摘要

—This paper presents a new fault tolerance schemesuitable for humanoid robot applications. In the future,various tasks ranging from daily chores to safety-relatedtasks will be carried out by individual humanoid robots.If the importance of the tasks is different, the requireddependability will vary accordingly. Therefore, for mobilehumanoid robots operating under power constraints, faulttolerance that dynamically changes based on the importanceof the tasks is desirable because fault-tolerant designsinvolving hardware redundancy are power intensive. In theproposed fault tolerance scheme, a duplex computer systemswitches between hot standby and cold standby according toeach individual task. However, in mobile humanoid robots, asafety issue arises when cold standby is used for the standbycomputer unit. Since an unpowered unit cannot immediatelystart to operate, a biped-walking robot falls down whenfailover occurs during cold standby. This paper proposes asafety failover method to resolve this issue and describes thehardware design of the safety failover subsystem.
