B.O.B. Bret's Omnibot

cool Wow @bret.tallent B.O.B. is looking sooooo good! I'm really impressed with the arm movement on your bot. Those are high-power servos, right?

I think you mentioned in another thread that you were thinking of stopping work on B.O.B. I really hope you decide to finish him. It's really a great looking and working bot!

Thanks Everyone! Work on Bob will continue...I just see so many projects I really want to do. All in good time I guess. I'm just frustrated with the servos not working correctly on the wrist and claw. I am going to tie them into the separate power supply like the HD servos and see what happens. Any suggestions would be welcome.

Have you tried different servos on those same ports ? And what about the kg/cm rating ? maybe a higher rated one would work. And thanks for posting the video ! I've just pulled apart my Buster and working on a plan . J.W.

Okay, I tried a multitude of things and finally fixed the movement (see new video). I had to adjust the claw mechanism itself as it was binding up, and completely replace the wrist servo as it was just funky. Now he is right as rain.

YEA !

@bret.tallent

Very Coooooolllllllllll

Did you change the type of servo in his wrist? or was it just a faulty one originally? You get some duds with those 9gm servos sometimes. I think I will go with mini 2.5kg digital mg's same as the ones I use in my 450 heli.

@RichiesRC - Thanks! servo is same type, the original was faulty. As cheap as they are not a big problem to replace. Next up is the ping sensor, head, and camera. Then on to the drive section. I think I am going to use jstarne1's suggestion of the dynamat.

I picked up some of those for cheap servos too. I think $1.99 each J.W.
