    If you have ever been disappointed because you don’t have a good gardener, the clever robot may one day become the helper of your indoor plants.

The Hexa Plant is a six-legged robot that has been specially made to care for the potted (盆栽的) plant that it carries on top of its head. Using light and heat sensors (传感器), the robot has the ability to carry its plant in and out of the daylight. If the houseplant needs more sun, the Hexa will walk into the sunlight; and if the houseplant is getting too hot, the Hexa will go back into the area that blocks direct light. The Hexa Plant will even do a little dance when it senses that the plant needs to be watered to warn its owner.

The robot was developed by Vincross engineer and founder Sun Tianqi after he saw a dead sunflower sitting in the darkness in a room back in 2014. “Plants only receive an action without responding,” Sun Tianqi wrote in a blog post. “Whether they are being cut, bitten, burned or pulled from the earth, or when they haven’t received enough sunshine, water, or are too hot or cold, they will hold still and take whatever is happening to them.”

According to Sun Tianqi, for billions of years, plants have never experienced movement of any kind, not even the simplest movement. In their whole lives, they stick to where they were born. Sun Tianqi continued, “Do they want to break their own settings or have a tendency (趋向) towards this? I do not know the answer, but I would love to try to share some of this human tendency and technology with plants. With the help of the robot, plants can experience the move.”

The Hexa Plant model robots are not for sale, though Vincross does sell a Hexa robot model. It is said that in the near future the robots can open up a new market to watch over our household plants.
