Schedule

Week 1: June 18-22 -- Introduction/background
Week 2: June 25-29 -- Building	Monday ROS joystick listener node called "bumbersnoot_boss" created Changed Jetson hostname to bumbersnoot Verified that new, long M2.5 screws fit into XL-320 servo horn Ordered micro-USB hub and correct power+data SATA cable for SSD (arrives Wednesday) Got Dynamixel XL-320 to move! Power switch was in wrong position? Should be to LEFT as you look at switch end of board. Got GUI and position control from here working; velocity control still no go Tuesday Figured out mapping of joystick buttons to their indices into buttons array Made some plans about modes and capabilities of training/testing program (written on whiteboard) Started integrating Dynamixel includes and package depends into listener program. Now callback is executed when dynamixel/XL message arrives. Batteries have their own IDs? single_manager barfs when multiple Dynamixels connected? Found multi_port program that might be the path to dealing with multiple dynamixels at once To do: Get joystick-based Dynamixel control integrated into bumbersnoot_boss Logs with timestamps, directory creation Integrate RealSense capture code into bumbersnoot_boss Get multiple Dynamixels turning with velocity control Add SSD for mass storage Can micro-USB port be used for keyboard/mouse? Or powered USB hub to allow camera along with keyboard/mouse?
Week 3: July 2-6 -- Building	To do: Imitation learning test from tripod-mounted camera Rough chassis assembled Camera on robot Jetson powered by battery
Week 4: July 9-13 -- Building
Week 5: July 16-20 -- Teaching/learning
Week 6: July 23-27-- Teaching/learning
Week 7: July 30-August 3 -- Write-up and presentation prep
