Last week JS and I reconstructed our robot to become more stable. In the front we now have a plow with ultrasonic sensors behind it. We are still working on getting them to work properly so that the robot doesn’t fall off the edge of the (testing) table. Next we will work on how to use the “light” sensors. -JH 2/4/10

In STEM after school with Mr. Ray we are doing a couple of interesting things, we are building stuff with K’Nex and learning how to use snowshoes.


Most of the group that meets with Mr. Ray most Thursday’s.

I rock at Legos
I really work with Legos
Legos are so fun

Legos are too cool
Playing with Legos is cool
Legos are awesome

Having fun learning together happens easily with Lego-robotics. Students work with lego’s to identify simple machines, create battery-powered motorized lego constructions as well as program robots! It’s a great time to be together.

Robotics is a great experience. It is also a great place to learn and have fun. This year we are working on a competition using Lego’s. We have a variety of instruments to use and can have up to three motors and four sensors. For sensors we have ultrasonic (sensor sending ultrasonic waves and using the “echo’” to locate near objects, touch (which is a button that is easily pushed), light (which determines how dark or light as object is) and sound sensors (which can make the robot do something depending on the sound level). The motor is like an arm reaching for a doorknob. It has the motor where the “shoulder” would be and where the hand would be is the part that rotates forward and reverse. The base where you start from is the “computer” or what controls the motors and reacts with the sensors depending on how you programmed it. The programming is done on the computer and is transferred to the robot through the USB cable. Joe Schwartz and I have started ours using the ultrasonic sensor on the front of our robot facing down so that when its about to go ff of the edge of the playing field it stops, then backs up and turns before going again. We hope to do well in the competition. – JH
