pic: 701's Robot so far



Here’s a pic of our entire 2007 robot so far. We’re still testing a lot of programming and such. But the quick run down is …

  1. 2 CIM BaneBot 12:1 transmissions on each side
  2. 2 KOP 6" Wheels in the center, and 4 AM Omni’s in the front and back. #35 chain all around the drive with simple UHMW eccentric tensioners.
  3. Center section telescopes using 2 globes acting as a winch with nylon straping doing the lifting.
  4. Single jointed arm powered by two window motors - we tried 1:1 chain drive today and it didn’t work to well and are changing it to 1.6:1. 25 Chain on the arm.
  5. Grabber is actually two actuators modeled after our 2005 bot. One cylinder pushes out a “bayonet” that helps support the base of the tubes. Another cylinder actuates a grabber to come across the top of the tube. When the “bayonet” is retracted, the tube falls straight down, hopefully on a spider leg.
  6. There are also two ramps not shown in this pic. They can pick up two 150 lb robots using a kickstand device powered by FP/BaneBot motors.
  7. There is a mount for a camera which is behind the telescoping section. We still need to program and test this.
  8. We have 63k64 encoders on each drive transmission and a 61k128 encoder on our telescoping section. We also are using a standard Potentiometer on our arm.
  9. We are using PID on the telescoping section and a smoothing algorithm for driving to lessen damage to the 54mm BanBots.

The robot as shown in this pic weighs in at 94 lbs.

Looks awesome, love the arm.

Here’s something funny that happen to our arm last night…

We’ll find a better way to attach that section to our pnuematic!!

hmmm, what’s the projectile rule like this year? :smiley:
Looks like you guys are getting to the practice phase (only to be interrupted by some sucessful programming right?)
