Today, we are trying to make Steve’s ultrasound sensor work more proficiently. We also updated the code so it would go straight without the use of sensors. Chuck was proud of his magic numbers. The magic numbers stand for motor speeds which are 135, and 170. After our first test, we could see that Steve was maneuvering in a pretty straight line. We then tried drawing again, but we apparently could not go straight. So, we tested the wheels again and we realized we were off with the rotation by 0.1 seconds. After more tests, we haphazardly drew a couple stars. Sadly, we want triangles, not stars. Now, we took a step down to drawing circles. After more tests, we started to draw shapes that resemble triangles.
Today, we were given a basic agenda. We were told to have a code in our program that could move forward, turn right, turn left, and stop. Chuck has been working on this all class. Ron attached the sensors to Steve so now he can know where he is going by using readings from the infrared and ultrasound sensors. I, Bobzawald, had to write the general code for drawing a square on the board for all to see and I did it successfully. In the end, we completed our assignment very well. We shall post more videos of Steve quite soon.

Today we attempted to draw our triangle. When we took it out of the box, there were several motor connection problems, but Ron and Chuck were able to fix them so we we were able to continue with the drawing. After the first couple times, Steve drew a neat abstract drawing which drew acclaim since it was reproducible. We are very proud of our achievement, but it is not what we are trying to achieve. Let’s, go Steve!
Over the last couple days, we realized our robot Steve did not work. Ron will now test the shield on another robot while Chuck is making the code for controlling the Pwm since we will not be using wheel encoders. Ron is testing the shield by using a digital multimeter. To control our Pwm completely, we must find the circumference of the wheels. We used the formula for the circumference of a circle which is pi x diameter. We used a ruler to estimate the tire’s diameter and it was about 6.5 centimeters. After we plugged 6.5 into the formula we found the circumference which is approximately 20.4 centimeters. Apparently, our robot does not work, but Ron has no idea why. We then discussed our project for our other class while Ron decided to take his shield home and remake it. Charles was successful in making the theory of the code, and then him and the other Programmers put it into the robot to test the code. We then ran out of time, so we could not finish the code. That was today’s work!
Hello fellow bloggers,
Sorry for my extended absence, but Bobzawald is back and ready for business. I was sick last week, but now I will be ready to update what we are doing in our class. For today, Ron is inspecting the robot, making sure it is ready to make some robotic art. Chuck is waiting for Ron to finish inspecting the robot, so he an work on the programming. In our other class, we had to make an algorithm for making our shape, and here are our first set of steps.

Steve is in the final stages of development and only has a few things here and there to fix.
Steve is getting ready for a big assignment. The robot needs to draw a line in order to impress people from FAU.
Everything’s been going very well. Steve is now capable of drawing! Charles is just putting on the finishing touches on the code.
He’s coding outside.
Even though we did not have any robot building last week, we still had our theory class. In our theory class, we were preparing for our midterm exam which is 14/3/2012. We reviewed current, voltage, ultrasound sensors, motors, infrared sensors, and power dissipation. We all hope we do good on our exam, and we all think we will. Thank you for reading.
Hello People, Team Meet Steve has not made a submission more a while because our student teacher was not here to help us build our robots, so we had a slight break from building our robots. But here we are again, building our robots, and we have been broken into our teams once again by assignment. I, Bobzawald, am updating this wonderful blog, Ron is keeping up his progress with his making of the shield and Chuck is still working on our code for the Tri-Force of Courage. We won’t make any posts next week due to the fact that we will have spring break.
A brief explanation on ultrasound waves, one of the ways Steve is able to see.
