Larry V4.0





So, the point of Larry 4.0 was to work with turning power from the motor 90 degrees.  That was accomplished; although, it's a little clunky.  Gravity is what holds the gears together and the delicate balance is upset by the tension of the sensor cable.  Wrapping it around a post helped.  Also, the torque on the motor is offset by a single pin that prevents lateral movement.  Unfortunately, given the pin points available, this is the only option in this configuration.

In version 4.0, I moved the motors to a vertical configuration.  This was to accommodate a smaller base as the wider base was bending in the middle, giving Larry a very broken appearance.  To make the configuration work, I had to turn the motors around and negate the power values in the programming to make Larry move in the right direction - forward is back and back is forward.

There's only one other thing (right now) that I'd like to work on with Larry.  In V5.0, I would like to move the little motor inboard and vertical.  This will allow me to rotate the IR sensor 360 degrees.  I will re-program Larry to look for a better path, not one that is just 35 degrees off center and go there.  I am also considering playing with the gyroscope and moving Larry to 2 wheels only.

More to come.
