Telepresence Robot: Basic Platform (Part 1)
Pretty much following the program. Added the switch and labeled the servos and connectors; using green, yellow, and white data wires for the servos. The Uno smd has a snap on base which makes removing the Uno easier but the nylon standoffs are likely too tall to use with the dtmf shield unless I flip ends of the case.
I used a grated cheese container for the body but the lid was too flexible for the torque from the servo so I cut a thin steel plate in a semicircle which worked just fine. I also tried adding a SPST switch to get away from snapping the lid on but it turned itself off with each flip of the h-bridge.
Single Motor Bot
I have lots of scrap wood so used a piece for the chassis. Added a SPST switch for convenience and, to make repressing parts easier, used a Wagon lever nut rather than soldering the motor/battery connection. The spoked drive wheel comes from Harbor Freight; having an odd number of spokes makes centering the wheel awkward.
Basic Electronics Skills for Robotics
No. This will handle single cell lipo batteries. Charging a large lipo (multi-cell) battery requires a balancing charger to keep the charge rate under control.
