Petoi Camp

I'm working on a set of "armour" to make Bittle look like Transformers Ravage. Initially I wanted to replace all of Bittle's parts, but I was unable to disassemble the legs, and I'm not sure the main body can be disassembled without risk of breaking, so I built around the legs using the leg clip that I posted earlier, and I'll just repaint the body. So far each part is taking one day to engineer and model. Do the elbow servos need much ventilation? My replacement forearms cover the sides of the servo completely, only the top and bottom are open. I plan on only carrying it on my shoulder to a comic con and having it do light animations for an hour. The model files will be for sale in a month or two, but I will also share some parts for free on Printables.com, like the paws.

    Hello everyone, I'm using the following program to play with Nybble. I'm using the ultrasonic sensor (RUS 04, I think) and the Grove touch sensor, which work well in standard mode. I'm wondering if I could also integrate the Grove gesture sensor? If so, how should I integrate it into the existing program (in standard mode)? Best regards (:

When I first saw Petoi’s Bittle robot and all that could be done to modify it, I knew right then and there I wanted to turn it into a dinosaur. It's been a little over a year now since I got my Bittle and I have to say this modification is a dream come true for me. Growing up, I always had a love for robots but there were never real robots commercially available. Sure, we have the toys that were remote controlled that had wheels on the bottom of their feet but it just wasn’t the same thing. Now that we finally live in a time where robots are so much more complex and commercially available. It really was a dream come true to get a Petoi Bittle The fact that you have the option to build your own Bittle as a kit was a really cool way to encourage creativity like this. When I first saw how open ended the kit was it felt like it was screaming “please modify me.” When I first saw Bittle I thought it was the perfect baseline quadrilateral robot that I could do anything with. Now I don’t have anything against cats or dogs, I wanna make that clear. I think they are great but dinosaurs are just on another level. Seriously, who doesn't want a actual robot dinosaur? Modeling the head was a bit tricky; trying to model a hollowed out robotic triceratops skull so that it can fit over a servo is no easy task. Thankfully, I was able to use the dog head that came with the kit as a guide. It helped me double check measurements, and was the perfect design guideline to follow.  The tail was equally as tricky due to the lack of a rear-end servo to connect to. Thankfully, I was able to utilize the rear-end bar that was within the pelvic area on the body. From there I added a mini hook attachment and 2 prongs that slid inside the rear-end of the body for extra anchoring.  When I first attached the tail and let it walk around I knew an articulated tail might throw the robot off balance so I kept the design as a solid piece and let it act more as a back weight that kept the robot in line as it walked. There are some movement limitations that come with this mod but the extra weight in the tail and head gives the legs a bit more traction when walking. Before I leave you I just want to thank the team at Petoi for all the encouragement they gave as I finalized my dinosaur mod.
