Detailed Description

Abstract interface class for providing access to a generic robotic platform with bicycle steering.

Member functions throw Exception on error conditions.

The implementations of this interface are not expected to be thread-safe.

Member Function Documentation

virtual void hydrointerfaces::Bicycle::enable

(

)

[pure virtual]

Throws Exception on failure. It is not an error to call this repeatedly: repeated calls should re-initialise the hardware. (eg this will be called if the hardware reports an error condition)

virtual void hydrointerfaces::Bicycle::getStatus	(	std::string &	status,
		bool &	isWarn,
		bool &	isFault
	)			[pure virtual]

Get information about the current status of the driver. the string 'status' is a human-readable description. Note that there are two ways for faults to be notified:

• This function tells of hardware faults reported normally by the hardware.
• Exceptions can be thrown from read/write for non-recoverable faults, such as inability to communicate with the hardware.

virtual bool hydrointerfaces::Bicycle::read

(

Data &

data

)

[pure virtual]

Blocking read. Returns: true: important change in internal state occured (details can be read with getStatus). false: no important change
