One embodiment of the present invention provides a system for determining whether software is likely to exhibit malicious behavior by analyzing patterns of system calls made during emulation of the software. The system operates by emulating the software within an insulated environment in a computer system so that the computer system is insulated from malicious actions of the software. During the emulation process, the system records a pattern of system calls directed to an operating system of the computer system. The system compares the pattern of system calls against a database containing suspect patterns of system calls. Based upon this comparison, the system determines whether the software is likely to exhibit malicious behavior. In one embodiment of the present invention, if the software is determined to be likely to exhibit malicious behavior, the system reports this fact to a user of the computer system. In one embodiment of the present invention, the process of comparing the pattern of system calls is performed on-the-fly as the emulation generates system calls.

The present invention provides a multi-joint robot that, when the loads acting on some of joints are overloaded, controls the joints so as to continue the work as far as possible while easing the overloaded state. The load estimate unit (32) estimates the load acting on each joint, and the overloaded joint specifying unit (34) specifies an overloaded joint of which the estimated load is greater than a threshold. The storage unit (40) stores a target state vector of an end link of the robot and stores a predetermined priority with respect to the components of the vector. The component extracting unit (42) extracts the same number of components as that of non-overloaded joints from the target state vector in order of a higher priority. The force control calculating unit (36) determines the target drive quantity for driving the overloaded joint in the same direction as that of the load. The inverse transformation unit determines the target drive quantities with respect to the non-overloaded joints so as to realize the extracted components. Thus, the non-overloaded joints can be controlled so as to follow the target state vector as far as possible, while the overloaded joints are controlled in a direction to reduce the load.
