The simple explanation:

AMR = Autonomous Mobile Robot

An AMR is a smart, self-navigating Ai robot that can move around an environment without needing direct human control or Semi automatic which needs human control. It uses sensors (cameras, ultrasonic sensors, LIDAR, etc.) and onboard software to:

• Understand its surroundings
• Avoid obstacles
• Follow a planned route
• Carry or move objects safely

In the context of valet parking

A vehicle-moving AMR (like AutoMoverBot) is a robot designed specifically to:

• Drive underneath a car
• Lift it
• Move it through the parking lot
• Park it in a designated spot
• Retrieve the vehicle when needed

All without the keys, which dramatically improves security.

Why valet businesses like AMRs

• Prevent vehicle theft (staff never holds the keys)
• Reduce accidents caused by human drivers
• Increase parking capacity (AMRs can pack cars closer together)
• Cut staffing costs

How a Vehicle-Moving AMR (Like AutoMoverBot) Works

1. Positioning Under the Car
   • The robot is driven (or remotely controlled) so it aligns itself cleanly under the vehicle — typically right below the car’s wheels.
   • Because the AutoMoverBot is compact (about 2.1 m long × 1.1 m wide × 0.115 m tall) it can slide underneath most passenger cars.
   • It needs a minimum ground clearance of around 11.5 cm, so very low cars might be a challenge.
2. Clamping / Lifting Mechanism
   • Once in position, the robot uses a lifting motor to raise parts of the vehicle. According to their specs, the AMB car mover version has a lifting height of 115 mm.
   • It “clamps” or grips the car at specific points to secure it before lifting and moving. According to the AutoMoverBot website, it has “one-click clamping” built into the process.
   • There’s also a laser collision prevention system so the robot can detect if something (or someone) is too close and avoid dangerous collisions.
3. Mobility & Navigation
   • The robot drives on its own using wheels. It’s powered by a driving motor (in the AMB versions, DC 1500 W) and a battery.
   • Max speed is about 1 m/s for the robot.
   • It uses Wi-Fi for remote control / communication, so an operator (or a system) can tell it where to go.
   • The robot can handle slight inclines (“climbing capacity”) because its design supports small gradients.
4. Safety Features
   • Because it’s partly autonomous, it has obstacle-detection sensors. That means the robot doesn’t blindly push into things — it can avoid collisions.
   • Electromagnetic braking is used, so it can stop reliably. In one AMB model, the braking type is listed as electromagnetic braking.
   • The system has an app-based control interface. Operators use a mobile app to control and monitor the lifting, clamping, moving, and unloading of the car.
5. Payload / Capacity
   • The AutoMoverBot AMR is rated for cars up to ~3.0 tonnes (max load) per its product page.
   • It supports a variety of car dimensions: up to ~5.5 m in length (for certain versions), maximum width of ~2.05 m (excluding mirrors).
6. Power / Battery
   • The robot runs on batteries (for the AMB mover version: 2x 12 V / 210 Ah).
   • Charging is done via a charger (e.g. 24V / 30 A for AMB).
   • When battery goes under a certain threshold, you need to recharge.
7. Load & Unload Process
   • To load (i.e., pick up a car): after positioning, you press a “load” button (on the app or robot) and the clamping + lift sequence begins.
   • To unload (i.e., drop the car off): there’s a similar “unload” command; the robot lowers the vehicle and releases its grip.
   • If something goes wrong, there’s a reset function to stop and restart the procedure.

Real-World Use & Benefits (Related to How It Lifts)

• Because the robot grips and lifts at the wheels, it doesn’t need to lift the entire vehicle body, which is more efficient and safer.
• The lift height (115 mm for AMB) is enough to raise the wheels just enough to let the robot drive the car around. This kind of robot is very useful in tight parking environments, because it doesn’t need room for a human driver or turning space — it just slides under and carries the car where needed.
