The Gadgeteer has posted a new review of the
Acroname Palm Pilot Robot Kit (PPRK). The Acroname kit is based on the CMU PPRK which has
been covered a couple of times in the past. And, if the cost of the PPRK
is too much for you, have a look at Justin Osborn's less
expensive Palm-based alternative to the PPRK: Palm Bot.
Sorry about the webpage, it's got the original project up there and
hints about the new pneumatics project, but it hasn't been updated in a
while.
I ended up building a pneumatic gripper out of FischerTechnik just right
for picking up soda cans and got some relays for the solenoid valves so
that the SV203 could control them. I also got a small servo and mounted
the IR ranger on it so I can get a sort of arc of distance values. My
"plan" is to program the thing so that it can take the sweep
of distance values and figure out where a soda can is and then go pick it
up. I was going to do that this summer...but summer's now over and it
doesn't look like I'm going to have more free time. One day I'll get
back to working on it again...
