Best Mobile Advertising Robots for Retail Entrances

Introduction

The entrance to a store is some of the most valuable advertising space a retailer has. Everyone uses it, but just for a few moments. A mobile advertising robot earns its right to be there if it can actually be seen and its message taken in by shoppers, and if its message can be changed quickly by staff whenever a promotion changes.

In this ranking, the OrionStar GreetingBot AD, KEENON DINERBOT T10 and PUDU KettyBot Pro are compared for this task. While the GreetingBot AD is designed primarily as an advertising robot, the T10 and KettyBot Pro are delivery robots with large advertising screens. This comes through in their scores, which are separated on the basis of display visibility more than anything else.

Each robot is rated out of 10 on five weighted criteria: display visibility, positioning and mobility, customer interaction, operating continuity and campaign controls. Total scores out of 100 and the ranking order are based on ROBOT24’s desk review. This ranking is based on capability and editorial assessment and not on testing at a store entrance. The methodology is below.

AT A GLANCE

Rank	Robot	Overall score	Standout specification	Best suited to
1	OrionStar GreetingBot AD	83.5/100	21.5-inch advertising display plus 14-inch touchscreen	Entrances where the robot’s main job is advertising
2	KEENON DINERBOT T10	81.0/100	23.8-inch screen with movable heads	Food halls and stores that also need a delivery robot
3	PUDU KettyBot Pro	80.5/100	18.5-inch ad screen; 52 cm minimum aisle width	Compact entrances where interaction matters most

The Robots Behind the Rankings

1. OrionStar GreetingBot AD: The dedicated advertising robot

Overall score: 83.5/100

The OrionStar GreetingBot AD takes first place and earns the only perfect score in this comparison: 10/10 for display visibility. Unlike the other two robots, it is built first and foremost as a mobile billboard. OrionStar describes it as a marketing service robot that combines proactive greeting, mobile advertising and guided selling.

Its hardware reflects that focus. OrionStar lists a 21.5-inch full-HD advertising display on the chest and a separate 14-inch touchscreen on the head, so the promotion keeps running while a shopper interacts with the robot. It detects visitors as they arrive, greets them, and can answer product and promotion questions in more than 46 languages, according to OrionStar. It scores 8/10 for positioning and mobility, customer interaction and campaign controls.

Its weaker area is operating continuity, at 7/10. OrionStar lists a runtime of 8 to 10 hours with automatic docking, so stores that open for long hours will need to plan when it goes back to charge. It also needs a 60 cm minimum aisle width. The GreetingBot AD suits store and mall entrances where advertising is the robot’s main purpose, not a side feature.

2. KEENON DINERBOT T10: Large-screen promotion with delivery on the side

Overall score: 81.0/100

The KEENON DINERBOT T10 finishes second. KEENON markets it as a delivery and marketing robot, and it scores 9/10 for display visibility, one point behind the GreetingBot AD.

KEENON lists a 23.8-inch screen, movable heads that react to touch and movement, and interactive buttons. The screen is larger than the GreetingBot AD’s advertising display, but the T10 has a single main screen and is designed around food delivery, which helps explain the one-point gap. It scores 8/10 for positioning and mobility, customer interaction and campaign controls, and KEENON lists app-based remote task management.

Like the other two robots, it scores 7/10 for operating continuity. KEENON lists 9 to 12.5 hours of battery life and a 5.5-hour charge. Its 59 cm minimum passage width suits most entrance areas.

The DINERBOT T10 suits food halls, quick-service restaurants and food retail where one robot needs to advertise at the entrance and run deliveries.

3. PUDU KettyBot Pro: The most interactive model
Overall Score: 80.5/100

The PUDU KettyBot Pro is only slightly less effective than the T10, losing half a point, but the highest score in terms of customer engagement – 9/10 – belongs to this model.

According to retailer listings, it has an advertising screen of 18.5 inches and an additional touchscreen screen of 10.1 inches, featuring AI voice interaction enabling it to greet the customers and interact with them through its screen content. With PUDU’s Open Platform, the operators can personalize the robot's expressions, voice and content. It scores 8/10 for display visibility, positioning and mobility, and campaign controls.

Its smaller advertisement screen is the main cause for its low score in terms of display visibility. Operating continuity scores 7/10; according to retailers, it features automatic return to the dock when the battery level is low, although run-time data differs depending on sellers. Its 52 cm minimum aisle width makes it the easiest to fit in a tight entrance.
The KettyBot Pro is recommended for small stores and entrances when customer engagement is a priority over the size of the screen.

The best match will depend on the entrance

The difference between the three robots is only 3 points. The best dedicated advertising robot is OrionStar GreetingBot AD which is at the top with the highest display score. The KEENON DINERBOT T10 is the best option when one robot is required to promote and deliver. The most interactive and space-efficient robot is the PUDU KettyBot Pro.

The fairest decision will be a fair test of all three. Two things should be considered in detail: shoppers’ ability to see and perceive the message and the ease of changing it by the staff. Play the same advertising loop for all three robots in the same entrance and same venue lighting conditions, then measure readability of the message from a few metres and the time of changing campaigns.

In general, the decision will depend on the dimensions and layout of the entrance, operating hours of the store, campaign changing frequency and additional responsibilities (delivery or guiding).

RANKING EXPLAINED

Parameter	What we assess	Weight
Display visibility	Screen size, placement and how easily shoppers can see and take in the message.	25%
Positioning and mobility	Ability to hold a good spot at the entrance, move through busy areas and fit narrow spaces.	25%
Customer interaction	Greeting, voice, touch and how well the robot engages shoppers who stop.	20%
Operating continuity	Run time, charging time and automatic docking across store opening hours.	15%
Campaign controls	How easily staff can upload, schedule and change promotional content.	15%

Each criterion is scored out of 10, and the weighted scores combine into an overall score out of 100. Display visibility and positioning carry the most weight because a message only works if shoppers see it in the right place.
