  • IOP Conference Series: Materials Science and Engineering

    M.Allain, has researched on Blended Shared Control of a Hydraulic Excavator. An automatic control may be able to execute some quasi-repetitive construction tasks more efficiently than a human. This dichotomy has led to interest in Shared Control (SC) which synthesizes the advantages of both autonomous and manual control of machinery.

  • Blended Shared Control of Zermelo's navigation problem

    Many machines-from hydraulic excavators to mobile wheelchairs-are manually controlled by a human operator. In practice, the operator assumes responsibility for completing a given task at maximum utility, even though the optimal inputs may be unknown to the operator. Here we discuss a simple technique termed Blended Shared Control, whereby the human operator commands are continually merged with
