  • Would like to see a kit made that is bigger than the Actobitty but smaller than this one. The cost could be half way in-between. My Actobitty goes kind of slow (powering off 7.4 V LiPo) and I don’t like the front caster. Also, the Arduino plastic bracket doesn’t have enough friction so the Arduino tends to slide in it easily I bought the Actobitty before Sparkfun offered them. I think the non-Sparkfun place included a 60 rpm motor instead of the 90 rpm motor. Also they didn’t include the hex wrenches. The service department at SerCy ignored me. Don’t think that would have been an issue if I got it from Sparkfun. This one is cool but a little expensive for me. Maybe the same size as the Magician chassis (or even a little bigger) but with better components (motors). The negative comments on the Magician especially about the motors prevent me from going there. I guess nothing is stopping me from designing my own chassis. One thing I see on the Actobotics parts is that there isn’t any flat plate offered than can span across the chassis. Are we just supposed to make one with ABS or aluminum sheet?

  • How do you mount these speakers to anything, since they don’t have holes?

  • Question about assembling this claw to the pan/tilt bracket. The directions aren’t clear. Should I have attached the pan/tilt bracket to the claw before I assembled the claw? It looks from the drawing that the screw and nut on the base of the claw bracket have to be removed and replaced with the M8x12 screw so that it can screw into the collar parts. Is that right? Right now, with the claw assembled, there is no clearance on the side where the clutch is to take the screw on the base of the claw bracket out and replace it with the other one. What is the role of the stand-off nuts on the base of the claw? I assume it’s an additional attachment point if I didn’t want to use the pan/tilt bracket. Is that right? Sorry if these questions are obvious.

  • The bracket comes with the servo to move up and down. I think I’d call that “tilt.” For the claw, you bought a servo to open and close it. But if you also want to move from side to side (i.e., to pan), then you’d install another servo in the rectangular hole on the bottom of the pan/tilt bracket. How to do it is not shown anywhere here but I suppose you’d attach the horn to something immovable and then the servo and bracket would move together. I wonder how much force that medium servo for panning can take with the tilt bracket and claw hanging off of it? Even though the brackets themselves are metal, a lot of the mounting hardware is plastic.

  • is the motor output voltage regulated or is it the same voltage as the motor supply voltage? The rated 7.2 V motor has a range of 5 to 7.5 V, according to the specs. So if I use 2S LiPoly, do I need to put in a voltage regulator that keeps the voltage within the spec.

No public wish lists :(
