ME 425/625 is an undergrad/graduate (senior/masters) level course introducing robotics.
This course will use the LEGO NXT Brick (i.e. a computer) and NxC programming language
with motors and sensors (i.e. control). The overall objective is to expose students to
the underlying mechanisms, electronics and algorithms needed to broadly appreciate
the field of robotics.
