Daniel - Driving

Tested out driving with new nut

wheels still not well aligned
front wheels are loose
the drive sequence for turning (1 wheel forward, other wheel back or null) doesnt work
the wheels loose on the motor, even with the 3d nut
we need to add the screw with the 3D nut
modified the driving code

Han - 3D Nut Print

Printed nut adapter for rear wheel-motor

Daniel - PRD Updated Parts List

Sailesh - Wifi Sending images

Working on sending an image through wifi

Problem: wifi can only send/receive up to a certain size and the smallest images we can work with are just a few bytes too big

Solutions:

finding C++ alternative
remove some pixels from our image (bottom row)
study the code more

Han, Daniel - 3D print prototype

The toothed model could not go through grass so we are trying this alternative

Was unable to move through grass so we are reconsidering our design

instead of 'cutting' through the grass, we need to have more of an aerodynamic 'scoop'

round the scooping edge and round the corners

Daniel - Frame Movement

With our new nuts, we were able to turn better as the motor wheels could spin more sturdily, but we need to reconsider our front axle design. Currently it is one rod, which means the front two wheels spin together. however we want it so that. while turning, the front two wheels spin in opposite directions.
