This mechanical bunny wiggles its ears and can hop up a sloping wooden ramp using custom designed and built 4-bar linkages and slider cranks. The design was informed by engineering analysis of torque, power, and efficiency using Matlab and Working Model in addition to hands-on prototyping. It is powered by a 3V Pololu motor and connected with a system of custom laser cut acrylic gears, balsa wood body, masonite limbs, and off-the-shelf legos and fasteners. Completed as part of a team of 4 for Stanford Mechanical Sytsems Design class (ME 112)
