(...) The best solution here is to replace the HB's 9.6v batt with a 6v one. Once you get past the L293's, you'll be giving around 4v to the motors, which should be fine. -F (29 years ago, 5-Feb-96, to lugnet.robotics.handyboard)

| | Enable interrupts within IC?
|
|
Hi all, I'm trying to use IC to poke in an interrupt routine (the IC3 interrupt from pin PA0) assembled using PCBUG11 at $B600. I can set all the register bits correctly, but I can't execute the CLI (general interrupt enable) HC11 opcode from within (...) (29 years ago, 6-Feb-96, to lugnet.robotics.handyboard)

why not use the cars drive electronics, just bypass the radio part, it would take a little work to find the points where the motors are turned on, but it should work. Just watch out for other people with remote control units. (...) (29 years ago, 6-Feb-96, to lugnet.robotics.handyboard)

| | Using cheap RC chasis as 'bot
|
|
Hello All, Concerning the thread of RC chasis with the handyboard, I've done that (albeit with the 6.270 board) and found that it was not that tough. I was fortunate to find a decent RC van setup for only $20. It was some time past Xmas of last year (...) (29 years ago, 6-Feb-96, to lugnet.robotics.handyboard)

like Ram, I connected successfully a radio shack RC truck (4WS) to the handy board. for the DC motor controlling forward and backward speed, I found the 2 entries of the h bridge connecting the motor. I replaced the cheap front end steering servo (...) (29 years ago, 6-Feb-96, to lugnet.robotics.handyboard)

OK, time for me to chime in on this thread... The biggest problem, IMHO, with using a cheap RC car/van/truck as a 'bot base is that they all use Ackerman steering (two non-steerable driven wheels in the back, two linked, steerable, non-driven wheels (...)

(...) The biggest problem with tank like drives is the marks/scratches on the floor. Any robot with any weight will probably damage a maple or other hardwood floor in short order. They work fin in a lab with waxed tile floors that no one cares (...) (29 years ago, 6-Feb-96, to lugnet.robotics.handyboard)

I've always known that my mechanical skills were nowhere near as good as my electronic/programming skills, and getting a suitable base set up is a formidable problem for me. Something like what you propose would be the (...) (29 years ago, 6-Feb-96, to lugnet.robotics.handyboard)

Then glue a hall effect sensor to the axle. When the wheel spins, the (...) (29 years ago, 6-Feb-96, to lugnet.robotics.handyboard)
