Good International's Cowa Robot autonomous carrier is one such example. The R1 Smart Carrier features four cameras on the handle and a laser sensor on the bottom to detect its surroundings and follow pedestrians. In addition to its four manual wheels, it also features two autonomous wheels. The handle-mounted manual driving mode sensor and autonomous driving mode switch allow the driver to change driving modes based on the situation.

When you wear the smart band, it detects your distance from the R1 and sends an alarm if you move too far away. If the band and carrier are separated by more than 5 meters, the carrier locks, and if they come within 30 centimeters, it unlocks. The GPS tracking feature helps you find your R1 if lost.

It has a range of 20 km, a maximum speed of 7.2 km/h, and a minimum speed of 0.72 km/h, which can be adjusted to the pedestrian's speed. It measures approximately 22 inches and weighs 4.5 kg. Its built-in, high-capacity battery allows it to be used not only as a carrier but also with other electronic devices, and its capacity is 24,900 mAh.
