I just got back from the MURC competition on the 18th of jan. the robot i built for the competition... "Sharp Tooth"... lost both of the 1 on 1 fights, and was knocked out fast in 12 pound rumble #2 , but i did have a wonderfull time meeting all the builders and seeing all the awesome robots.

I got a few comments about my unique weapon, it is a spinning disk powered spike that fires automatically when a robot is in the path of the weapon. it has the advantages of both kinds of weapons... high speed spinning power storage, and a directed penetrating output for all the force instead of a glancing blow. unfortunately it didn't work all that well. steering was a problem, and the arena floor was slippery, i was going for car style drive and steering, but it didn't work very well. next time i will do 2 wheel differential steering.

I did a lot of work on my robot at Jerome Miles's house. he really helped me out a bunch. His robot named "It Doesn't Matter" won a rumble and he got a trophy. I had a great time, the whole thing was awesome.

An update about the robot arm i built: It was SWEET! all the little kids loved it, all the adults were facinated. it was a total success! everyone that has seen it has thought it was amazing, as soon as I can figure out how to set up a linux server i will have some videos of the arm, and the competition to show all y''all!

I have over the past few day built a master/slave arm set. the master is 4 100k potentometers mounted on a frame to fit my arm, and wired into a joystick port. 2 pots in the shoulder give elevation, and rotation. 1 pot for the elbow. and one for the gripper. 4 sevos make up the arm, 1 coresponding directly to each potentometer, and making an arm that is roughly the same dimensions as my arm, and has nearly the same degree of freedom, though it is somewhat weak.

the interface is an ifi robotics issac16 setup, the operator interface takes joysticks as input, and gives a wireless link to the robot controller. the robot controller is a basic stamp 2 or something, and has 8 PWM outputs.

I am planning to use it to hand out candy for halloween.

I have finaly built a small remote controled robot with a griping arm. You can see details and pictures on my website. will most likely build a better chasis in the next few days.

I have been doing some research on computer vision systems and have a few ideas about how to use a digital camera to navigate and map an environment by overlapping pictures.

Made a small rc bot from 2 servos I modified(wheels), and one normal servo(verticle arm). I used a model plane remote and reciever I had sitting around to control it.

Got an ifi robotics controler and have done some design work on a continuously variable transmision for a battlebot
