7:00 to 9:00
Still need a chairman's officer
Tonight: Half-hour to finish assembly.
Professor Jack - Lessons Learned
Most of the robots fell apart during the course. Reliability
The wiring. The controls were not intuitive.
The team that won finished earlier and had the most driving practice.
The wheels were all cantilevered. The farther out the wheels are, the more force is upon them.
It is best to learn these lessons now.
Homework from Professor Lavery.
Due next week.
Using existing robot design, solve questions.
*What is the maximum possible speed of your robot? (max Drill RPM = 550)
Maximum theoretical. RPM = 550 Diameter of the wheel = measure it
Ask members of your small team. Ask teachers. Use your available resources to find out.
*What is the side load on the drill?
Weight of robot. Standoff distance from bottom of the wheel to support point of drill.
*Where is the CG of your robot
*What is the maximum your robot can pull? (Drill power = Max 0.1 HP)
Theoretically at speed. Assume frictionless.
*How would you improve each of these?
