Hello again fellow forumers, I have arrived in Toronto safely and things are slowly getting in place here. I have new ideas for a robot that I want to build and I'm looking around to see what's the best way to make the parts I need.
I want to build a robot from acrylic plexiglas (clear, to see the mechanisms inside, even clear servos will be used). The robot will use Admin's Axon, 2 DC motors with encoders, treads (from Vex or something similar), a bunch of servos (about 20 or so), an AVR camera (hope to be able to get a Blackfin camera if funds will be available), a MaxSonar EZ4, a few Sharp IR sensors, a few contact sensors for the mechanisms inside. Right now the whole thing is on paper, I'll CAD latter when everything takes shape.
The parts I need will be made from 3/8" plexiglas, so I can tap screws on the side. Some parts will be thinner.
But I need a special part that needs a four axis CNC. It is a pipe that has teeth on an end to make a crown gear. This will be the forearm of the robot and it needs to rotate. A pico servo will have a small gear on it's spline will be mounted to rotate the pipe. Another pico servo will be mounted inside the pipe to actuate the fingers (gripper style, but with 3 fingers). The pipe diameter will be around 3/4" (or whatever I can find close to this diameter, but not smaller). The pipe lenght will be around 2-1/2", that needs to be determined. A smaller diameter pipe will be mounted at the non toothed end and will hold at it's other end the fingers. There will be 2 such arms on the robot.
Any advice from experienced CNC fellows will be greatly appreciated. If this doesn't get too expensive, I will probably need the parts done the latest at the end of september.
Thank you in advance.
