Many elders does not have enough strength to lift up certain things and move it to other places. Others need an extra hand because one is occupied by a stick. So the Butler BOT will help those who need it, providing transport for drinks, food, pills, magazines, and so on. Also provides entertainment, a torch and a SOS button.
Future improvements, add a brush to clean the house while it moves and program a cleaning function. Because some people does not have the will to clean the house.
The functionality of this robot it's very wide, but the first idea is to make it work as an autonomous robot that will reach the owner by only activating one switch (RFID emitter). The other functions add some atractive to make it part of the day a day for the elders.
