Exercises 7.5(c), 7.6, and 8.1 are coding problems. You can work directly in Deepnote, and once you are satisfied with your work, download the final version of the notebook and upload it to Gradescope. (Please use Gradescope to tag the solutions in your pdf file with the corresponding exercise number, it makes grading much easier!)

If you do not have a Gradescope account, you will be required to create one. Please use your @mit.edu email to register. Then look for class 6.8210 Underactuated Robotics, and join using the access code we provided in Piazza.

You will have to make two submissions for this problem set:

• Problem Set 2, Written Submission. A pdf of your answers to the written questions. This can be either LaTeX, Word, or hand written (in the latter case, be sure it is legible!).
• Problem Set 2, Notebook Submission. The final version of your Exercise 7.5 notebook minimum_time.ipynb, the final version of your Exercise 7.6 notebook lp_dp.ipynb, and the final version of your Exercise 8.1 notebook drake_diagrams.ipynb. These can be downloaded from deepnote after you finish to work on them. Please double check that the notebooks you are submitting have exactly this name and extension.

In our testing, Gradescope will give you a grade, and you can resubmit as many times as you like before the deadline.
