I had the following hand when playing SAYC-like with a robot:
♠4 ♥108743 ♦KQJ7 ♣AQ10

Partner had
♠AQ982 ♥QJ6 ♦A ♣K875

The bidding went as follows (I opened): 1♥ (12+ HCP with 5+ hearts) - 1♠ - 2♦ (good diamond suit, no spade fit) - and then North suddenly blasted to 6♥. Of course, for the obvious reasons (missing AK of trumps), it went down 1.

So, why did North bid a slam without further investigating (Blackwood etc), since I didn't promise the strength of my heart suit (opposed to length)? Or maybe I shouldn't open with my long major being not good enough?

Robot is stupid

[smerriman]

Which robot are you playing with, out of interest? Doesn't sound like a very good one.

Even GIB, the robot everyone loves to hate, bids 3♣, 4sf.

You did nothing wrong.

6H is clearly ridiculous, but the auction is a problematic one. Say North bids 3C and you bid anything other than 3D - how does North set hearts and look for slam now? Here you're going to bid 3NT, and I don't know what GIB's options are at this point.

A partnership needs good agreements to deal with a 4SF bid at the three-level, otherwise the auction may not be much more informative than the one the robot chose.

For Russians, GIB plays the Putin Club system. Defenders should crash ♥A and ♥K on the same trick to avoid getting sent to a gulag in Siberia.

I reckon opposite a half decent (even average) 5 card opening heart bid its not a bad attempt (very approx averagish 75% plus or minus a fair bit chance of double dummy), but even I at my lowly robot-type level like to check for some controls, and remove some of the error variance occasionally. Saadly also despite having a fairly healthy mean chance of making it the mean number of tricks is less than 12 (dont know why) Do people really expect 100% accuracy from anything human or robot

I'm going to think twice opening a heart suit like that in future

Just a value bid. Checking for 2 missing keycards after calculating the partnershipo has the values isn't programmed I guess, the programmers don't play Bridge afterall.

Ouch. Robots tend to overuse point count (they double count honors + shortness). Something to be said for rebid of 1NT with 12-14.
Worth considering suit quality in first or second seat. It sometimes is worth while passing this hand first, although it goes against the grain playing with a real partner1

(Even if ♥A&♥K are both in one defender's hand, they will crash on one trick when playing Putin Club system)

Playing SAYC while GIB is playing 2/1 should lead to some confusing auctions.

OP has stated in an earlier post they are playing with a different robot, not GIB.

The purpose of the 6H bid was to apprise you that you need to find better bots

Well, not all of them. I'm actually a programmer and I'm at least trying to play bridge.
