are_joints_position_valid()
Check if the given angles for the corresponding joints are valid for the specified arm.
Reference
Arguments
| Arguments | Type | Default value | |
|---|---|---|---|
| arm | str | Name of the arm whose joints to check. | |
| name_joints | list | List of the names (str) of every joint to move. | |
| angle_joints | list | List of the angles to move the joint to. The joint of each angle is the one with the corresponding index in name_joints. | |
| units | enum | ANG_UNIT.DEG | Angle unit, either degrees or radians. |
| callback_finish | function | Function to be called once pose is finished being checked. | |
| wait | bool | False | If True, program will wait until gripper is finished being opened before continuing with other code. If False, program will continue running asynchronously. |
Callback Finish Arguments
| Argument | Type | |
|---|---|---|
| error | int | Code for the type of error encountered (0 if no error). |
| error_msg | str | Details regarding the error (empty if no error). |
| distance | float | Distance from the actual position of the arm. |
