 The past several assignments have culminated in generation of a joint trajectory that moves a foot frame of your biped (relative to the torso frame) from one arbitrary pose in planar space, to another. You utilized resolved-rate inverse kinematics to generate the joint trajectory that accomplished this.

 In the Optragen repository, the following demo script serves as a good contextual example to work off of and/or modify to meet your needs: Optragen/examples/pathPlanning/planar2R.m
-In the above demo script, please make sure to change 'SNOPTPATH' to be the location of the 'snopt/' directory you downloaded from Dropbox. Successfully running this script will additionally serve as validation that Optragen and SNOPT are correctly configured on your machine.

 At a minimum, you'll need to define a constraint for your starting condition and one for your ending condition. You'll also need to specify a cost function; you can define your cost function to be energy-like, similar to how the demo script already defines it.

 In preparation for following weeks, please formulate the constraint that restricts the projection of the CoM (of the entire robot) to fall within a connected region on the ground (ie. your 1-D support polygon). You should express the constraint assuming:
-**a.** **LEFT_FOOT** is your stance foot
+**a.** **LEFT_FOOT** is your stance frame
 and
-**b.** **RIGHT_FOOT** is your stance foot.
+**b.** **RIGHT_FOOT** is your stance frame.
-No coding needed - just provide the mathematical expression for each case. You may formulate it with respect to $g$'s (ie. $SE(2)$ elements); if you do, please take time to clearly define your $g$'s.
