Right now, the way it is geared, it takes about 12 seconds to fully raise. It seems a lot, but when you watch it, it actually seems quick. It used to be much faster, but I geared it slower to make it easier to control.

that robot is amazing, how much does it weigh? also what kind of sensor is pointed at the mini vision tetra?

According to JVN, the linear bearing pieces may be available for purchase from VexLabs sometime in the next month or so. They are brand new pieces, that work excelent and have very low friction. They are 12 inches long, and comprise of an inner and an outer metal bearing piece. Here is another picture of them:



Right now, the robot weighs about 7 pounds. The sensor pointing at the mini vision tetra is the Vex Ultrasonic Sensor. I was using it to try to find the panels on the side of the vision tetra in autonomous, but with limites success. Even though it pans back and forth, the angle of the vision panels deflects the sound pings away. Unless the sensor is dead on, it never gets back a good reading because of the geometry of the vision tetra.

How long will it be before I break the six-foot height for Vex?
