Abstract [en]

The advent of robotics and automation leaves few industries untouched. Today, robots assist in everything between production lines at automotive manufacturing plants to home cleaning. One area that remains relatively untouched by robotics however, is the restaurant industry. The purpose of this bachelor’s thesis was to develop a prototype designed to assist with one of the tasks a restaurant waiter faces - food delivery.

In order to accomplish this the robot must be able to drive and navigate in a restaurant environment and deliver food, all the while communicating with both restaurant staff and guests.

The project resulted in a differentially steered robot that navigates using infrared, radio-frequency identification and ultrasonic modules. An elevator mechanism was devised to present the food to the guests. The user interface consists of a screen and a keypad.

The prototype was tested successfully on an oval track measuring 3 by 1 meters. The tests showed that such a robot could likely be implemented in most restaurant settings.

Abstract [sv]

Tillkomsten av robotik och automatisering lämnar få industrier orörda. Idag assisterar robotar i allt från produktionslinjer på bilfabriker till hemstädning. Ett område som fortfarande är relativt orört av robotik är dock restaurangbranschen. Således var syftet med detta kandidatexamenarbete att utveckla en prototyp avsedd för att hjälpa till med en av de uppgifter som en restaurangservitör har - leverans av mat.

För att uppnå detta måste roboten kunna köra och navigera i en restaurangmiljö och leverera mat, samtidigt som den kommunicerar med både restaurangpersonal och gäster.

Projektet resulterade i en differentialstyrd robot som navigerar med hjälp av infraröd-, radiofrekvensidentifierings och ultraljudsmoduler. En hissmekanism konstruerades för att presentera maten för gästerna. Användargränssnittet bestod av en skärm och en knappsats.

Prototypen testades framgångsrikt på en oval bana som mäter 3 gånger 1 meter. Testerna visade att en sådan robot troligtvis skulle kunna implementeras i de flesta restaurangmiljöerna.
