| Hi, I what to built a four wheeled robot which uses differential steering. Have somebody an idea to transfer the motion energy from the motor powered back wheels to the front wheels? Jens (25 years ago, 22-Sep-99, to lugnet.robotics.handyboard)

| before I reinvent the wheelI haven't actually done this, but I'm pretty sure the theory is ok... On the handyboard web page is the pa79600 icb file which lets you use port a bit 7 as serial i/o. I have successfully used this to control some (...) (25 years ago, 22-Sep-99, to lugnet.robotics.handyboard)

|
| Hello 'Botter, I think I am about to ask a stupid question but as a precaution, will the Expansion board be "ok" with a new 12V motor supply rather than the 9.6V connected to the Power Expansion header (J13)on the HB since the Expansion board and HB (...)

| | | | | OVER 1 AMP
|
| Oh yeah, one more thing, how about connecting a 5 ohm resistor in series with a DC motor and there are 2 amps flowing, then the resistor is dissipating 20 watts of heat. Now I could have a higher value for the resistor, like 7, 10 ohms, I think that (...) (25 years ago, 21-Sep-99, to lugnet.robotics.handyboard)
