Hi everyone, AREM2326 here with my entry to Sprinkle Otter’s sumo challenge, introducing Bombur! Weighing in at roughly 2lbs 11oz, and measuring 10.25 inches long, 9.25 inches wide and 5.25 inches tall, he is below average size for a sumo. Do not be deceived by his small size though, this powerful robot can push over 3 times his own weight! His massive amount of torque coupled with his virtually unstoppable flipper make a formidable opponent for any sumo robot! To find out more about him just click “ADDITIONAL INFORMATION” below!

After being absent from the community for a while I am finally back. A lot of school work was taking up a ton of my time and I haven’t had time to build or post any robots. Now I’m no longer inactive and will hopefully post something about every week. So here is my EV3 LIFT. It is one of my favourite projects since it was able to function perfectly without any errors after the programming was easily completed. This robot is mainly controlled by the two large motors and the touch sensor. (The center brick button is used in the reset function.) This project was inspired by norama’s (RCX) Lift. A very complex and amazing project that I’ve always been awed by. This lift is a lot more simpler than that one but functions very well. norama’s lift was more like an elevator, my lift is more like an old mine lift that lowers materials down into the tunnels and is meant to look like that as well. The touch sensor is used to lower the lift slowly (25% power) to the ground. When it is pressed the two motors start lowering the lift. The two motors of course have to spin in the same direction at the same speed to work correctly. They Also spin a little part on the side that shows that the motors are moving and so that you can see that the motors are going in the correct direction and not changing direction as they will if there isn’t enough string. When the load reaches the bottom and the touch sensor is released the program ends. However there is a myBlock called “ResetStop” that can be run in the program or after the program. When the center brick button is pressed it raises the lift back up. “ResetStop” can be included in the program or be left as a separate program to run. The program is quite simple. I won’t explain it because if it is uploaded successfully it shouldn’t be difficult to figure out. I’m sorry but I will not be posting an LDD file for this project since I would like to quickly move on to creating an EV3 remote for my NXT Claw Tank.

EV3 Robogator


Uploaded 4/16/2014

This robot I have made was inspired by the nxt version of robogator

Motor B follows Motor A in positive or negative Degrees. I needed a way to manualy tune-in a motor, in degrees. My searches found no usefull examples. . I had to create this block myself. I think this can help anyone needing a starting point, to improve upon. I hope the .ev3 gets published with this.

This, i believe, is the biggest, most complex, and most beautiful lego robotic hand ever. I have finished building the main thing, the palm and fingers, but I want to make it so it can stand by itself. It features the EV3 and NXT, hence the name. SuperHand explains itself also. This hand is over a foot from wrist to fingertips, and also just over a foot from end of thumb to the left side of the hand. That is HUGE. I will not reveal too much information yet, wait for the full project! Be patient!
