He'll get braver! Most robos come out a couple of times during the day. Orko is maybe still shy and building up confidence. The more he gets used to things the more confidence he will build up.
Our previous robo was a terrified type - if I put my hand in the cage he would run away and squish himself behind the wheel between the wheel and bars - knowing that was the only place I couldn't get at him probably. He'd had early scares with hands.
But he would happily come out in the cage during the day a couple of times and listen while I talked to him through the bars. They do vary.
Maybe try putting his veg out during the afternoon and see if he gets in the habit of waking up for that.
It's trial and error at first. Maybe leave it to 8 or 10 weeks. If you try the smelly food during the afternoon he might get used to getting up earlier before you do the spot clean
