Description of the planting machine |
Costs |
1 |
The basis of the planting machine is the conveyer band described above – fix two wooden slats on the left and right side of the band – later we fix the planting parts on them |
0 € |
2 |
You need an NXT robot from Lego, a computer, 2-3 ultrasonic sensors, 3 motors and some Lego bricks to build some smaller tanks – you can buy a used NXT set including everything for less than 100 € on the internet – you get a DVD together with the Lego set >> it explains how to program the NXT and how to use sensors – it’s rather easy! You also find instructions/videos on the internet how to do it. |
80-150 € |
3 |
Build 3 Lego tanks with the bricks. At the bottom you need a hole (about 4x4 cm) which you can open and close with the motor – we used LEGO gear wheels(part of the set) to close and open the tanks – place everything above the band |
0-25 € |
4 |
Fix some big plastic bottles above your Lego tanks and slice them at the bottoms – later you fill them with potting compost and seeds |
0 € |
5 |
Write a program on your computer (we will put an example on our website) so that the motors react when the ultrasonic sensors recognize pots in front of themselves – now the compost/seeds should fall into the pots - work on the timing (e.g.: change the position of the sensor, the speed of the conveyer band or improve the program!) |
0 € |
6 |
At the end you can fix a used submerged pump which people sometimes use for ponds to water the pots – you can also control it with the NXT and use a sensor for the timing |
5-10 € |
7 |
Work on the perfect timing - the faster you can run it the more you can produce! |
0 € |
8 |
You could build a sliding board at the end to sort the pots |
0-10 € |
