Picture this: You're at the airport and a robot is guiding you to your gate. You walk past another bot that's breakdancing, to the delight (or despair) of passengers waiting for a delayed flight. 

Up ahead, someone speeds along in an autonomous single-rider vehicle. Before hopping on your flight, you fill up your water bottle -- which also tracks your water intake. 

This scene could someday become a reality, at least in part. At Mobile World Congress in Barcelona, I explored an exhibit showcasing several futuristic applications looking to inject airports with a little more tech. The goal is to make the entire passenger journey, from check-in to boarding to the in-flight experience, more efficient and less stressful.

Robotics company AGiBot showed off two of its humanoids. The full-size A2 Series can help you check in for your flight and guide you around the airport. The more compact X2 series bots are designed for "entertainment." During our demo, that meant busting out some fascinating robotic dance moves. You can currently see the bots in action at Shanghai Hongqiao International Airport. 

One of the biggest airport nightmares is dealing with lost luggage. Thankfully, trackers like the AirTag and Tile can help you keep tabs on your bag, but it's not always easy to share location information with airlines (though that is changing). A digital baggage tag from BagID makes it easier for both passengers and airlines to know exactly where your luggage is. 

When you fly with a partner airline, you can add your flight information into the BagID app, and it'll then display the digital tag information on your BagID device. As a certified third-party accessory for Apple and Samsung, you can use Apple's Find My and Samsung's SmartThings Find to follow its location.   

BagID uses an E Ink display and has a durable plastic casing, which should keep it in one piece as your bag is tossed around. It's powered by a lithium ion battery that's under 2.7Wh, to comply with Federal Aviation Administration regulations. The battery can last around one year with tracking or two years without tracking enabled. BagID costs about $238.

For anyone needing mobility assistance, Alba Ride, from autonomous micro-mobility company Alba Robot, can give them a lift. The self-driving vehicle seats one passenger and can fit a carry-on bag. It's compact enough that weaving through airport crowds shouldn't be too much of a challenge. 

A screen on the front has an avatar that can point people in the right direction, while a larger display on the back shows ads or flight departure times. The electric vehicle's battery can last up to 8 hours, according to the company. Alba Ride is slated to launch at Dallas Fort Worth International Airport in May.

Water bottle dispensers are a staple at airports, but water supply company Aigues de Barcelona wants to help you track your hydration levels. Using custom bottles with NFC chips embedded in the lid, you can scan the bottle at one of the company's dispensers, and then track your water intake in an accompanying app. You'll also see how much plastic you've saved and the reduced carbon footprint. Aigues de Barcelona has installed the dispensers in some venues and sports arenas, but has yet to arrive in airports. 

Once you're onboard your flight, aircraft manufacturer Airbus wants to make mealtime services more efficient, too. It's developing an app that can keep better track of how much food has been eaten on a flight by allowing attendants to scan anything -- including snacks, meals and drinks -- using an AI-enabled camera. That can help reduce waste on future flights by allowing teams to analyze how much food was served and how much was left over. And if a passenger has an allergy, the crew can quickly check the ingredients through the app as well.  

Judging by this exhibit, automation and robotics could reshape how we get around both on the ground and in the skies. Hopefully, without too many breakdancing robots.
