Google Leave Day 17: June 17, 2009

I showed my robot to Dan before he went to school. He suggested to attach right-angle gussets to the robots feet to prevent the wobbling motion. I did it.

I took the big car to fix a flat tire.

I showed the walking robot to Mr. Mark Snow and a few of the Summit High School Robotics team. They said it was cool. They made several suggestions to prevent the wobbling motion of the robot:

• Attach the gears of the two legs of the same side to the same axle instead of different axles. The force will be applied to both side of the axle, which should reduce wobbling of the gears.
• Connect the two legs of the same side using a device similar to bicycle pedals, so they legs will not move apart too much.

I suggested the following modifications:

• Reduce the slack between the legs and the gears by adding another washer. However, the screw should not be tight to allow free movement of the leg around the gear.
• Replace the gear hubs from a free rolling hub to standard gear hubs to reduce the slack of the gears relative to the axles.

I got the iMac I ordered for Dan. He moved his home directory to the new computer and set it up. The new iMac should reduce the contention on the old iMac between Dan, Shirley, Rena and Imma by moving the heaviest user (Dan) to his own computer.
