Mechatronic Engineering incorporates deciplines from
-Computer Engineeering
-Electrical Engineering
-Mechanical Engineering
so its a good mix of all three engineering courses.
the way i see it is, if u complete the mechatronics course you will have a sound understnading of all 3 engineering courses and so can enter any of the 3 fields after uni.
admittadly u wont be as well a trained as someone who did that courses singularly, but it opens doors..
the main job aspects are robots of all kinds, manufacturing lines etc
