how to create 3 link robot using robotic toolbox

I'm trying to create a 3 links revolute robot using robotic toolbox release 8.

I define the links as below:

L1=link([0 1 0 0 0],'standard')
L2=link([0 1 0 0 0],'standard')
L3=link([0 1 0 0 0],'standard')
r=robot({L1 L2 L3})
plot(r,[1 1])

but it returns error"Insufficient columns in q"

how to solve this?

[Puneet Thakral]

Undefined function 'link' for input arguments of type 'double'.

I am getting this error ..Can You tell how can i debug this..??

Instead of robot try this commend

arm=SerialLink([l1,l2,l3]);

In plot u made an mistake try this

q1=[0,0,0];
q2=[0,0,pi/2];
q=(1:1:100);
traj=jtraj(q1,q2,q);
r.plot(traj)

[ANDREWS VIMAL]

sry not arm=Serialink,it is r=SerialLink

Im not able to form transformation matrix with link.A, says, too many i/p arguments

Excuse me I am new to this , but can you tell me on what basis are the values assigned to q1, q2 and q ?

start the toolbox first, use the startup_rvc in command window

Try this:

L1 = link([0 1 0 0],'standard')
L2 = link([0 1 0 0],'standard')
L3 = link([0 1 0 0],'standard')
r = robot({L1,L2,L3})
plot(r,[1,1,1]);

The last matrix [1,1,1] is the default positions of the links.

To play further, try

drivebot(r)

Can I use the robotic tool to create a GUI software and export it as .exe file?

Undefined function 'link' for input arguments of type 'double'.

it is giving this error

The references to link should be references to Link

The functions are from the Peter Corke Robotics toolbox https://petercorke.com/toolboxes/robotics-toolbox/
