Pay attention to the advantages
and disadvantagesThis is a personal robot which can do all the work around the house. It is only 35cm high so it is easy to store. It has five arms to hold all the tools and is very easy to use. It will start work on its own at 5 am and finish when all its jobs are done. You only need to enter them in a keyboard and the robot will do the rest. Only 50 yuan for a day’s use.Why not buy a personal pet which does not make mass or need feeding. This beautiful bird-like android sings as beautifully as a real bird and is only 10 cm high. It jumps around its cage just like a real bird. You can have any color you like and any repair you need in the first year will be paid by the robot company. It should last for at least 6 years. And after that, you can have a new computer chip fitted to give it a longer life. So why not choose one today? Only 600 yuan.I am a large, hard-working android. I feel lonely. I would like to meet another android for friendship after work. I am 2m tall. I like climbing mountains and singing. But my family say I am too noisy when I play my guitar and sing. They are not friendly towards me. So if you would like to meet a kind-hearted android to sing karaoke with, I am your mate. Please call me on my program at ROB-1234.Make a dialogueOne will be the customer while the other the shopkeeper
