Airplane Passenger Service Robot

A method comprising:

• operating a robotic system on a surface in an environment, wherein the robotic system includes (i) a housing having a first surface, (ii) one or more sensors coupled to the housing, (iii) a first wheel and a second wheel coupled to and extending away from the first surface of the housing, and (iv) a motor configured to drive at least one of the first wheel and the second wheel;
• detecting, using the one or more sensors, an object approaching the robotic system and responsively controlling the motor to cause the robotic system to cease movement;
• and
• retracting the first wheel and the second wheel into the housing such that the first surface of the housing is substantially flush with the surface within the environment.

A non-transitory computer-readable medium having stored thereon instructions, that when executed by one or more processors, cause a robotic system to perform operations comprising:

• operating a robotic system on a surface in an environment, wherein the robotic system includes (i) a housing having a first surface, (ii) one or more sensors coupled to the housing, (iii) a first wheel and a second wheel coupled to and extending away from the first surface of the housing, and (iv) a motor configured to drive at least one of the first wheel and the second wheel;
• detecting, using the one or more sensors, an object approaching the robotic system and responsively controlling the motor to cause the robotic system to cease movement;
• and
• retracting the first wheel and the second wheel into the housing such that the first surface of the housing is substantially flush with the surface within the environment.
