Towards Rapid Mechanical Customization Of Cm-Scale Self-Folding Agents
2017 IEEE/RSJ INTERNATIONAL CONFERENCE ON INTELLIGENT ROBOTS AND SYSTEMS (IROS)(2017)
摘要
Large robotic collectives provide advantages such as resilience to mechanical failure of single agents and increased capabilities for search and coverage based applications. However, a lack of rapid and free-form manufacturing processes remains a barrier to high-volume fabrication of mechanically heterogeneous robotic swarms. Self-folding laser-machined structures have the potential to enable heterogeneous robotic swarms. As an initial step to realizing a functional robotic collective, we focus on the design and characterization of the locomotion of an individual laminate manufactured robot. We look to a vibration-based locomotion technique that uses flexible structures or bristles to enhance the effects of vibration, allowing for fast locomotion (i.e. a "bristle-bot"). However, previous bristle-bot implementations have not allowed for controllable steering behaviors with high locomotion speeds. We describe the extension of existing two dimensional bristle-bot models to a three dimensional model that explores parameters that govern linear and angular velocity. We implement an autonomous laminate-manufactured bristle-bot inspired robot capable of linear velocities of up to 23 cm/s and turning rates of 2 rad/s. Moving towards automated manufacturing, we also demonstrate a self-folding bristle-bot structure that uses a linear compression laminate to achieve a uniform leg fold angle.
