The new HSR-8498HB from Hitec was custom designed
for the popular ROBONOVA-1 robot and is a great choice to use in your next
custom robot project. The HSR-8498HB servo uses super strong Karbonite
gears that will never wear out or create sloppy gear lash. Another
unique feature of the HSR-8498HB servo is that it can be built in three
different configurations using the custom accessories included in each
package. Build it as a standard servo design, or use the custom “idler”
wheels to create solid and sturdy robot joints.
