When Coldyron's alarm clock goes off, it says 5:00. When he gets out of bed, the clock says 4:50.
The meaning of the final "O.R." in the titular acronym "R.O.T.O.R." is inconsistent during the film; it's given as "Operation [singular] Research" in the title crawl, "Operations [plural] Research" on the door inside the Tactical Operations Lab, and "Operations Reserve" on the computer monitor when Coldyron queries R.O.T.O.R.'s status.
While Coldyron is waking up, feeding and riding his horse, and blowing up stumps, it is broad daylight, yet the sun is rising while he drives to work.
On Thursday, the sun begins to rise at 4:45 am; the next day, on Friday, Coldyron calls Dr. Steele at 5:45 and it's still dark out. Later, at 8:30 am ROTOR is recharging at a gas station and the sun is rising.
At the beginning, it's dusk when the lake-visiting traveler parks his car, but pitch-black when he exits it.
Dialogue identifies R.O.T.O.R. as a Dallas Police Department project; however, all prominent uniformed officers in the Tactical Operations Lab - Statum, the Motorpool Policeman, and Willard the Robot - wear shoulder patches from the neighboring northern suburb of Addison.
Coldyron throws ropes around R.O.T.O.R.. Some of the ropes go out over the water, and are held taut by nothing.
When Sony sits down at the truck stop restaurant, there are other patrons sitting at adjacent tables with coffee. As R.O.T.O.R. comes out of the kitchen, sound effects suggest that the other patrons are fleeing in panic, yet as R.O.T.O.R. approaches Sony, the chairs at the other tables are neatly pushed in and the coffee cups have vanished; the dining room is implausibly neat and tidy to have been vacated hastily.
It is likely that the sound effects were added as a makeshift post-production cover-up after the filmmakers realized that no scene had been filmed to explain the other patrons' disappearance, or an intervening sequence showing their orderly departure was cut from the movie.

Screw heads in chest area of animated "combat chassis" appear grossly oversize, revealing that it's a miniature model.
When Sony picks up the pay phone handset at the gas station, the hook switch stays down, and she is immediately connected to an operator without pressing any buttons. When using a real 1980s pay phone, the hook switch must pop up before the phone will work, and the user must dial "0" to speak to an operator.
The gas station cashier's kiosk is an obvious prop; it's a hollow unpainted wooden shell containing no cash register and very little merchandise. As R.O.T.O.R. reaches through the window, it's evident that there's no roof nor a counter for the register to sit upon, and the spindly-looking wooden framing is visible.
In the closing credits, there is the standard copyright citation -- including the "circle c" -- but no date is shown.
The scene in which R.O.T.OR. is at the garage fixing his bike. After the mechanic approaches and sets his radio down, he does something very odd. He approaches the truck and clearly looks like he's fainting and collapses to the ground. This is further evident by the position of his legs afterward. However, when R.O.TO.R. grabs the two battery cables, there is a cut to the mechanic underneath the truck, conscious, and repairing it.
When Sony blows the semi truck horn to disable R.O.T.O.R., he cowers in agony before the horn sounds.
Throughout the entire movie, none of Coldyron's dialogue matches his lip movement.
During the fight between ROTOR and Dr. Steele, you can see before he flips her that "she" is a male stunt double - evidenced by his glance at the camera and his armpit hairs.
Dash-mounted camera reflected in Coldyron's sunglasses during driving sequences with Dr. Steele.
Film crew reflected in Coldyron's sunglasses during various shots in the Tactical Operations Lab; some crew members are wearing light-colored and prominently visible T-shirts although no characters wearing T-shirts are being depicted.
The shadow of the camera is visible when Greg is shot in the head.
Perfect strangers eagerly help Sony evade ROTOR and fight him with little or no incitement even though aggravated assault on a police officer and hindering the apprehension of a fugitive are serious crimes in Texas.
ROTOR is affected by loud noise, including a loud radio, but seems unaffected by the sound of his roaring motorcycle or the sound of his own gun.
It's stated in dialogue that R.O.T.O.R. has no emotions or upper brain functions, yet he repeatedly reacts angrily when Sony evades him.
As pointed out on Rifftrax, ROTOR is not expected to be operational for years, yet already has its own locker and uniform.
