MegaRoi Posted January 20, 2018 Posted January 20, 2018 (edited) Finally I have an entry for TC13! Since TC12 was such a pleasure and an unthought success (thank you all), it is again big fun to enter this EB contest. I have bought two PullBack sets - just for the parts - two years ago, and the motors were laying in a box since then. To enter this contest, I had to find out which abilities the PBs have. Conclusion: it's heavy, has high speed but low torque, for a ridiculous short period of time, and stresses the parts around it a lot during wind up. But it's compact and doesn't need a BB. The first three weeks were just testing. I tried gearings, two PBs, escapement, gearboxes and so on. Nothing really satisfied me, while I don't want to build a car, but also nothing stationary. After at least fifteen revisions, this is where I ended up with: A Pull Back motor and a pile of parts ... good enough for a proof of concept. Edited January 21, 2018 by MegaRoi Quote
BrickbyBrickTechnic Posted January 20, 2018 Posted January 20, 2018 I'm unable to understand how this works... Quote
Aventador2004 Posted January 20, 2018 Posted January 20, 2018 Does it just drive? Or do the legs move? Quote

ThatOneBuilder Posted January 21, 2018 Posted January 21, 2018 This seems rather interesting, although on first look it really did seem like a pile of random parts haha! Quote
MegaRoi Posted January 21, 2018 Author Posted January 21, 2018 Thank you for your comments about my ... well, pile of parts. It doesn't look like, but I was building for two weeks on it. And I have to apologize for being too excited, but I think I got the contest fever yesterday. It was late, when I opened this topic with almost nothing. I will show photos soon. Quote
MegaRoi Posted January 21, 2018 Author Posted January 21, 2018 The Tiger Pull Bug It is powered by a single PB and has the normal behavior, pull back and release. The main mechanics can really walk on six legs. But only a few steps with one PB and almost none with two, while two of them were to heavy to be lifted by themselves. To increase playability, I found a compromise where its rolling on wheels, but still touching the ground with the legs, creating an intimidating sound. This solution also allows the additional weight of a shaped shell. I used isolation tape to create the stripes. The more I look at the pictures, the more I think I have to do them again ... It's builded modular, so it can be easily opened to have a look at the leg mechanics and the PB motor. To create the uniform leg movement in the video, I can change the rear axle against a PF driven one. The PB is still installed, so only forward is an option ... I hope you like it. Quote
mocbuild101 Posted January 21, 2018 Posted January 21, 2018 That looks great! I really like the PF motorization option. Quote

I really like the PF motorization option. Thank you too. It's not really an option, the PF can only be attached for demonstration. 58 minutes ago, Aventador2004 said: Nice! Video soon? Thank you very much! I'm fighting with the video at the moment. Maybe a teaser ... Quote

(even after the pro trial expires) Oh, yeah, I didn't see that before... I'm using Cute Cut on my iPad. It's not as precise as on a mouse based PC, but mine broke down a few months ago, and I have to be mobile at the moment. It works quite okay for me, but thanks for the hint. I've never created a video snippet before TC12, so that's a general problem of mine. I'm using my mobile without a tripod and it's hard for me to catch some good scenes that look also good in a video and present what I want to show. I think I can finish my entry video in the next two or three days. Meanwhile I have some more shots: And for those who like teasers (I don't), a really short video, that will give you a small view to the complete entry video. Quote
lcvisser Posted January 22, 2018 Posted January 22, 2018 Very original, I like it. I love how people are trying really hard to not build a car for this contest! Quote
JonathanM Posted January 22, 2018 Posted January 22, 2018 This turned out great! Very original. The stickers really add to it as well. Look forward to the final video :) Quote

Look forward to the final video :) Thank you for your comment. I'm not absolutely happy about the stickers. Before I was using a foil, this time isolation tape, which doesn't adhere very well. The video is almost done, just a few seconds are missing ... two more days ... And I need better entry photos ... Edited January 22, 2018 by MegaRoi photo, not foto ... Quote
Didumos69 Posted January 23, 2018 Posted January 23, 2018 (edited) Great entry! Nice to see a non-vehicle model. And excellently executed. Are you sure the custom stickers are allowed? Edited January 23, 2018 by Didumos69 Quote

Frequenzberater Posted January 23, 2018 Posted January 23, 2018 Nice! Reminds me of the "Motobug" from Sonic the Hedgehog :D Quote
MegaRoi Posted January 23, 2018 Author Posted January 23, 2018 Yippee! I'm done. I've entered this contest much earlier than I thought. First I thought I couldn't make it in time, because of the holidays. But then, the deadline was extended, so there was enough time to get the things packed. I have new photos for my entry: And finally the video: I hope you still like it. Btw: did someone noticed, that the two black bionicle tooth are not black, but taped transparent ones? Quote
JonathanM Posted January 23, 2018 Posted January 23, 2018 Ha, I love how it scurries across the table! Great work! Quote
shadow_elenter Posted January 24, 2018 Posted January 24, 2018 I love it man! very original! (and it's in my favorite LEGO colors) Quote
