In this episode, Audrow Nash speaks to Helen Greiner, CEO at Tertill, which makes a small solar powered weeding robot for vegetable gardens. The conversation begins with an overview of Helen's previous robotics experience, including at as a student at MIT, Co-founder at iRobot, Founder and CEO at CyPhyWorks, and in advising government research in robotics, AI, and machine learning. From there, Helen explains the design of the Tertill robot, how it works, and her high hopes for this simple robot: to help reduce the environmental impact of the agriculture industry by helping people to grow their own food. In the last part of the conversation, Helen speaks broadly about her experience in robotics startups, the robotics industry, and the future of robotics.

"Fearless Girl should provide the spark to inspire more female engineers", writes Elizabeth Croft, Dean and Faculty of Engineering at Monash University. "Girls are natural engineers, highly capable in maths and physics. We need to show them that these tools can be used to design a better world.So far, we've done a poor job of communicating to girls the very powerful impact they can make through an engineering career." Croft continues, providing us with the inspiration to introduce the second of our new series of Women in Robotics Updates, featuring Elizabeth Croft, Helen Greiner and Heather Knight from our first "25 women in robotics you need to know about" list in 2013. There are 180 more stories on our 2013 to 2020 lists.

Helen Greiner, of US company iRobot Corp, is here promoting a carpet cleaning robot. They're small, unobstrusive, and seem happy to do a job few if any of us enjoy. Such is the appeal of iRobot Corporation's vacuum cleaner known as Roomba that the Massachusetts-based company has already sold more than a million of them in the US. Some, says iRobot chairwoman Helen Greiner, have been named. "Rosie is a highly popular (name) and so is Abby or Agnes," Ms Greiner says.
