The reliability is an important issue for general systems. In IoT environments, the reliability is more important because an IoT application includes many IoT devices, gateways, and cloud servers. Applying a high overhead recovery mechanism to IoT devices that have resource constraints is difficult. In this paper, we designed a container-based checkpoint and restore system and ported the system to a wellknown open-source hardware platform (Raspberry Pi). By using this light-weight system, we can support seamless task handover between a fault robot and an alternative robot. We also implemented a testbed to verity the operability of the proposed system under a rescue robot scenario.
