I have been googling for a source for parts to motorize a golf bag cart. So
that I could press a micro switch on the handle and have a small DC motor
turn the wheels of the cart at about 4 mph.
Has anyone done a similar project or know of a god source for information
and parts ?

I don't know about the propulsion feature, but I think that as long as
you're going to pimp out the thing, you should watch the movie Caddy Shack
again, and pick up some hot ideas from Rodney Dangerfield's rig.
The battery is going to be a killer. You might pull it off, but think about
the battery first.
Calculate ampere-hours based on the current drain on the battery and the
on-time for 18 holes. Then, find affordable batteries in that range using a
2X factor (designs often double the need for reliability). Then, look at
the size and weight of those batteries. By now, you will be somewhat
If you are still avid, think about recharging, life-time, convenience,
safety, corrosion issues, liability, and the list goes on.
maybe you're not a golfer. these gadgets are not uncommon. i've seen
them rolling around golf courses for decades. i doubt all these
manufacturers (and there are many) would be in business if their
products weren't reliable as advetised. google "electric golf caddy".
No idea what Mr. Schuler's problem might be, but this isn't a terribly
Head off to Ebay & get a scooter motor -- maybe $30 - $50
Next, you'll need batteries. These are heavy but not unbearable. 12v
golf cart batteries work fine, but you can also find scooter batteries.
These will setup you back another hundred or so.
Finally, some kind of motor controller. Again, it looks like you can ge
this on Ebay for around $20.00
Now you just need to put it all together. I'd start with a basic bag
cart from the flea market or a garage sale, then figure the placement
for the motor & batteries and finally a way to attach the motor to a
wheel. The batteries are going to come in around 25 - 50 lbs, so you
might want them to be easily removable for transport.
You might want to ask over in comp.robotics.misc as it's full of useful
A few years ago I saw a few autonomous carriers -- they'd literally
follow you around the course. I wonder whatever happened to them.
Well, this one's not autonomous, but it does have a remote you can hide
in your pocket and fool other golfers into thinking it is.
But, this company promises that they'll have their "follow me anywhere"
model available through a dealer network soon:
And Segway is getting into the act too:
Another couple of options occured to me:
The drivable electric cars that are popular with the kids at the moment.
You can get these new close-out for $100, or scout the garage sales &
get one for less than $50. Everything you need -- motor, wheels, batteries.
I've also seen drivable carts online new for $200. Again, everything you
need, just reconfigure.
Unfortunately, one of the most expensive bits is the batteries and
there's not a lot you can do to get these on the cheap.
Best o' luck
