Project OverviewThe design project Wall-E Prototype I is an intelligent automated trash collecting robot with obstacle detection capability. The robot responses to either users direct manual control, or the object tracking software, to locate and collect the targeted trash object.

Project MotivationMotivated by the Wall-E pictured in the Disney Movie

The solution to the environmental threat caused by the huge amount of waste disposed by human society

The first version called Wall-E Prototype I
