Hi all, Ive been having problems with my bots supply for a while now. The problem is that the motors (LEGO 9v ) seem to be drawing too much current. whenever my bot changes direction or trys to accellerate from a standstill, the board resets. Im (...)

Its sound like your motor is drawing excessive current, thus resetting your Handy Board. You might want to beef up to a higher capacity battery or you can try running your servos off an external power source. Good Luck. (25 years ago, 7-Feb-00, to lugnet.robotics.handyboard)

I am trying to interface an HP quadrature-type encoder to the handyboard using the HP HCTL-2016 encoder chip. The problem is that the chip requires a clock signal to synchronize the data latching and transfer functions and I am not sure which type (...) (25 years ago, 7-Feb-00, to lugnet.robotics.handyboard)

Thanks for the tip! I am new to this, and I am really anxious to build robot with legs.

It sounds like you might have a mechanical, rather than electrical, problem. Servos typically have some sort of stop nub on the gears so that they can't rotate past a certain point. If you don't cut off the nub with a hobby knife or saw, the motor (...) (25 years ago, 5-Feb-00, to lugnet.robotics.handyboard)

(...) Knudsen in his book (p 223) uses Digi-Key part number DN6847SE-ND, which, he says, is "sticky" in the sense that it remains set until explicitly reset. I have no experience with it. (25 years ago, 4-Feb-00, to lugnet.robotics.handyboard)

Have a look a (URL) is my hobby robotics site. Currently I have a Hexwalker running with a HB. The 12 servo's are simply controller by a PIC 16F84. This PIC is controlled by the HB through an async interface. This makes it lightweight on the HB, so (...) (25 years ago, 4-Feb-00, to lugnet.robotics.handyboard)
