Abstract: A control of a cooperative object-transporting robot which transports an object in cooperation with a man. The robot shares substantially a half of the weight of the object with the man, while the object is kept in a horizontal posture. A force applied to the robot by the object is detected by a force sensor, and based on the signal from the force sensor, a motion instruction is output for the motion components by the rotational force component &tgr;1 around the horizontal axis and the translational force component Fx1 in the horizontal back-and-forth direction, upon setting a gain to reduce the resistance forces of the robot to small values. The translational force component Fy in the direction of the object short axis is constrained so that no translational motion in the direction of the object short axis occurs.

Abstract: A source code translating method includes the steps of representing a particular source code in the form of an abstract syntax tree without using nodes representing expression statements, and converting such abstract syntax tree into a character string, wherein as the type of the root node in the abstract syntax tree being processed is if-statement (T71), a branch is taken to invoke the “procedure for producing if-statement” where a character string “if (” is first produced, and then, to produce “x==0” contained in the first occurrence of the subtree, the “procedure for outputting the abstract syntax tree as an expression” is recursively invoked, then a character string “)” is produced; to produce “y=0;” contained in the second occurrence of the subtree, the “procedure for outputting the abstract syntax tree as a statement” is recursively invoked, then a character string “else” is produced; and
