

Definition at line 896 of file PowerCubeCtrl.cpp.

bool PowerCubeCtrl::setMaxAcceleration ( double  maxAcceleration)

Sets the maximum angular velocity (rad/s) for the Joints, use with care!

Sets the maximum angular acceleration (rad/s^2) for the Joints, use with care!

A Value of 0.5 is already pretty fast, you probably don't want anything more than one...

Definition at line 835 of file PowerCubeCtrl.cpp.

bool PowerCubeCtrl::setMaxAcceleration ( const std::vector< double > &  accelerations)

Sets the maximum angular acceleration (rad/s^2) for the Joints, use with care!

Definition at line 865 of file PowerCubeCtrl.cpp.

bool PowerCubeCtrl::setMaxVelocity ( double  maxVelocity)

Sets the maximum angular velocity (rad/s) for the Joints, use with care!

A Value of 0.5 is already pretty fast, you probably don't want anything more than one...

Definition at line 776 of file PowerCubeCtrl.cpp.

bool PowerCubeCtrl::setMaxVelocity ( const std::vector< double > &  velocities)

Sets the maximum angular velocity (rad/s) for the Joints, use with care!

Definition at line 804 of file PowerCubeCtrl.cpp.

Configure powercubes to start all movements synchronously.

Tells the Modules not to start moving until PCube_startMotionAll is called.

get config

set config to synchronous

Definition at line 919 of file PowerCubeCtrl.cpp.

Returns true if any of the Joints are still moving.

Returns true if some cubes are still moving.

Should also return true if Joints are accelerating or decelerating

Definition at line 1149 of file PowerCubeCtrl.cpp.

Stops the Manipulator immediately.

Stops the manipulator immediately.

getting paramerters

stop should be executes without checking any conditions

after halt the modules don't accept move commands any more, they first have to be reseted

reset all modules of the chain

Definition at line 642 of file PowerCubeCtrl.cpp.

Returns the state of all modules.

Returns the current states.
