Figure 1-4 SumoBot Servo Connections
The instructions that make the SumoBot move forward starts with these
The SumoBot's left servo is connected to P13, so I/O pin P13 is given the name
ServoLeft
In order for the program to apply 100 pulses, a
This
to Robotics with the Boe-Bot, this loop delivers 40.65 pulses per second, so the SumoBot
will roll forward for 100 ÷ 40.65 = 2.46 seconds.
Your Turn - Does Angle of Approach Matter?
By experimenting with different angles of approach, you might (or might not) find an
even more "winning combination".
approaches. The edge of a SumoBot's plow collides with the flat of the other's (left). The
SumoBot is using a curved approach (right). They aren't necessarily better approaches,
but they are worth investigating for the sake of better understanding the relative merits
and drawbacks of each.
