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.
