Using force sensors it’s possible to chain a series of servo motors together so they not only move as one, but can detect and simulate the force that another feels. Which means if you built up a tele-presence robot with a servo-driven robotic arm, using the local control arm you could feel exactly what it feels like on the other side!
[Wolf Tronix] saw our post last week on Series Elastic Actuators, and shared what he was working on in the comments. As one tipster pointed out — it deserves its own feature!
He’s been designing his own Real Time Motion Control System and Mini Servo board, or RTMCS2 for short and shown off a short video of it in action. By adding a force feedback sensor to each servo, not only do they copy each other, but if you put a load on one, you’ll feel it on the others!

Recently, a Japanese coder on the DCEmu Forums released Windows drivers for DualShock 3 controllers. While the drivers only support using the controllers over USB and not bluetooth, they do include force feedback and Sixaxis support. Included with the drivers is a configuration tool, and though it appears to be in Japanese there is some explanation of how to use it included in the forum post. We have not tested these personally, but you can try out the drivers for yourself by downloading them from the forum here.

[thomph-zhu] sent in this interesting project. If you’ve ever wished for cat like senses, you’ll dig this. It’s a set of electronic whiskers – it uses IR to detect nearby objects, and vibrates against your head upon detection. It’s definitely an interesting use of tactile feedback. The initial idea is for construction safety, but this could be useful for plenty of other applications. (Robotic control, etc)
[F00 f00] sent in his latest PSP mod. By combining a voltage amplifier, a PIC controller and a cell phone motor he ended up with force feedback enabled PSP. He’s got the PIC set to enable the motor when it detects certain sound frequencies from the speaker via the amp.
The video is after the break.
