Second mechanism added 180 degrees out of phase to produce one drive pod.

By placing the rocker on the opposite side of the crankshft, one crankshaft operates both mechanisms.
Only need a 1 cylinder type crankshaft rather than a 2 cylinder type crankshaft is needed so it's a bit less wobbly

Some hex nuts replaced with nylocs. Either the hex nuts tightened and caused binding issues or loosened and the screw heads clashed between the two mechanisms.

Drive pod now runs a little free-er under manual test.

Brushed motors ( 12V 1000 rpm) on order. If the mechanism doesn't work, I can use the motors in a more conventional bot.
