Information About Teacher

Professor Eke is, over all, a good fast paced teacher. 

Eke teaches various aspects of computer programming software with the assumption that you already know how to program well (due to the prerequisites). 

Eke's grading system should be talked about during the semester. Sometimes difficult to tell what grade we are getting until the end of the class. 

Eke assigns a small number of homework problems (some out of the book some not), but does not collect the homework. 

Eke's exams are usually difficult, frequently containing trick questions, and are usually based on in class work and labs. 

The Boe-Bot assignments that Eke gives out are difficult, so make sure to allot enough time to complete them. 

Eke has a way of getting students to perform at a level I never thought possible. 

I have gained more experience and have gotten more out of this class then any other class I have ever been in. 

Introduction to Numerical Methods with MATLAB is required and is referred to frequently for the first two months of class.

Roboto's Project

Synopsis

The goal of this project was to have Boe-Bot 1 travel to a rotating platform and pick a Lego off of the platform. Having retrieved the Lego, Bot 1 moves to an exchange zone where Boe-Bot 2 is waiting. In the exchange zone Bot 1 exchanges the Lego with Bot 2, so that Bot 2 can then take the Lego to a drop off point. Once Bot 2 reaches the drop off point it stacks the lego on top of other Legos and returns back to the exchange zone so that this procedure can occur two more times.
