In this simulation, 66 of the 100 needles crossed a line (you can count ’em). Using this number, we get a value of pi at 3.0303—which is not 3.14—but it's not terrible for just 100 needles. With ...
Abstract: In order to expand the configuration of the leg mechanism of a legged robot, a Parallel Mechanical Leg (PML) with two rotational and three translational degrees of freedom (DOF) is proposed, ...
