Hi, I finaly got by filming my 4 servo biped, then uploading it on my computer, then on youtube . I didn’t play with the servo speed so it doesn’t walk very fast. I had a better program for the turn but I deleted it by accident
This biped was made with the parts from the BRAT kit. Since I sent one servo for repair to hitec I only have 5. As soon as I have all my servo’s I will send you a video of my BRAT gait.
It’s amazing how you can get something like this to walk with just 4 servos. The toddler uses just 2 servos but you have those cheap rods.
I have a question regarding the video. Is it nessasary to move the ankle on the leg that is being lifted? Why not just move the ankle with the load and keep the lifted side ankle near 90 deg.? In the video the foot being lifted does not seem to be doing much.
How about a single servo to move both ankles. A setup might be made using string in a flexable but non compressing tube (like break cables on a bike) to operate both ankles for tilting the bot using one servo.
Hi, well, I dont need to lift up the foot with no load that much, but with out it the bot will stay on both feet (on the one that shouldn’t have the load and just the rim of the foot that should have the load…I dont know if you understand, my explanation is kinda bad…
Sam !
Seriously cool dude !
That sure works better then my early 4 servo beta from Lexan components. And this is so much simpler. Good idea, and now to create a new BRAT Jr. Kit…
Actually, the feet in that robot (which I understand come from the BRAT kit) don’t look quite like those pictured for ARF-01… for example, they have a bend on both sides instead of just one. Not sure that matters, but it seems odd.
