Read
it Now!
by Lonne Mays
Is
your favorite robot getting to be a bit too
atrophied for your taste? Does it lack vim
and vigor? If so, don’t worry. What you need
is high torque and speed. With the MC33887D
integrated H-Bridge and a little direction
from Lonne, you can bulk up your robot in
no time. p.30
Keywords:
Robotics,
torque, MC33887D, H-bridge, speed, servo amp,
MC33030, MC74VHC1G66, analog switch, test-pulse
