Soft Robotics

Soft robotics is a branch of robotics that makes use of compliant (e.g. soft, stretchy, flexible) rather than rigid materials. These kinds of robots are particularly useful in applications involving people and other fragile objects, and they are of particular interest in medical robotics (including surgery, drug delivery and assistive robotics).

Often soft robots are based on biological organisms (which are themselves compliant), and make use of features such as artificial tendons, muscles and blood vessels.

Making Soft Robots at the CCI

Inflatables

The classic image of the soft robotic 'tentacle' is made from cast stretchy rubber, with a chamber that guides airflow through a shaped internal structure. As air flows through the chamber, the shape causes the robot to bend in different directions.

We have Ecoflex 00-30 and 00-50 Silicon Cure Rubber (00-50 is harder, 00-30 is softer and stretchier). This is a skin-safe silicon rubber that can be cast into 3D-printed moulds. We also have air syringes (for manual testing), and 5V air pumps, tubing and valves.

If you're interested in using the silicon, come and chat to the technicians to borrow it. We have some example moulds and tentacles in the hack space.

Textiles

It's also possible to fabricate robotic limbs using the knitting machine, using threads/wires woven into knitted fabric as tendons. CMU's Morphing Matter lab has a project on creating knitted actuators. We've not done much research into this here but want to develop it further, if you're interested come and chat to us.

Using Dobot Magician V2

Dobot Magician V2

What is it?

The Dobot magician is a 4 Degree of Freedom robotic arm.

What can it do?

Some use cases of the Dobot Magician consist of:

• Drawing of writing using its pen end-effecotr.
• Pick and place using its suction or fingered gripper.
• Basic 3D printing with a 3D printer nozzle end-effector add on and a prusa slicer.
• Laser etching with the laser etching add on.

Dobot magician basic setup

What you will need

The setup

Note: Ensure that there are no obstruction around the robot.

1. Connect the Dobot Magician to your computer with the supplied USB cable.
2. Connect the DObot Magician to a power source with the supplied power adapter.

Powering on/off Dobot Magician

Power on

Before powering on the Dobot Magician, align it into its neutral position as seen in the image below and then press down on the power button that is located on the base of the robot.

Once the robot is powered on, the LED indicator turns yellow, and all stepper motors lock. After about 7 seconds, the robot will play a short "beep" sound and the LED indicator will turn green. Now the Dobot Magician have completed its power on sequence.

Note: If the LED indicator is red after the robot is powered on, this means that the robot arm has reached one or many of its axis limits. To get it back working,just press and hold the unlock button located on the forearm of the robot and move it to a desired position.

Power off

When the LED indicator is green, press down the power button to turn off the robotic arm. In this case, the forearm moves slowly to the rear arm and stops. Then it has completed the power off sequence.

How to control Dobot Magician?

There are two ways of controlling the Dobot magician.

1. Using DobotLab
2. Using python

Note: Any software or documentation for the Dobot magician can be found within the download center of Dobot's website but in order to download anything from there, you will need to create an account with them.

DobotLab

DoboLab is a web based interface that is used to teach, learn and work with the Dobot magician and some other Dobot products.

To use it , you can click here or just search for "DobotLab" on your favorite browser. It should look something like the image below.

You can register with DobotLab if you would like to save any progress but this is completely optional.

On the DobotLab page, choose any of the application tiles to work with. But once you have chosen an application tile, you will get a pop up stating "DobotLink is not started" and you will also have the option to download and install DobotLink.

DobotLink is the piece of software that has the drivers for controlling the Dobot Magician and acts as a bridge between the DobotLab and the Dobot Magician. Make sure you download and install this, as without it you will not be able to control the robot using DobotLab.

If you have previously downloaded DobotLink, click on "Start" if not download and install it and then click "Start".

If everything goes well, the pop will say "DobotLink started successfully" as shown below.

Click "Ok" and it will continue to the chosen application.

On the application page, on the top right of the screen you should see the following.

Here, if you click on "connect", it should connect you to the robot and if you then click on the "arm control panel", a control panel such as the one given below should appear which will allow you to control the Dobot Magician.

