Not quite to the same scale as @Pete J, but started my Lego off-roader. I got all the functional components completed so about 2/3rds of the build, just bodywork left to complete. Bluetooth set-up and started a bit of driving. Took a couple of hours in total. After a bit of a play, I made 50% of the available gear ratio changes to get more climbing power (at the cost of speed). More pictures here; https://imgur.com/gallery/LA5wwbA Thought some of you might enjoy it.
I was always fascinated with Technic suspension and steering linkages. I still remember building my first set with front suspension. Enjoy the build looks like a fun kit.
We have a guinea-pig called Boris, because of his daft floppy hair and being unfit to run the country. I prepped Laura when BoJo was in hospital, if he was to pass she was to tell me "the prime minister has died" so that I wouldn't get upset.
I'm still alive! I like this build - I have a soft spot for efficient space usage and this model does exactly that. How does the drive system work? I notice there are three motors - does this mean the front and rear wheels have independent drive?
Yeah, homage as in respect, rather than in memory. Possible inappropriate timing! Model is 958 pieces, so a lot of fidly bits. You are right, on the three motors. Two motors in the front assembly, one big driving the front wheels, the other smaller one is steering. Rear assemble has separate big motor driving the rear wheels. All the wheels have independent suspension and power transmission. It will climb over a 30mm vertical door step (approached at slight angle) and have done a 30 degree incline so far. The front assembly will rotate separately from the rear (where the battery pack is). So wheels get good contact over uneven surfaces.
Interesting to see how well you can integrate the lights into it! I wonder how the motors for the front and back keep up with each other? I know the new motor system has feedback monitoring, and a little variation isn't going to be noticed (it being a toy after all). Does it have a calibration procedure? For the steering, for example?
I then spent most of the afternoon playing with these. Yeah, there is some decent levels of sensors built in, it gives you climb / descent angle along with body roll info. There is a calibration process for steering, I think the motors feedback to balance / stop overloading. I spent more time wiring than I did the rest of the model. Then a random one where I think I moved during the photo! Not bad for 3AA batteries and a £18 eBay light kit!
