how to create 3 link robot using robotic toolbox

249 views (last 30 days)
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?

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

The references to link should be references to Link
The functions are from the Peter Corke Robotics toolbox
