I have no idea about Nucleo 767, but I suppose it is some microcontroller. If that's so, and if Nucleo 767 has compatibility with MATLAB, then you may attach a potentiometer with analog input pin of Nucleo 767 and read it in MATLAB. Convert the reading to degrees or radians and provide it to the joint of the robot.
I am making an x-axis travel stage, but I am trying to simplify it do just a plate on top of a rectangular prism. How could I use a Prismatic Joint in the X-Axis direction or use a Rectangular Joint that limits the movement to only the X-Axis Direction. If you have a video on rectangular Joints that would be helpful as well.
RST needs the robot defined in a RigidBodyTree format. You can define the robot through code in a RigidBodyTree format or you can design a CAD model and ask RST to extract the RigidBodyTree from the CAD model. The later method is great for creating a robot as well as its CAD model. That is why I used SimScape to design the CAD model of the robot and extracted RigidBodyTree from it using importrobot function of the RST.
Lower Limb exoskeleton will be like a 7DOF non-planar robot. Kindly watch my video on how to develop an articulated (RRR) robot. I hope that video will help you a lot.
Developing a 6 axis robot is quite lengthy process, instead there are several built-in robots that can be loaded into Simulink and used. You can see ua-cam.com/video/ssHDF_4baJ0/v-deo.html where I have loaded a 7 DOF robot into MATLAB and solved its Forward Kinematics.
Hello in the solver configuration part I have an error about: An error occurred while running the simulation and the simulation was terminated Caused by: ['Robot_Arm/Subsystem/Base /Base ', 'Robot_Arm/Subsystem/Subsystem/Solver Configuration']: 'Robot_Arm/Subsystem/Base /Base ' has zero mass but nonzero center of mass, which is invalid. How can I fix that may you help?
I am making an arm where the base is a rectangle and then the following link which is also a rectangle is falling through the base towards the bottom where it disappears from the page. It's as if the base has a hole and so link 1 falls through it. I don't know why it does this? Thank you
@@LearningOrbis Also, the cad drawing seen in this video - can this be exported? If so, can it be exported as STL files? I'm trying to see if it can be opened in other applications related to Matlab
Though there are ways to generate STL file from MATLAB but i'm afraid none of them converts SimScape model into an STL file. You can consult following to see if they are any useful for your case. www.mathworks.com/matlabcentral/fileexchange/20922-stlwrite-write-ascii-or-binary-stl-files www.mathworks.com/matlabcentral/fileexchange/68794-make-stl-of-3d-array-optimal-for-3d-printing
You are entering some parameter in the Get Transform Block which has not been defined in the workspace. For example, Rigidbodytree of the robot has not been defined or you are using wrong name.
If you are seeing the CAD model in Mechanics Explorer then most probably the left-side tree has been minimized or its window has been shrinked so that you cannot see it. If you cannot see the CAD model entirely then email me your simulink file and then I can guide you in a better way.
For using functions from Robotics System Toolbox we need RigidBodyTree of our robot. You can make this RigidBodyTree through programming or you can make a CAD model of your robot using SimScape and then use 'importrobot' function which will extract RigidbodyTree from the CAD model for you. I have done the later, that is made a CAD model robot using SimScape and then used 'importrobot' function to extract the RigidBodyTree.

Is there a way to put an upper and lower limit on the movement of a rotoidal joint NOT from the previous link but from world reference? I need to put a limit of 30 degrees from X axis on the joint before the end effector
Hello Sir, Thank you for all the videos, it's very useful :) However i am working on 6 Axis robot (PPPRRR), and Cartesian joint cannot be imported to rigidBodyTree, please could you help me ? Thank you so much
To get all the possible XYZ points is a difficult task. Instead, you can use Forward Kinematics Block to get the XYZ positions of the end-effector as it is moving on a given trajectory.

Sir is there any powwsible way to make a workspace for the movement of this end effector, like for this its is a semicircular arc. Can we get a workspace of the different DOF robots. Kindly guide me through this.
That will be a difficult task to do. In fact it won't be difficult it will be too lengthy... You may actuate all joints either turn by turn or in combination and keep track of the end-effector. It's better to use SolidWorks for that. You can create the CAD model of the robot in SolidWorks and move its end-effector by dragging the end-effector to different locations to see where the end-effector can reach.
@@LearningOrbisbut sir in solidworks also it is not possible to draw workspace. And I want to control the joints after one another, like in a sequence, jow can I do that

Use this method,if i want to use dynamic model,such as inertia matrix/gravity/centrifugal included in SimScape Toolbox?
Yes, definitely. This method utilizes physical system modeling and therefore inertias, and forces are considered.
Awesome! ❤

I need to no when you created rigid body tree as DOF2_ARM why do you choose a Sims cape from file DOF2_Test1 to work in RST ?
RST needs the robot defined in a RigidBodyTree format. You can define the robot through code in a RigidBodyTree format or you can design a CAD model and ask RST to extract the RigidBodyTree from the CAD model. The later method is great for creating a robot as well as its CAD model.

Suppose the second link we hand to incline it on base at certain degree. Which block should we use to define the angle?
Rigid Transform Block will in this case have the rotation portion as well that will make the next link incline with respect to the previous.
Great Explain.
Glad it was helpful!
Sir when it comes to UR5 robot simulate like this should we consider real height of base and links??
If you don't then position of the end effector will be with respect to the base frame normally attached at the center middle of the base.

I use Variable Brick Solid for the link, and it seems cannot use 'importrobot' to load the rigidBody Tree. Do you have any solutions?
Variable brick solid is not a rigid type link, therefore it cannot be used with Robotics System Toolbox. Use a simple solid.

MATLAB doesn't help with that. You have to generate its dynamic model in mathematical form on your own or from the blocks of the Simulink.
