quickwrite robot servant

If I had a robot servant I would have it be able to assist me with doing curtain chores like being able to wash the roof of my house or be able to easily change my mothers cars tire so she would not have to deal with possibly getting hurt by the weight of the vehicle. It would also be a defense robot so I wouldn't get mugged or injured. It would have heavy armor for stopping peoples attacks and it would be the color blue so my family would know it's my robot. I would also add an airsoft rifle so attackers would get the idea not to get to close.
