Walking plant hexapod robot

update 5/16/2016

There is a display of the robots at the Contemporary Art Museum of St. Louis. http://camstl.org/ This was a very rewarding class that highlighted 3D printed robotics in Art. Go ahead build yourself a museum class robot.

This is a custom robot made for a a one time workshop for high school art students though a program found here. http://camstl.org/programs/youth-teen-programs/nan/

During the workshop we divided roughly 20 students up into 4 groups were each group built a walking robot.

Not shown is that a moisture sensor is attached to analog port 0 on the Light Blue bean.

Here is a Drop box link to the workshops build instruction and the program. The program is a bit rough but it will be a great starting point.

The robots are programmed to move towards light and to be an extension of the plant itself. They do this by moving towards sunlight and beeping when the moisture of the plant is low. This allows the robot to warn you when the plant needs water while keeping the plant in the sunlight longer than normal potted plant can. These robots are hexapod robots. For example, hexapod robots can step over various obstacles, like a book, that a wheeled robot can not.

The light sensor should be facing angled towards the front of the robot with a clear line of sight to work correctly
