Chur-Robot

With little more than a budget of $250 and a dream a team of Olin students created a Chur-Robot capable of making sweet, crunchy churros. 

There are five major parts to the mechanical system: the extruder, the tip exchanger, the stirrer, the lifter and the shaker. Details on how the team built and tested these systems can be found here.  The software components run the Arduino and coordinates the motor movements. The final piece of the puzzle involved the electrical system

Although the team encountered some trouble with the dough and the tip exchanger, the end result did resemble a churro. So, sit back and enjoy.
