some insight on team 1646 (since they're part of Purdue FIRST programs)
Their Robot
Problem is finding an updated picture. They have made many changes to their robot over the two regionals. They have modified their ball-pickup and added a shooting mechanism, which in all honesty, still needs some work.
On the other hand, they do have a great, reliable, and durable drive train. They are a decent defensive threat, and with some more work, they could become a reliable offensive component of an alliance.
