Solid robot with high release point.

What type of linear punch mechanism ? pnuematic , motor ?

[dellagd]

The puncher operates through two carriages that ride on linear bearings. The back one (retract carriage) is driven by a leadscrew across the length of the puncher. The front one (puncher carriage) has a bolt for the retract carriage to grab on its back, a puncher rod on its front, and surgical tubing for stored energy on its front as well.

The whole sequence involves running the retract carriage forward, pneumatically grabbing the puncher carriage, and then pulling it back, stretching the surgical tubing. The retract carriage then pneumatically releases the puncher when we want to fire.

The first scene in the reveal video is from the underside of the arm and showcases the whole mechanism. I dont actually have a number for the force at max stretch, but I would estimate it is about 100lbs (using 8 surgical tubes). Using that many, we stretch the bands to about 240% original length, which should let them last much longer than exceeding 300%.

Another solid robot from 2607. Looking forward to seeing it this weekend!
