Epicyclic Gear Train Solution Techniques with Application to Tandem Bicycling
… methods for the design and analysis of planetary gear trains along with a discussion of potential applications in tandem biking. Specifically, this thesis will provide a simple solution technique for the general case of a two-degree of freedom (2DOF) planetary gear train along with new graphical …

Analysis of a Split-Path Gear Train with Fluid-Film Bearings
In the current literature, split path gear trains are analyzed for use in helicopter transmissions and marine gearboxes. The goal in these systems is to equalize the torque in each path as much as possible. There are other gear trains where the operator intends to hold the torque split unevenly. …

Bipedal Walking for a Full Size Humanoid Robot Utilizing Sinusoidal Feet Trajectories and Its Energy Consumption
… and lesions learned from CHARLI-L, CHARLI-2 uses gear train reduction mechanisms, instead of parallel four-bar linkages, to increase actuation torque at the joints while further reducing weight. Both robots successfully demonstrated untethered bipedal locomotion using an intuitive walking method …
