Hi everyone,
I’m a 56 y/o male from Germany, Electronics Engineer specialized in Lithium battery and electric propulsion in general. I’ve been a pioneer in DIY multicopters and 3D-printers as a hobby.
I joined the forum today, because I started robotics lately ( I know, I’m late to the party…)
I’ve ordered a phoenix-like hexapod and ps2-controller (both clones), because I have designed a servo-driven mechanism that is able to really jump/kick/box or throw a ball. I’d like to integrate my design into the hexapod, but for now I’m struggling with creating ‘action groups’ for my Lobot servo controller that came with the ps2-controller.
I don’t want to use other peoples inverse kinematic equations, so I started to build a ‘teach-mode’-servo-arm. I can move it by hand and the same arm on the opposite side of the hexapod mirrors the move. ( still developing the SW for it)
I’m not familiar with the current market, so here’s the first question: Is there a teach-mode servo on the market? Does Lynxmotion’s servo controllers or smart servos offer a way to teach moves other than moving sliders on the PC-console?
Second question: Is there a servo-driven robot out there, who can really jump or kick or throw a ball ( biped)? I’ve only seen a few pretty lame videos so far…

The hardware allows it, and it is in the works to create a sequencer with teach mode, but has not yet been started as a general sequencer. It is in place for the Lynxmotion SES V2 arms (where you physically move the arm and “teach” it the sequence.

A hobby servo which can provide very high speed (enough to throw an object) as well as high torque (to support the weight of an object) is not easy to create. You’d need to think about using high torque BLDC motors with or without a low gear ratio.

Thanks for the welcoming words,
The video is not what I had in mind. My ‘potmeters’ have the same housing dimensions as a standardservo. I can replace the servos of one leg and thereby have the same kinematics/angles. The software runs on a ESP32 and sends data to a PC-terminal. Then I can copy&paste them into the servo sequencer and create my action groups.

I’ve already solved this problem in a ‘proof of concept’ build. It can throw tennis balls and heavier stuff 50-100cm wide. More than enough power for soccer-bots and such.
COVID blocks further action, but in a while I’ll be able to show a more decent build, I hope.
Smart servos have the position feedback you need, as well as the torque, but not the “throwing speed”. Looking forward to seeing your proof od concept.
I’ve made a video of it, but that reveals too many secrets
If I gain enough interest between the forum members, I’d like to ask robotshops ‘accelerator’ program for commercializing the idea.
