    Thanks for the video tutorial! It's the kind of video I was looking for! Please upload more content about it and keep up the good work! :)

    I want to give a certain coordinates of a point so that I want the end effector of robotic arm go to the given coordinates. What do you suggest?

    Is it possible to calculate the Inertia Matrix, Friction Effect and Gravity effect of a robot, if you know the DH parameters, using the peter corke toolbox? I have been struggling with this, please let me know if you have a solution. Thanks.

    Is it possible that this syntax does not exist anymore? I get the following error when trying to build one of the links (i.e. L(1)): Check for missing argument or incorrect argument data type in call to function 'Link'.

    Hi, thank you so much for the tutorial. I have one question. Is it possible to add more than one waypoints? So the robotic arm can move in a zig zag motion from top to down for example.

      Hi. Of course you can, I show how to plot a complex trajectory in the tutorial n°4

    @rizamboi2776 3 года назад

    wait, i dont quite following. Isnt this forward kinematic to simulate trajectory then? since i control the robot using it's joint angle rather than the position of xyz or there is a step i skipped over?

    • @amazingengineering3207
      @amazingengineering3207  3 года назад

      You could use the inverse kinematic. So you get the joints values in 2 position and you can make the trajectory

    • @rizamboi2776

      the matrix in q0? which one is the xyz position?

    • @amazingengineering3207
      @amazingengineering3207  3 года назад

      q0 is the joint vector of the initial position

    If I have all the dimensions of my robot, can inverse kinematics of the body be performed with this? For example, if I wish for the body to be in a specific orientation then that will correspond to a specific joint angles. If you think it is possible, what are your suggestions?

    • @amazingengineering3207
      @amazingengineering3207  3 года назад

      You can simply use the ikine command

      @@amazingengineering3207 I realize I was not clear. This would be for a quadruped robot (4 legs). So the SerialLink object will contain 4 legs (1x4). I have not been able to figure out how to apply inverse kinematics to this whole robot.

    • @amazingengineering3207
      @amazingengineering3207  3 года назад

      You could analyze every single leg considering the foot as the end effector

    • @amazingengineering3207
      @amazingengineering3207  3 года назад

      You can watch tge 1st video tutorial of my MatLab playlist where i show a SCARA robot. Anyway, if you want to use a prismatic joint, you can write link command in this way: L = Link(theta,d,a,alpha,1). If you write 0 or only the DH parameters you will have a rotary joint
