Error in the remote control mode?

Takara Tomy's i-SOBOT is the first humanoid "toy" launched at end of 2007. This forum is dedicated to hacking the i-SOBOT.

Error in the remote control mode?

When I use the left joystick to command the i-sobot to turn left in the remote control mode, I found an error. It doesn't turn left but rather turns right.

I verified this error by putting the unit in voice-control mode and telling it to turn left which it did correctly. This proves that it's not a mechanical error but rather a software bug, either in the transmitter side (controller) or on the receiver side (i-sobot).

Anyone else noticed this bug in their unit? I wonder if Tomy is aware of this bug.

Mine turns in the correct direction. Is your robot facing toward you when you observe this behavior?

Yes, the i-sobot is facing me. I tried to command it to turn right and left when facing me and both commands in rc-mode have yielded the same command, the i-sobot turning right. The LCD on the screen clearly displays that the command being sent is a left turn, even though the unit only can turn right. I tried the vc-mode, and when I told it to turn left, it turned left... Strange...

Sounds like a bug, all right. But I wouldn't rule out the supernatural, either.

yeah, it could be 8)

I'm just waiting for someone to hack the i-sobot, perhaps releasing a dev kit for it so you can mod it and control individual servos. The first thing I want to re-write is the walking gait. It's quite stable right now but the feet doesn't have much clearance.

I'd also like to see a plug n play hack kit, to give programmable control over all the servos, and prerecorded sounds. It would be cool to turn i-SOBOT into a full time dog or other emulations. hehe..

On the isobot here, in RC mode, push the left joystick to the left for a left turn, and i-SOBOT turns right. Push the controller to the right for a right turn, and he turns left.

However, side step left and right is correct. In V-C Mode, turn left and turn right is correct.

The directions of the turns given are from i-SOBOT's point of view.

I'm starting to suspect that it's a software and a hardware issue. The software issue being that there were direction flip flopping perhaps in different firmware revisions, and hardware where the joints needed to be realigned (the 444B command in RC mode).

However, I did find it odd that in voice control mode, it was fine...

Oh well, if only the I-Sobot was hackable, we can rewrite the gait sequences to see it do some neat things, maybe even roller skating like its big cousin Pleo? :P

I was also thinking about programming it to roller skate in the future using the hack kit and also to develop some new dance routines. Plus, by gaining computer control, a significant amount of AI and speech could be introduced through program control inclusive of internet control. The internet control could open up access to huge data bases of knowledge and information. i-SOBOT was standing on a slight incline and actually appeared to be compensating to maintain some small incremental changes to balance, or at least in my mind it was doing a terrific job of standing and moving. You can actually hear the servos compensating when i-SOBOT is standing on surfaces other than level.
