How to design Robots using MATLAB 2021 | SimScape Toolbox | Robotics System Toolbox

This video will introduce the basics of how to design and drive a simple robot using MATLAB's Robotics System Toolbox and SimScape Toolbox. Though the video uses a very simple example (First two joints of a SCARA robot), but aims to establish a base using which more complex robotic systems may be implemented and simulated.

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.

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

[@LearningOrbis]

30 degrees with respect to the world frame's x-axis? You have to do that programmatically, there is not such option in the joint.

[@LoveLilyS]

Use this method,if i want to use dynamic model,such as inertia matrix/gravity/centrifugal included in SimScape Toolbox?

[@LearningOrbis]

Yes, definitely. This method utilizes physical system modeling and therefore inertias, and forces are considered.

[@amr.a-m8350]

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 ?

[@LearningOrbis]

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.

There shouldn't be any problem in importing cartesian joint. Can you explain what error you are getting?

[@souravhawaladar3870]

Suppose the second link we hand to incline it on base at certain degree. Which block should we use to define the angle?

[@LearningOrbis]

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.

[@user-km1le1rv1k]

I use Variable Brick Solid for the link, and it seems cannot use 'importrobot' to load the rigidBody Tree. Do you have any solutions?

[@LearningOrbis]

Variable brick solid is not a rigid type link, therefore it cannot be used with Robotics System Toolbox. Use a simple solid.

[@bilalzirar5045]

Good luck 👍 💓

[@LearningOrbis]

Thanks ✌

[@kanishkakeshara1629]

Sir when it comes to UR5 robot simulate like this should we consider real height of base and links??

[@LearningOrbis]

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.

[@souravhawaladar3870]

Is there similar video for 6 axis Robotic arm?

[@LearningOrbis]

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 kzbin.info/www/bejne/qaSrdXmVaceUgJI where I have loaded a 7 DOF robot into MATLAB and solved its Forward Kinematics.

[@trunghieutrinh778]

Sir, i have and error while try to choose Source Body and Target body, it said Error evaluating MaskParameterCallback of Get Transform block...

[@LearningOrbis]

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.

[@iqhmannabil7455]

Can you do control using PID?

[@LearningOrbis]

[@LearningOrbis]

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.

Thank you 😊

[@anthinikou3114]

Sorry but on 14:28 i cannot see the left information on mine? What am i doing wrong?

[@LearningOrbis]

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.

[@adhraahussam2335]

Hello sir , thank you for your. How I can get mathematical model for this robot?

[@LearningOrbis]

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.

Sir please suggest books to learn simulink , control

Any standard control book will do the job, but you should look for tutorials and online resources for simulink.

[@rajeshbabu5971]

sir.., can you explain (25-26 ) minutes briefly. I mean, after completing the robot design before implementing the trajectory plan.

[@LearningOrbis]

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.

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.

[@LearningOrbis]

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.
