The RiBot is an actuated robotic fish-lure that was designed to study the behavior of zebrafish. The design was based on the scan of a real zebrafish to produce the electronic boards and mechanics at the right scale. The robot can be controlled using Infrared RC5 signals and can beat its tail with different range of frequencies and amplitudes. The electronics was designed using the software Altium designer and the mechanics using CREO 3. The step file of the mechanics can be open by other types of CAD software. The firmware of the RiBot to program the electronics is described in: https://zenodo.org/record/830181#.WXtAIYTyipo The design of the lure is presented in detail in the following publication: F. Bonnet, N. Crot, D. Burnier and F. Mondada.
