The convergence of mechanics and electronics in robotics brings with it lots of challenges. Because of 3D printing and low value parts, it’s doable to rapidly and simply experiment with quite a lot of robotics mechanism for varied use instances. [Paul Gould] has been doing precisely this, and is giving us a style of ten designs he will likely be open sourcing within the close to future. Video after the break.
Three of the designs are capstan mechanisms, with completely different motors and layouts, examined for [Paul]’s newest quadruped robotic. Capstan mechanisms are a number of centuries outdated, and had been initially used on crusing ships to present the required mechanical benefit to stress massive sails and hoist cargo.
Two of the mechanisms make use of GUS Simpson Drives, which use a mix of belts and a rolling joint. These had been impressed by the LIMS2-AMBIDEX developed on the College of Korea. The ever-popular cycloidal gearbox additionally makes and look within the type of a excessive torque twin disk linked, two stage, NEMA17 pushed gearbox.
[Paul] additionally constructed a room sized skycam-like claw robotic for his daughter, suspended by 4 ball chain strings reeled in by 4 brushless motors with ESP32 powered motor controllers. We’re wanting ahead to having an in depth have a look at these designs when [Paul] releases them, and to see how his quadruped robotic will end up.
