Make: Robotic Arms

N

ow that we know that all the joints

for our three-DOF robotic arm are

working properly, and we have tested some

new inputs to control our arm, it’s time to

determine the equations we will need if

we want to integrate inverse kinematics

into our newest robotic-arm design.

One of the biggest challenges this time around

is that we’re dealing in three dimensions. This

means we can no longer fully graph our system

with just one 2D graph, like we’ve done in the

past. Though creating a 3D graph of a robotic

system is possible, especially with more advanced

programming tools capable of displaying more

complicated graphics, such as Python or Matlab, ...