Feel free to play around with the other application as well and if you need any more details, have a look at the user manual which can be found within Dobot's download center . The document you will need to search for is Dobot Magician V2 User Guide (DobotLab-based).

Using python to control Dobot Magician

There are two options for controlling the Dobot magician using python.

None of these options have undergone extensive testing, use it at your own risk.

1. dobot-python by Alex Gustafsson (Recommended as it uses the newer communication protocol v1.1.5)- click here

2. pydobot, a python library for Dobot Magician by Luis Mesas - click here

Troubleshooting

1. Serial not found error - You might get the serial not found error, it means that you don't have pyserial installed, to install it use the command pip install pyserial or python3 -m pip install pyserial.

Frequently asked questions

1. The LED on the robot has turned amber instead of green, what should I do?

   If the LED on the robot has turned amber during start up, that means the robot is in a restricted area. You will need to manually move it back to its safe operating space.

   To do this, simply press the circular button which has a logo of an unlocked lock that is located on the forearm of the robot. While holding the button, move the arm of the robot out of the restricted area.

What is it?

UR5e

The UR5e by Universal Robots is a 6 Degree of freedom robotic arm. It is the gold standard for collaborative robots in the industry as it is designed to work alongside humans.

Robotiq 2F-85 adaptive gripper

The 2F-85 adaptive gripper by Robotiq is an end-effector that is commonly used with robotic arms such as the UR5e. But the 2F-85 that we have at the robotics lab is rather special as it comes with a camera module as well.

What can it do?

The UR5e on its own is not of much use as it is a robotics platform and we as the user need to define an application to make it useful.

For example, since we have the 2F-85 gripper attached and setup on the robot arm we can now program it to carry on applications such moving objects around the workspace of the robot or carry out a repetitive process such as pick and place.

If you'd like, you can also design and attach your own end-effector to the robot which could give it a new capability!

The bottom line is, if you need to do something which requires repeatability, precision and accuracy, this robot might be able to to help you out.

Getting started

Core components of the UR5e

1. The robotic arm
2. The control box
3. The teach pendant
4. The gripper

Power on/off

Power on

1. To power on the robot press down on the power button located at the top of the teach pendant. You will notice that the LED within the power button turns green and after a couple of seconds you will see the Universal Robots logo as shown below.

2. The screen will then change to a loading screen as shown below and it will take a couple of minutes to load completely.

3. Once the loading in complete you will see a getting started screen as shown below. At this stage only the control box has booted up but robot arm itself is not powered on.

4. To power on the robot arm, click on the red button that is located at the bottom left corner of the screen.

5. You will get a pop up screen as shown below and within the pop up screen, click on the "ON" button. You will notice that the circles with the status will change to green and the status will change as well.

6. After a couple of seconds, you should see that the "ON" button would have been replaced with the "START" button. Now, click on the "START" button, you will hear some clicking noises coming from the robot arm, which indicates the breaks of the robot arm are being released.

7. If everything goes well, you will see that all the circles will be green and if you look over to the bottom left corner of the teach pendant, the red button we initially clicked is now green and it will also say "Normal" next to it.

8. Now you can exit this screen by clicking on the "EXIT" button located at the bottom left of the screen.

Power off

To power off the robot, press down on the power button that is located at the top of the teach pendant and then select "Power off" on the pop up. If you were working on a program and want to save it click on "save program" otherwise click "Discard".

Controlling the UR5e

There are 2 ways to control the UR5e robotic arm.

1. Using the teach pendant.
2. External control using RTDE, URscript or ROS2.

This page only contains the basics and will not be covering external control.

Moving the UR5e

You can move the robot using different methods but to do that, you must first be in the move menu or setting a way point in a program. To navigate to the move button, click on the button that says "Move" which is located at the top left of the screen. It looks like the image below.

The move menu should look something like the image below.

Once you are in the move menu, make sure to change the option in Feature to "Base" instead of "View", so that your reference point is from the base of the robot arm instead of the virtual camera. To do that click on the drop down that is below feature and select "Base". You should see that the arrow keys on the left have changed in colour.

The move menu is simply for moving the robot around, you will not be able to program a path or set waypoints when you are in this menu.

1. Jogging the robot - To jog the robot, press and hold one of the arrow keys on the left hand side of the screen as shown below.

