P3NGUIN 2.0 is an upgrade to P3NGUIN. Some detail worthy to note are the little fingers above the flippers. The walking mechanism is the same (check out the original P3NGUIN for more detailed information). The legs are longer and the flipper-feet are also longer for stability. I tried to make sure that I didn’t make them too long; it needs to look like a penguin, right? The major improvement to P3NGUIN is that now, P3NGUIN 2.0 can walk on carpet AND smooth surfaces such as glass! In able to walk on slick desk, I put grip on the rear of the legs. The grips are taken off when walking on carpet. First video demonstrates P3NGUIN walking on carpet, and second video shows P3NGUIN walking on my desk. Keep a sharp lookout for my SumoBot! Enjoy.

P3NGUIN is another entry for EV3Community’s WalkingBot Challenge. P3NGUIN is a biped robot; he walks on just two legs. P3NGUIN is a very fast biped; I am pretty sure that he is faster than the official NXT Alpha Rex (1.0 + 2.0). Watch the video for yourself and tell me what you think. So you may be thinking, “What’s up with the main picture?” Penguins live in cold weather areas, right? (Most of them, anyway.) So I had P3NGUIN on “snow”. Yep, the marshmallows are big “snowballs”. I had to work on this robot for a little bit longer than I usually spend (on this sort of project). This robot walks with only one EV3 Large Motor.
The walking mechanism; let me explain it to you. The Large Motor drives forward at 100% power, turning 36z gears on both sides. Those turn a 12z gear which turn more 36z gears. One side of an angle beam attaches to the EV3 Brick, and the other side attaches to a hole on the bottom 36z gear. This cause the legs to move forward and backward, out and in, respectively. Please view the slideshow for clarification.
Thank you nxtstep101! Your robot, My Very First Biped, has inspired me to create this robot with which I am well pleased with. I’m thinking of including a slightly changed and improved P3NGUIN for The LEGO® MINDSTORMS® EV3LUTION.

SPRINT3R is one of my entries to EV3Community’s Walkingbot Challenge. I named it SPRINT3R because it is fast. It features four legs (or paddles, if you prefer that). This sort of reminds me of a turtle because of the big top. I programed it to sprint full speed ahead when the touch sensor is pressed, and to stop when pressed again. I have to say that this is not the best of its kind; it was built today due to boredom. But I am adequately satisfied with SPRINT3R. The legs were inspired by RoboGator; the difference is that both front AND back legs propel SPRINT3R. It reminds me of paddles. :) Watch the video to see SPRINT3R sprint across the floor. There is a free-spin wheel under SPRINT3R to ensure that the bottom doesn’t get caught on the surface it’s walking on or scratched up, also giving it a smooth ride. Look forward to my next robot, a walking penguin!
