Claims (7)

1. En golvsàg (100, 100a, 100b) innefattande en styrenhet (130) anordnad att automatiskt styra golvsàgen att säga längs en önskad linje, kännetecknad av att styrenheten (130) även är anordnad att bestämma huruvida en operatör är i position för att utföra manuell kontroll av golvsàgens styrning genom att ha sina händer pà ett kontrollhandtag (190) pà golvsägen, och att utlösa en varningssignal och/eller stoppa golvsägen som svar pà att det bestämts att en operatör inte är i position för att utföra manuell kontroll av golvsàgens styrning.
2. Golvsàgen (100, 100a, 100b) enligt patentkrav 1, varvid golvsägen innefattar en cirkulär sàgklinga (110) anordnad att vara förskjuten (O) tvärs en (C) är i framàtriktning (F), där golvsägen vidare innefattar àtminstone tvà stödhjul centrumlinje (C), vilken centrumlinje linje med golvsàgens (120, 120a, 120b) anordnade att uppbära golvsàgen pà betongytsegmentet (160), en sensoranordning (140) konfigurerad att bestämma en aktuell girrörelse för golvsägen, och en styrenhet (130) konfigurerad att erhälla en önskad inställning för girrörelsen, varvid àtminstone ett av stödhjulen (120, 120a, 120b) är anordnat pà en motsatt sida av centrumlinjen (C) jämfört med den cirkulära sàgklingan (110) och anordnat att generera en respektive variabel hjulkraft, och varvid styrenheten (130) är anordnad att styra en skillnad mellan hjulkrafterna hos stödhjulen för att minska en skillnad mellan golvsàgens aktuella girrörelse och den önskade inställningen för girrörelsen.
3. Golvsàgen (100, 100a, 100b) enligt patentkrav 2, varvid nämnda àtminstone tvà stödhjul (120, 120a, 120b) är drivna hjul, och varvid styrenheten (130) är anordnad att styra skillnaden mellan hjulkrafterna för stödhjulen genom att styra respektive hjulvridmoment och/eller hastigheter hos de àtminstone tvà drivna hjulen (120, 120a, 120b).
4. Golvsàgen (100, 100a, 100b) enligt nägot av föregàende patentkrav, innefattande ett första drivhjul (120a) och ett andra drivhjul (120b), där varje drivhjul drivs av en respektive första och andra elektrisk maskin (150a, 150b) styrd av styrenheten (130).
5. Golvsägen (100, 100a, 100b) enligt patentkrav 2, varvid styrenheten (130) är anordnad att ta emot den önskade inställningen för girrörelsen via tràdlös radiolänk (320) fràn en fjärrkontrollanordning (310).
6. Golvsägen (100, varvid fjärrkontrollanordningen 100a, 100b) (310) är konfigurerad att överföra en önskad enligt patentkrav 5, inställning för girrörelsen motsvarande sägning längs en rak linje, eller motsvarande sägning längs en bägformig kurva med en konfigurerbar radie, eller motsvarande en bana med en avvikelse definierad med ett antal grader fràn en inställd kurs efter en kontrollerad svängmanöver.
7. Golvsàgen (100, 100a, 100b) enligt patentkrav 5 eller 6, varvid fjärrkontrollanordningen (310) är konfigurerad att styra en eller flera ytterligare golvsàgar (100) utöver golvsàgen.
