I love the idea of this robot, whose sole purpose is to be sneaky and by design he's clearly not. The voices were fine, and I loved the gags! SFX and music were on point as well.

What keeps this from getting a perfect score to me was pace. The world-building introductory text-crawl would only really be needed if you intended to expand upon this character and setting, but if this is a one-shot, is kinda unnecessary. The audience wouldn't think twice that, for whatever reason, they're sending this inept sneak-bot to save the president.

Also, what's up with this world's Colonel Campbell; maybe it's because he's an old white guy with white hair dressed in white, but I'm getting a serious Colonel Sanders vibe if we threw on a Daffy Duck sailor hat and slapped a Cyber eye-patch on him.

Some of the gags necessitated padding, like the slow trudge of the clunky tank treads, and slowly reversing, and that's totally fine but it helped provide the sense that the overall pace was kinda slowly trudging, there was nothing inherently quick to switch up the pace. With some minor tweaking into comedic timing, the jokes could punch more as well as quicken the pace of the overall short.

Having said all of that, I think you did great! Voted 5!