2. Move each joint - To move each joint of the robot individually press and hold the arrows on the right hand side of the screen as shown above.

3. Freedrive mode

   • To move the robot using Freedrive, with one hand press and hold the black button that is on top of the teach pendant. You will see a pop on the teach pendant that says "Freedrive Active".

• Place your other hand on the flange of the robot. Now drag the robot with your arm to a desired position.

Basic motion programming for UR5e with 2F-85 gripper

The main concepts behind programming the UR5e are move commands and waypoints.

Move command

Move commands define how you would like the robot to move in order to reach a certain waypoint.

There are 3 move commands you can choose from:

1. MoveJ - Stands for Move Joint. This means, given two distant waypoints A & B, the robot will take the fastest and easiest route from A to B and vice versa.
2. MoveL - Stand for Move Linear. This means, given two distant waypoints A & B, the robot will move in a straight line from A to B or vice versa.
3. MoveP - Stands for Move Process. With this move command, the robot will move through multiple waypoints with a constant speed. You can also make circles using this move command.

Waypoints

Waypoints are 3D coordinates within the robot's workspace set by the user.

Creating a simple program

In order to create a program, ensure that you are in the programming menu.

1. To navigate to the programming menu, click on the program button located on the top left of the screen.

Now, your screen should look something like the one below.

2. To add a move command, select "move" which is within the "Basic" dropdown list. You should see that a move command with Waypoint_1has been inserted beneath Robot Program as shown below.

The default move command is MoveJ but if you want to change it, click on the drop down to the left for the screen which says MoveJ and select another move command from the dropdown list.

3. Click on Waypoint_1 and you should see the right side of the screen change to the image below.

4. Click on the "Set Waypoint" button. This will change the screen to a similar screen from the move menu as shown below. But the main difference is that you now have an "OK" and "Cancel" button to set or cancel a waypoint.

5. If you want to set the current location of the robot as a waypoint then click on "OK". If you want to set a new location as a waypoint, then jog, drive or Freedrive the robot to a desired location within the workspace and click "OK". You will see that Waypoint_1 is no longer highlighted in yellow, meaning the waypoint has been set successfully.

6. If you would like to add another waypoint, click on "Waypoint" which is within Basic drop down list. Another waypoint called Waypoint_2 will be added into your move command.

7. To set your newly added waypoint, repeat steps 4 and 5.

Good practices

• Do not nest move commands, i.e. do not create a move command within a move command.
• Name your move commands and waypoints so that you know what is happening when the robot is about to execute it.

Controlling the Robotiq 2F-85 adaptive gripper

To control the robotiq gripper using the teach pendant, click on the "UR+" button located on the top right of the screen as shown below.

This will show a pop up screen as shown below.

Select "Adaptive Gripper" as that is the gripper we have and then click on "Activate". You will see the robotiq gripper will close and open.

Once the gripper is active you will see that the pop up will change and give you some options to control the gripper as shown below.

Now, you can open or close the gripper, control the speed at which it opens or closes and the force / grip strength of the gripper.

Adding gripper command to your program

To program the gripper so that it opens or closes when the robot has reached a point, navigate to the program menu and ensure you have set your waypoints by following the instructions in the previous section.

1. Select "URCaps" drop down which is on the left side of the screen within the program menu. It is also shown in the image below with a green box.

2. Select "Gripper Activate" and make sure this is placed at the beginning of your program.

3. Select the waypoint where you want to add the gripper command.

If you place a gripper command after a waypoint, then it will be executed once the waypoint is reached, if the gripper command is placed before a waypoint, it will be executed before the robot starts moving to the waypoint.

4. To add a gripper command, select "Gripper" from the URCaps dropdown.

5. One the right side of the screen, you should now see some options related to the gripper.

6. Click on "Edit action" and then choose whether you would like to open or close the gripper.

Do not choose a percentage for opening or closing the gripper as this could cause issues. The gripper should either be open (0%) or close (100%).

7. Adjust the speed and force of the gripper according to your need. Click on "Save action" when you are happy with your settings.

8. If all goes well, you should see the gripper command "Gripper Open" or "Gripper Close" based on which action you have chosen.
