Grass seeding robot Lego mindstorms EV3
pasquentmax posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hello everybody ! You want a perfect lawn ? to repair your lawn ? Use my grass seeding robot, the world’s first domestic robot that detects holes in the lawn and sows grass inside ! * The robot is autonomous, it has two modes of movement, a grid mode when it can come to bump against a fixed wall and canvass effectively with the gyroscope (this is the case in the video, zeroing at each contact with the terrace) or a random mode, basic vacuum cleaner style. * Bluetooth transmits an instant measure of lawn density in % (the 100% calibration being the dense lawn), the average density in % and the number of holes detected. At start-up the operator transmits a minimum hole size via bluetooth to be detected. (in % of the image size is 10 cm x 6 cm) * 3 Ev3 brains to do this project * It detects holes with a Pixy Cam 2 camera, scarifies (just for demo, not effectively, I didn’t equip it with metal spikes) and sows seeds in the hole. * In summary the final result, to discover in the video, is a robot with 6 motors: 4 motors of drive of the wheels mecanum, 1 motor for the control of the scarifier and a motor with endless screw for the distribution of seeds and 8 sensors: 1 gyrsocope, 2 ultrasonic, an IR, 2 contacts, 1 pixycam and a light detector for seed level. -
A replica of the solar porch on the front of my house. It's where all my LEGO MOCs have been photographed, so it has a special significance to my LEGO hobby: See more pictures on my website: http://www.brickbuilt.org/?p=3903 Thanks for looking, C&C appreciated.

[MINI] Lawn Tractor
Eraman posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hi everyone! My name is Eraman, i'm newbie here. This is my first contest, I'm very excited The idea of my mini lawn tractor came from my older creation. 2 months ago I built a bigger lawn tractor. I thought, it is enough good to try to publish on lego cusoo(lego ideas). https://ideas.lego.com/projects/62241 When I saw this contest, I knew, it will get a "little brother:)" Function: 1. Front wheel steering 2. Rotating blade 3. Openable hood It's not too much function, but it meets the requirments(i hope so ) Rather I tried to create a good-looking tractor. Number of parts: 200 pieces Dimension: length: 18-19 studs width: 9 studs (with wheels ~12studs) height: ~9studs Tyres: lego 42008 (43,2x22), 9390 (30,4x14) Some thoughts about the development: My vehicle was designed in LDD, I worked a lot on it. It's always being under development. Tomorrow I share my first LDD rendered pic and maybe the first real shot. Unfortunately I do not have all color of parts, what I imagined, but LDD pic will show my conception. If i have enough time, i will share some previous and coming problems/moments of the improvement. The promotional picture (black edition): More pic here! Part list: An LDD picture of the final version(green version): (All parts and their colours are official!) LDD file: ver.7.6final Building Instruction here Thanks for reading! ps: sorry for my poor english -
[MINI] Lawn and garden tractor
Pluto_MkII posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hey guys, I'm new here and would like to present you the WIP of my lawn and garden tractor. At the moment, it features RWD, a turning blade and a V2-Engine. Both are connected to the RWD, which has a differential. The seat is variable, it moves in one stud steps. The front wheels are steered by the small steering wheel. Things I'm having on my to do list at the moment: - I'll have to optimize the partcount to give the lawn and garden tractor a nice body (194 parts at the moment). - Building the model in real life (this will happen next weekend). And I have a picture of the actual virtual model for you, which shows the drivetrain and the frame. In the model above I made the wrong picture, so you can't see the steering. My second picture shows you my virtual model with body parts. I'll use silver and black or red and black. I'll see which plates I have at home and use them in one of the two colour combinations. The basket isn't ready, when playing with the lawn garden tractor the player can remove it. Another small update: I changed the body design, because the first version of the body was too "fat". -
