Best Robots for Serving Drinks at Events
ROBOT24.com compares three service robots for a specific event job: carrying filled cups through a room of standing guests and stopping where staff can collect them

Introduction
The real challenge for a drinks robot starts when it leaves the bar. It has to round a corner without sloshing drinks over the rims, pass groups of guests and stop where staff can reach the cups. Then it needs to get back for the next round.
That’s the route ROBOT24.com used to frame this ranking of the PUDU KettyBot Pro, KEENON DINERBOT T8 and OrionStar GreetingBot Mini. We scored each model on how well it fits the job, from keeping cups secure to signalling its arrival and getting ready for another run. The scores are based on editorial assessments and ROBOT24.com market data records; no controlled spill or handoff test was conducted.
At A Glance
| Rank | Robot | Editorial score | Standout in the scorecard | Best suited to |
|---|---|---|---|---|
| 1 | PUDU KettyBot Pro | 83.5/100 | Joint highest mark for guest access; highest mark for handoff cues | Staffed service points where a clear arrival cue matters |
| 2 | KEENON DINERBOT T8 | 82.0/100 | Matches the leader on cup fit, loaded route behaviour and guest access | Fixed drinks routes through rooms with standing guests |
| 3 | OrionStar GreetingBot Mini | 77.0/100 | Matches the other two on loaded route behaviour and reset | Short routes once the exact tray and cup fit are confirmed |
The Robots Behind the Rankings
1. PUDU KettyBot Pro: Best fit for clear handoffs
Overall editorial score: 83.5/100
KettyBot Pro leads by 1.5 points, entirely on its higher handoff score. It ties the DINERBOT T8 on the other four criteria, so the ranking gives it no edge on cup fit or how it travels with a load.
The useful check is at the destination: can staff tell when the robot has arrived, reach the cups without leaning across guests and send it back promptly? A clear handoff matters most when the same robot serves several points in quick succession.
2. KEENON DINERBOT T8: A close alternative for busy rooms
Overall editorial score: 82.0/100
DINERBOT T8 shares the top mark for access around standing guests and matches KettyBot Pro on loaded route behaviour. That makes it a close alternative when the route takes the robot past groups of guests before it reaches a fixed collection point.
To separate the two, run them through the same tight turn and planned stop with identical cups. Check where each robot comes to rest and whether staff can unload it without asking guests to move.
3. OrionStar GreetingBot Mini: A candidate once tray fit is confirmed
Overall editorial score: 77.0/100
GreetingBot Mini matches the other two on loaded route behaviour and reset in the editorial scorecard. It scores lower on tray and cup fit, the most heavily weighted criterion. The exact tray configuration is the first thing to confirm before including it in a drinks trial.
Check that the chosen cups sit securely and that staff can lift one without knocking its neighbours. Once the tray is confirmed, run it through the same course as the other two.
What should decide the ranking on the floor?
Start with KettyBot Pro and DINERBOT T8 for a side-by-side trial, and add GreetingBot Mini once its tray configuration is confirmed. Use the same cups, number of drinks, fill level, turns and stops. Repeat the route and record spills, cup movement, staff interventions and the time it takes to unload and send each robot back. That gives event teams a basis for choosing between models whose editorial scores are close.
