Control Board Progress

Today we were able to cut out the polycarbonate for a control board on the CNC router at Glendale Community College.  It took much longer than expected, due to the polycarb melting at any feed rate over 18 IPM, even with a constant cool air blast on the endmill.  Machine setup took about 75 minutes, and fixturing, cutting, and removing the panels took about an hour.   Tomorrow evening we will finish cutting the second board.  Below is a picture of the assembled control board.

Weekend Progress: Update

The manufacturing department was very understaffed today due to the superbowl(I guess?)

We’ve completed the milled slots on the 1 x 2 Arm sides(1010084)

Weekend Progress

Manufacturing:

Tonight we completed the four piston bearing blocks (1010073) for the kicker winch.  These took much longer than anticipated using manual machines.   Below is a picture of the completed parts:

For the small piston bearing blocks (1010019) we hope to have a CNC lathe available tomorrow evening.  Tomorrow we hope to cut out the control boards as well, on a CNC router.

The 1 x 2 x.125 box tube parts for the arm structure have been cut, and are currently undergoing milling and drilling operations, and preparation for welding this week.

Bumper Mounting and Control Board Parts

Today we completed the 32 bumper mounting pins and brackets, and 20 control board spacers.  The bumper mounting scheme is nearly identical to the 968 2009 bumpers.  The finished parts are shown below.

Next, we hope to cut the control board polycarbonate on a CNC router, and machine the piston bearing blocks (cones) on a CNC lathe.  Additionally, we will be cutting the 1×2 box tube parts needed for the arms.

We haz powdercoat.

We haz powdercoat.

Unfortunately, Central Powder Coating was not well staffed today. They will have the 254 frames powdercoated blue streak #2 tomorrow morning.

We will be picking up the blue frames tomorrow at 10AM.

Revised Control Board Layout

This revision includes the cutout for the Classmate pc, contours and filets for the ethernet jack, holes for the LED mounts, screwdriver slots for the Cypress board and finally, an additional cutout that replaced the roller button.

Progress

Manufacturing

Pacific Precision is able to make the output shafts; unfortunately they will not be done until late next week. We also confirmed that the robot frames will be ready to be picked up from Central Powder Coating at the end of business day Thursday.  We continued progress on machining the bumper mounting pins, and will begin on the kicker piston bearing cones once the bumper mounting parts are complete.

Design

The control board CAD is being revised and we purchased all of the components for the boards.

Other News

We secured a local embroidering shop to make the team numbers on the bumpers.

We have contacted Motion Industries for a quote for all the ball bearings, and are currently awaiting word back.

Welding Complete, Off to Powder Coat

Today the welding was completed at Ride & Show Engineering, and the frames were delivered to Central Powder coating. The picture below shows us with the kind folks at Ride & Show.

Control Board

Update: Here’s the newer revision of the control board. I’ve added an ethernet port and a female barrel plug for the Classmate PC.

Here’s the first revision of the control board with a suggestion of buttons and functions.

We will be using this LED w/Defuser(Red and blue??)

Robot Chassis Ground

Here’s a few shots of the welded base after having the welds ground flush.
