Flexure achieved with the telepresence robot finger
Initially, I'd planned to use a Meka Robotics trick of using latex rubber as half of the system to control flexure. As it turned out, however, the quarter inch rubber bands that I had planned on using proved too weak in tension to do the job properly. Instead, I rigged the finger with nylon cord.
As you can see here, it works rather well.
Stiffness in the joints of the finger creates a requirement for a bit more axial force in the control lines that I'd like, so I will be slightly redesigning the joints for a somewhat looser fit.
