Remote Hexapod Control?

Merry Christmas-Eve-Eve!

A lot of the hexapod projects I see use onboard electronics to control the robots movement using Phoenix Code or some other system. Has anybody tried doing this remotely instead, i.e have a computer calculate the IK and feed commands wirelessly to an SSC-32?

I’ve got this idea for a control system to operate different kinds of multi-legged robots generically by just specifying the number of legs and limbs, but doubt the botboard or arduino would be able to handle it at the speed required. So, are there any disadvantages with sending servo commands wirelessly instead? Can it be done fast enough?

It’s been done. There is a thread here where the PC was drawing a 3D version of the robot and sending data to the real robot in real time. The BAP can send this data at 38.4kb and it works just fine. (It can now do it at 115.2kb) So yup a PC can do it fast enough. The BAP/SSC-32 combo or the ARC-32 may be able to do this. I found out a long time ago, never say never. lol

Thats good news! I was worried that 115.2kbps wouldn’t be enough to transmit commands for 32 servo’s at 50Hz. Or is 50Hz unneccessary for hexapod walking?

Here are some topics for you to study. :wink:
