My little walking robot, that this blog was originally created to describe, gradually beat itself to death through performing at conventions and Makerfaires over a period of several years. Broken servos were easy (if expensive) to replace, but eventually welds cracked in the legs and the servo control board developed intermittent faults. Fixes to the structural problems just made it heavier and pushed the already overloaded servos further. About a year ago I gave up and declared it dead.| Drew's Robots
Several years ago when looking for cheap servos to use for my walking robot I purchased a handful of HXT900 micro servos from HobbyKing. They seemed like an incredible deal for less than $3 each, but after brief experimenting I gave up on them. They were very jittery, not terribly strong, and when run at 6V the motor would burn out quickly if the output was stalled. I tossed them in the junk box and forgot about them, writing them off as not usable for my robots.| Drew's Robots
