Servos Suited For Legs
Can anyone provide some advice on high torque servos suitable to use for robot legs? I just finished installing the standard EZ robot HDD servos - one in each hip and one in each knee. When powering up, the robot will topple over as these servos are not strong enough to hold it up (the start up position is 90 degrees). My robot is 4' high and the top half weighs a lot more than its legs. I want the robot to slide walk, not lifting the leg at all. CR servos will be in the feet.
Any advice would be appreciated.

Sorry @DJ. I thought the challenge was open to anyone. However it sounds like you won anyway. I didn't remember the one from Spaceballs till you mentioned it. Congrads! LOL.
What was Perry thinking of with a tv show wearing spandex?
Buck Rogers was a TV series and not a movie. I used to watch it every Sunday Night. I particularly liked Dr. Theopolis who was like a council member robot that this robot (Twiki) wore around his neck.
As far as the spandex comment, they had some pretty awesome costumes in the show. At least awesome to the 13 year old boy I was at the time. The show was kinda known for it.
And don't forget the very evil Princess Ardala
I had no clue buck Rogers was also a tv series. I watched the movie a couple times - but had no idea it was a series. Guess I know what I’ll be watching this winter
I own a robot that walks :-)Thanks for all the comments and links. I will follow up the link to ServoCity. The servos in the legs can be swapped with other servos easily enough, although they are strong enough to move the legs if the robot was placed on a harness. The arms I have tested with the EZ robot servos and they work well enough. Twiki's parts were bought from Resident Dreamer, but I am only using the body. I made all the other components as they needed to be light and articulated.
