Rock 'em Sock 'em Robots Live Hack (Part 11)

I've always loved the look of the Rock 'em Sock 'em Robots game but absolutely hated the feel of it. My goal will to robotize the game. I'll be adding in Micro HDD servos for the punching arms and 2 mini gantry systems for the X-Y movement. I'd like the game to feel like a real life super punch out! I hope to add the capability to play with two players (USB joysticks), or against an A.I. opponent. I'd also like to incorporate the power glove in some way. While I'm not a fan of robot violence I do have a special place in my heart for friendly, non-destructive, competition.

So much for finishing touches! Last week I applied too much current to the stepper motors and wrecked them. They no longer work. Time to find another way!

Challenges still left to do:

  • 3D design and print a new servo based XY movement system for each robot (Working on 3rd Prototype)
  • Tweak Software/Hardware for: Player vs Player and Player vs AI

Well right on, have a great Thanksgiving break! As for me I love total robot destruction and domination,why I build The Terminator and Cylon to combat each other in the near future, (Evil laughing).


I'm working on the third prototype for the servo driven X-Y gantry. It as designed in tinkerCAD and 3D printed on multiple Makerbot Rep 2 printers. There's still a bunch of revisions I had to do but I'm getting closer to something that will work. I still have to add the multiturn potentiometer to the servo for positional feedback. In initial testing it's crazy to see how much torque it has.

The third prototype has a smaller form factor and clearance. Made a few errors so it's onto the fourth prototype now. You'll notice that I switched the screws 180 degrees on the worm gear mount, this allows it to be mounted so much easier. I also made the worm gear beefier at the base because I had an issue with breakage on the second prototype (you can see the super glue if you look close).  The servo itself mounts very well now, but I'm still trying to think of a way to lock it in place.

Wow, I really gotta give it to you, really have out done yourself on this project .This will be the coolest sock'em robot game ever!


Here's an update to the servo driven XY gantry system. The proof of concept with the multiturn potentiometer works!

Although, after test fitting the gantry in the Rock em' sock em' base I figured out that there was no way that both the X and Y axes could be the same form factor, they had to be different. The Y axis (that moves robots closer to together) was fine being large in size but the X-axis (moves robots side to side) had to be significantly smaller. I printed out a X-axis version last night (see below). There are still some minor modifications that I'll have to make but it looks like this will work!
