Need some help on a lifting mechanism
Carsten Svendsen posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
I don't have much space to use and the servo motor needs to be lifted from the bottom and up totaling 90° radius. The servo needs to be lifted with pneumatics. I've built this model in SR3D Builder to show you guys. It's not really many pieces so anyone could build it IRL and try to make out something. It should be easily recreateable from the pictures. I'm pretty clueless and I don't know of that many different mechanical solutions with 4 different liftarms or so, so I'm asking for help in hopes that someone would help me -
My technic autonomous robots
AlmightyArjen posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hi! Didn't know this forum, pretty awesome! I want to show you my technic robots that I've built so far. Since I'm from the early 80's, I never got used to building with studless (although I see some advantages) so forgive me: the robots are all studded ;) Next to that: I love electronics and I love to design it myself so I'm using the Arduino platform instead of NXT to control my robots. For me it's more flexible (and cheaper). Plant watering robot This was an idea of a colleaque of mine when I was telling that I was building an autonomous rover (see below). He said to me: why don't you build something useful like a robot that takes care of the plants while you're on holiday! And an idea was born... See below the result :) Autonomous rover which returns to a charging station when battery runs low This one was a real hassle to get it work. The rover itself wasn't the problem, but to make it park into the charging station was tricky. But I pulled it off by a coded IR signal which tells the rover when to turn and drive into the station. It's built in a Classic Space theme with cool lights. Oh, and in the end of the video, the rover takes care of some evil space pirates ;) Light chasing autonomous rover Predecessor of the rover above: driven by NXT motors it was a "real rover" with wheels. Unfortunately it wasn't agile enough to make it park into a charging station... -
Pneumatic pressure testing.
Tclancey posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hi folks. I'm a new member to please forgive me if I'm in the wrong place... Just wondering if anyone has any advice on pressure testing the lego pneumatic systems. I'm building up some old models, I know I need to replace bits, but want to know which bits without going through hours of swapping them around. Also, what's the best advice for old pneumatic rams that are a bit 'lumpy', is there a safe way of lubricating internal seals? I've thought of a hyperdermic and thin motor oil, but don't want to use anything that's going to damage the plastic or o-rings. Any help gratefully received. -
