Conveyor System for Delta-Robot One

Welcome robot friends!

This is an additional system for Delta-Robot One. It is called conveyor system. Things for example metal chips can be transported into the robots workingspace to grasp and sort them in different areas. The conveyor system extents the Delta-Robot One project and provides the posability to do some new tasks. Be creative and do some cool things with it. In the future it is planned to extend the robot and conveyor system with an image processing platform based on a Raspberry Pi 3 board.

This repository provides all parts you need to build the conveyor system. Delta-Robot One and also this system are mainly designed for students and makers with an educational thought. The Conveyor System for Delta-Robot One is designed as a kit. The pluggable mechanical solution make the assembly fast and easy. Like Delta-Robot One this system is basicly build of lasercutted and 3D-printed parts. An introduction at the containing wiki provides a description of all parts including production files, drawings and a list where you can get the parts. If all the parts are produced and/or delivered the assembly steps will be described at the wiki page. The last step decribes the usage of the system with Delta-Robot One.

>>>Conveyor System Wiki<<<

With the help of a community (this means you) it could be a world wide educational project. Working on this project is a lot of fun. Learning something about the different topics and share it with the world is realy great. Be part of it...

This video clip show a Delta-Robot One with long pillars found at hardware parts and the Conveyor System.

We used a system like this to grasp some chips at the image processing lab of our university. We detect the chips, the colour and the velocity. In the video above you can see a simple system with no image processing. The chip is only detected by a time of flight sensor. The motor of the conveyor system and the sensor are both connected to the robots interface. This shows the possibility to extend your robot. There are interfaces provided for Gripper/GND (ON/OFF), Motor/GND (PWM max. 4A), I2C Bus (SCL/SDA), Power/GND (5V/max. 4A)

Conveyor System assembly

The Conveyor System for Delta-Robot One is designed as a kit. The pluggable mechanical solution make the assembly fast and easy. Choose the colours of some parts to give the system an individual look. All in all building this system provides you with a short practical, educational and interesting experience. Now it‘s time to build your own conveyor system!

How to build your conveyor? No worrys we create a wiki...

Lasercutting Parts

>>>Documentation<<<

>>>Files<<<

How to get the layers? There are many ways...

• You can use a lasercutter in a Techshop/Makerspace or your School/University

• We ordered from cutcraft a few times so we can recommend this service

• We don't try it but with a 3D-Printer it has to be possible to create the layers too

Be creative and choose your own design to build an individual Conveyor System.

All drawings of the layer system are availible...

How to get the parts? No problem...

How to get the parts? The only electric part are the DC-Motor...

There are two recommended types of motors:

Option 1: DC-Motor without encoder 12V 62RPM

Shoplink

Option 2: DC-Motor with encoder 12V 100RPM

Shoplink

It is recommended to use the Conveyor System with Delta-Robot One. There is an hardware interface for external motors like the drive of Conveyor System. The picture below shows the schematics of this hardware interface. All Schematics for Delta Robot-One are availible also in a fritzing version...

>>>Schematics<<<

Delta-Robot One has an hardware interface on the circuit board to provide the usage of the conveyor system without any additional hardware like a motordriver or a power supply. Connect the DC-Motor of Conveyor System to your Delta-Robot One interface to M+(PWM max. 5V/4A) and M-(GND).

Conveyor System and Arduino Library

(requires Delta-Robot One)

The Arduino Library for Delta-Robot One contains the code which provides the control of an external DC-Motor. So it is possible to use the conveyor system directl. If you would like to go more into detail you can do this without any problem because the software is open source.

Sourcecode: >>>One System Library<<<

We recommend to use the FullSystemDemo of OneSystemLibrary to do the first steps wit Delta-Robot One and Conveyor System. The basic functions to control the drive of Conveyor System are implemented in this demo. Use the menu of Delta-Robot One and navigate to Ext. Motor.

This function is controling an external motor connected to the pinout (M+, M-) of One Circuit Board (5V). Start and stop the motor by pressing the encoder button. Rotate the encoder to change the speed of the motor. Go back with center button.

In the next step you can write your own control function using the interface of OneSystemLibrary:

The following lines are showing the external motor example of the One System Library. Select this example at Arduino IDE to control Conveyor System.

//Create the DeltaRobotOne-Object
DeltaRobotOne robot(0, 0, 0, 0, 0, 0, 0x27);
void setup()
{ 
//Robot setup
robot.setup(); 
//Power main circuit
robot.power.mainOn();
//Move the robot to the home position (X=0.0,Y=0.0,Z=85.0)  
robot.move.ptp(home);
//Clear the display
robot.display.clear();
//Print out some information on display
robot.display.printLine1(F("External Motor"));
//Wait for 2 seconds
robot.functions.waitFor(2000);
}
void loop()
{
//This example shows you how to use an external motor on the robot interface
//Connect a DC-Motor to interface pins M+ (5V max) and M- (Ground)
//The motor speed can be set beetween 1 and 255
//Set a high motor speed
int speedValue = 255;
//Start the motor
// if you have a high motorspeed you can use this function in this way
robot.extmotor.start(speedValue);
//Wait for 2 seconds
robot.functions.waitFor(2000);
//Stop the motor
robot.extmotor.stop();
//Wait for 2 seconds
robot.functions.waitFor(2000);
//Set a slow motor speed
speedValue = 50;
//If you have a slow motorspeed you can use the startup parameter 
//to set a high speed for 500 milliseconds to start the motor
//Start the motor with startup function
robot.extmotor.start(speedValue,true);
//Wait for 2 seconds
robot.functions.waitFor(2000);
//Set a normal motor speed
speedValue = 150;
//Change the speed of the motor while the motor is running
robot.extmotor.setSpeed(speedValue);
//Wait for 2 seconds
robot.functions.waitFor(2000);
//Stop the motor
robot.extmotor.stop();
//Wait for 2 seconds
robot.functions.waitFor(2000);
}

Python package one-easy-protocol

(requires Delta-Robot One)

A Python package provides the communication protocol with a high level interface to control Delta-Robot One from other systems. So you can control the robot and/or the Conveyor System easily from a system like a Raspberry Pi via USB. Use python package manager to install one-easy-protocol on your system:

Python 2 -> pip install one-easy-protocol

Python 3 -> pip3 install one-easy-protocol

For C++ version of One Easy Protocol have a look at:

Please use the introduction at the links above to setup your remote control system. Here is an example how Conveyor System could be controled using one-easy-protocol.

//External motor control
robot.extmotor.start();
robot.functions.waitFor(2000);
robot.extmotor.setSpeed(50.0); //0.0-255.0
robot.functions.waitFor(2000);
robot.extmotor.stop();
