Why Does Your Bag “Walk Itself”? A Technical Look at the icango golfcaddy G5’s UWB Smart Follow System

After finishing 18 holes under the sun, I was a bit dazed walking back. Then Lao Zhang from my group called out: “Don’t move—stand right next to your trolley.” He and another buddy flanked me, had the caddie snap a photo, and grinned: “This is going on social media with the caption ‘Today I saw the future.’”

They were talking about my icango golfcaddy G5.

Most people react the same way the first time they see it. From a distance, it looks like a standard push cart. Up close, you notice nobody’s pushing it—it’s moving on its own. You go left, it goes left. You stop, it stops. It stays about 1.8 meters behind you, a distance you can fine-tune in the mobile app—along with cruise control, remote mode, and other settings.

What Makes It Follow So Accurately? UWB, Not AI Vision 

Two common approaches exist in the smart trolley market: AI vision follow​ and ultrasonic + RF follow. Both have known weaknesses. AI vision struggles in harsh sunlight or low light, and tends to drift in crowded spaces. Ultrasonic + RF systems suffer from signal interference when multiple trolleys operate nearby, and accuracy drops at longer distances.

The G5 uses UWB (Ultra-Wideband) positioning technology. In simple terms, the small remote you wear continuously emits pulse signals. The receiver module on the trolley calculates real-time distance and direction by measuring the signal’s time of flight. This method is unaffected by lighting conditions, offers strong interference resistance, and achieves centimeter-level positioning accuracy. Whether you’re turning a corner or climbing a slope, it tracks you steadily—far more precise and reliable than common AI facial-recognition follow systems. On tight turns, you might glance back once; most of the time, you forget it’s even there.

Specs & Real-World Testing 

• Weight & Load Capacity: The G5’s net weight is kept under 19 kg, yet its load capacity is impressive. My bag packed with irons, wedges, two water bottles, and a jacket—no problem at all. When folded, it’s roughly the size of a large carry-on suitcase, fitting easily into any sedan trunk.

• Battery Range: Officially rated in the 45-hole class. I’ve tested it twice: two full rounds (36 holes) on a single charge with juice left over—more than enough for a weekend trip.

• Hill Climb & Descent: Rated for 20° slopes. More interesting is downhill behavior—many auto-follow trolleys struggle to brake on descents. The G5 automatically reduces speed​ on steeper sections and holds position without rolling backward​ when parked on an incline, thanks to its motor control system and parking brake logic.

• Optional Seat: A seat attachment is available, letting you sit down and rest whenever needed—especially friendly for golfers with lower stamina.

• Removable Battery: Allows separate charging and compact storage, so you don’t have to park the whole trolley next to an outlet.

Why This Beats “Hiring a Caddie” 

A good caddie is valuable, but a caddie inevitably influences your stance, rhythm, and timing. The G5 does something simpler: it turns your bag into your shadow. You decide where to stop, how long to read a putt, which line to walk. It simply keeps your gear positioned and ready. No waiting, no adjusting to someone else’s schedule. That ownership of your own pace​ is the real luxury.
