The Jetsons in 1962 sold a dream to many people about Rosie the Robot – a sweet and caring robot that takes care of all household chores. Just imagine how easy life will be if you don’t have to spend your precious weekends washing piles of dishes, doing laundry or cleaning toilet bowls. More than 50 years have passed and Rosie the robot still remains a dream. Despite exponential growth of technology in recent years, many experts believe that robots which can perform many tasks such as household chores will not become reality anytime soon. 
One of the closet robots to Rosie the Robot that we have today is Roomba. Introduced by iRobot in 2015, Roomba 980 has intelligence navigation capability based on VSLAM (Vision Simultaneous Localization and Mapping) and wireless integration with smartphone app. 
In previous version before Roomba 980, the machine moves randomly and relied mainly on sensor to change direction before steps or to avoid obstacles. The new device is equipped with a camera that captures images of a room and a software to map out surrounding environment over time. The map is used to make sure that Roomba cleans the room properly in the most efficient route and enable the machine to go back to charging station by itself when the battery is low. It also has sensor to recognize the floor surface such as carpet and adjust its power accordingly . The integration with phone app offers extra benefits. It allows users to set cleaning level and timing for Roomba – which means that the device will do the work even when you are not at home.
Roomba is one of the first household devices that truly utilizes artificial intelligence and machine learning. Though the technology of simultaneous location and mapping (SLAM) has been around for many years, it was not an easy task to commercialize it given large computing power required. Being able to embed a computer system into a small device at affordable pricing ($899) has differentiated iRobot among its competitors .
Going rapidly from revenue of $299M in 2010 to $617M in 2015 , iRobot continues facing challenges to innovate and stay relevant in the market:
- Privacy: Together with camera and internet connection capability, there is a growing concern of privacy issue among users. Currently, iRobot addresses this concern by using a low resolution camera and the map is deleted after Roomba finishes cleaning a room. However, with long term memory, Roomba can classify and remember if an obstacle is permanent and temporary and knows what will be the fastest way to clean up a room. In addition, a house map can be shared across multiple devices in the future to coordinate and optimize processes. It’s a constant trade-off between efficiency and privacy that iRobot has to take into consideration.
- Affordability: The current pricing of ˜$900 for a vacuum cleaning robot is expensive when benchmarking with a typical vacuum cleaner of $200-300. To continue expand their market and capture more share, iRobot has to improve their technology while reduce cost to remain competitive in a globalized market.
- Functionality: Colin Angle, CEO of iRobot articulated a vision of “not so distant future, when your whole home is a robot” . IRobot has expanded their products from vacuum cleaning to mopping and outdoor cleaning, however it still targets only a small set of activities in the household. Expanding their product portfolio to address multiple areas will require a technology breakthrough for iRobot.
A future where human is free from cooking, washing and cleaning is hopefully not-so-distant for us and players such as iRobot is playing an active role to bring that future closer.
