I have a simple question. I am wondering the reason why there is "over" in this sentence:
The boss of robotics company Boston Dynamics has confessed he once nudged his one-year-old daughter over to work out how people balance.
If I sad this sentence I would say "he once nudged his one-year-old daughter to work out how people balance." without "over". So does "over" contributes any additional meaning to this sentence? If it does, what is this? If it is not, why is there "over" in it?
