Tell us briefly about your project. Is it a work of art or does it serve another function?

Our project consists of a personal robot which could help in the homecare sector. The result is a homecare robot called Eva. Eva is designed and built by a group of six bachelor students who are from four different studies. The project was part of the Minor Robotics at the TU Delft. The goal was to build a personal robot for which a suitable application had to be found. After a trend analysis we had chosen for the home care sector. After that we interviewed 200 homecare-professionals to discover which tasked the robot had and had not to full fill. Based on these results we designed Eva to help people on an interactive effective way to help them with simple tasks in the household.

When did you start working on this project and how long did it take you to complete?

We started this project in September 2011. We didn’t have any knowledge of robotics, so we first had some introduction projects. After that we started in October with the design of our robot and in November we started building the robot. The robot was completely finished end of January.

What was your goal in building this project?

Our goal was to build a affordable robot which could serve in the homecare sector.

Does your project help to solve a problem? If so what problem?

Our project can solve a big problem in the future. With the growing rate of elderly worldwide, home care professionals have to divide their time over more clients. They spend a lot of time on practical tasks such as fetching and bringing around objects, limiting the amount of time they can spend on a more social support level. A robot could take over these practical tasks to provide humans with more time to spend on a personal level with their clients.

What makes your idea unique?

Our idea is unique because it shows that it is possible to make affordable robots in a short period of time which can be used in the homecare sector.

In what capacity are you using bearings and what type of bearings?

The most bearings we used are part of the arm, but we also used bearings in other parts of the robot. In the drivetrain of the front wheels we used ball bearings. To look at people we designed a pan and tilt mechanism, for each movement we used a ball bearing. Each pivot point of the arm consists at least of two ball bearings. The shoulder consists of 3 ball bearings in a row because there is an axle in axle mechanism. The most ball bearings of the arm are in the gripper. These are all ball bearings which are very small, but these are essential to ensure that the gripper moves smoothly.

What is the most important thing you want people to know about your project?

Our goal was to build a complete robot which could do many things. It looked impossible, but if you are with the right people and everybody has the right motivation, you can reach your goal.

How will you use the $5,000 prize?

We are all very excited to build a second version of this robot, because we see a lot of opportunities and improvements. So we will use the $10,000 to make a second version of our robot.
