We presents the design and implementation process of one-time-use leaping mechanism for relocating energy-constrained sensor nodes. Towards its practical use, our focus is placed on how to realize a controllable locomotion mechanism that utilizes the ground reaction force generated. Specifically, our challenge lies in providing a practically reliable solution for a leaper triggering device which retains the pre-compressed actuators and selectively releases them. What is the most important aspect from the practical point of view is to examine whether the arbitrarily selected pre-compressed actuators can be self-triggered individually or in groups simultaneously, resulting in controlling the leaping distance and direction. The implementation details are explained, and both simulation and experimental results show that our prototype can be considered quite satisfactory for enhancing coverage and connectivity in sensor network applications.
