In thisletter, we present a novel optimization-based framework for autonomous excavator trajectory generation under task-specific constraints. Traditional excavation generators over-simplify the geometric parameterization thereby limiting space optimization. To expand search space, formulate generic task specification by constraining instantaneous motion of bucket and adding target-oriented con...

A challenging problem from a technological viewpoint is to send spacecraft at distance of about 600 au the Sun, comparable with that Sun’s gravitational focus (that is, general relativistic focusing light rays, whose minimum solar obtained when rays are assumed graze surface), and reach it in time interval on order human working lifetime. suitably oriented telescope would be theoretically able ...
