Gaming Robot

The forearm was bugging me, so I changed the shape

Earlier I mocked out some arms to be used with Dynamic Actuators which are about 4" in diameter. There are 2 problems with the arms. Firstly the torso with 4 actuators is a little heavy for dynamic actuators. Secondly, the arms look a little husky. Recently I found these...

They have a 36x gearbox, so I don't think they are back drivable, and hench not dynamic? But at 36x they have a little more torque, so I could use them with my 4 axis torso. Secondly they are 3" diameter so they look alittle sleaker. I made a second set of arms for the 3" 36x actuator. I think if someone wanted to make a "sport" robot, you could use a 2 axis torso with a rigid spine in the rib area, and use 4" dynamic actuators. If you didn't care about dynamics you could use a 4 axis spine with the 3" 36x actuator with the sleaker arms.

Recently worked out an arm shape I can live with. They look a bit "aggressive". My hope is that I can decorate the large looking triceps so that the forward portion looks like the arm, and a rearward portion looks like armor of some sort or maybe a crazy fashionable fluff of something. We'll see. Keep in mind I'm trying to keep all 3 actuators for the arm on the arm, and off the body. I think if I was building a nimble quad like Cheetah or Spot, this wouldn't work as well. I'll just have to keep motions slow and smooth.
