Meet Cyber Heart :3
 
Cyber Heart is a robot pony, created to be a servant pony, although she was proven to not be very good at her job, which resulted in her being let go and abandoned.  
Despite being a robot, she was given feelings too, and this made her sad and gave her self-confidence issues :c  
She might be clumsy, but she tries her best to help.
 
Cyber was then found out by Doctor Whooves, and he and Derpy had taken care of her, and helped treat her with respect and treat her like a normal pony.
 
She is currently working in Canterlot, where she is helped used to teach others about robotics and science, and also at the Doctor/Derpy residence, where she is used as help around the house :3
 
She has various tools and gadgets in her body, and also has access to a near endless supply of electricity.
