As the research progresses, Roy says he'd like to add a collision-avoidancesystem using detectors to prevent the chair from bumping into other wheelchairs, walls or other obstacles.
随着进一步的研究，Roy称，他将会对轮椅系统增加防撞探测器，以防撞到其它轮椅、墙壁或者其它障碍物。

The current model, which is now being tested, may one day be equipped with cameras, laser rangefinders and a collision - avoidancesystem.
目前模型尚在测试中，将来的某一天可能会配备有摄像头，激光测距仪及防碰撞系统。

The smart displays provide navigation and collisionavoidance visualization from the radar sources and are used together with the Electronic Chart Display and Information System-Navy (ECDIS-N).
