t5 timing belt pulley used as elbow/knee

You'll use these wheels as part of a transmission system that utilizes its joint mechanisms to exert powerful pulls across specific leg sections, as seen in the accompanying photo. Notably, the cockroach-inspired design incorporates six robust legs, each featuring an average of 4 articulating joints that can rotate through a full range of motion of about 6 degrees apiece. However, to ensure seamless operation, at least two high-performance SMA muscles will be required for every single joint to achieve proper mobility. Meanwhile, when integrating this intricate transmission system with our larger-than-life human-scale vehicle design - which boasts an awe-inspiring ride-on human hand that functions in a surprisingly practical and straightforward manner - we opt to repurpose the existing leg assemblies as sturdy, articulated fingers. Given that actual hands operate on a similarly compact and efficient mechanical configuration, with joints allowing only 2 degrees of pivotal freedom each time they're moved, we make substantial reductions to the initial size specifications of our componentry. As such, instead of implementing those overly massive pulleys originally used for our roach-legged behemoth, we can utilize these far more diminutive yet impressively engineered t5 pulley components - capable of meeting all performance expectations and handling their share of stresses within our system's overall structural integrity framework.
