the parts list for the puppet is a joke everything is overkill for no reason you could easily do it for 200 same size and function

- TaylorAlexander 6y agoI've built several servo powered walking robots. Torque is a major concern, and obviously weight plays a part in how much torque is required. The recommended servos look to be $30 each, x12 means $360. If you spent $200 just on servos you'd have to settle for $16 servos. Probably less torque. That would mean that at full leg extension the robot might not be able to support itself. That would be an annoyance when trying to focus on walking algorithm development, which is usually the fun part for these small walkers. You can definitely do something for cheaper, but I wouldn't call this a joke. When I was 15 (20 years ago lol) I designed an 18 servo hexapod. I saved up $350 from cleaning horse stalls and my dad agreed to pay the other half, and I spent $700 on servos. It was great to learn about inverse kinematics before ever setting foot on a college campus!
- jsjohnst 6y ago> You can definitely do something for cheaper If the 35kg is in fact needed (which I’m not prepared to debate, probably needed, but I can’t prove / disprove), you are exactly right. Yes, you could maybe save a couple dollars with cheaper servo brands, but honestly for a 35kg servo, you’re going to pay a decent amount for 12 of them.
- TaylorAlexander 6y agoYes and I noticed this robot can jump completely off the ground. Pretty nice!
- detaro 6y agoNow we're curious about what part replacements you'd suggest.
- taneq 6y agoWell don't be shy, post some videos of your $200 quadruped showing off its flexible dynamic gait performance.
