Parallel Parking

Swan "parallel-parks" itself between two cars, as human drivers do. In the first video, Parallel Parking, the robot scans "cars" parking on its right side with its sonars, then computes the best position and direction for backing in safely. There is a four-second waiting time before Swan leaves the parking spot.

In this case, the space between the two cars is 750 mm. The body length and width of Swan are 429 and 270 mm respectively, and the distance between the body center and rotation center is 126 mm. The trajectory is this. The mock-up cars have the same dimensions as those of Swan.

The second video, Parallel Parking: Tight, demonstrates the minimum space required for MotionMind/Swan to parallel-park. The minimum space is 530 mm, just 101 mm longer than Swan itself. The trajectory is this. This result is reliable and repeatable.

Two functional components of the MotionMind Engine work together to make parallel parking possible: (1) precise Park Backward/Forward motions that are presented in the Motion Simulation page, and (2) estimation of precise car positions via noisy sonar data. Actually both are geometrical problems, and Symmetric Geometry takes care of these problems.

This performance surpasses any human driver's skills because humans are not equipped with Symmetric Geometry. This technology can be easily applied to every automobile to make driving safer and drivers happier.
