 ## Activities
  * Control the arm interactively.

 ```
 > ./armCtl.py
 command# go jib 90
 command# wait
 command# go home
 ```
+
  * Script a simple sequence of moves.
- ```bash
- # my_script.txt
- go jib 90
- wait
- go home
 
- > ./armCtl.py my_script.txt
- ```
+```bash
+# my_script.txt
+go jib 90
+wait
+go home
