Final RA SG2

What is one of the most important mechanical problems to overcome in any robotic system?

• Gear ratio
• Material configuration
• Friction
• Pneumatics

How will the torque and power of a robot be affected if the tire size is increased, but the driving gear ratio stays the same?

• Slower take off speed – Faster top end finish
• Faster take off speed – Slower top end finish
• Larger the tires – slower the bot but torque power is increased
• No change in power, torque, or speed – the gear ratio stayed the same

There are lights on the joystick and micro-controller to the robot for feedback purposes.  What does a yellow light on the micro-processor and a green light on the joystick mean?

• The joystick is not providing the micro-controller with enough power
• The joystick is sucking to much power from the micro-controller
• Weak batteries in the micro-controller
• There is only 10 minutes of system power left

What is the equation for calculating the speed of an object?

• Velocity / Distance
• Velocity / Time
• Rotational Cycles / Distance
• Distance / Time

When a robotic arm is constructed, what relationship to the robot base must always be accounted for?

• The traction ratio
• The center of gravity
• The strength of the end effector
• The increased motor amps

What is a robot mechanism designed to pick up a large number of similar objects?

• Gatherer
• Transducer
• Accumulator
• Object Grouper

End effectors are generally used to pick up things, so what is the typical gearing found in robotic arms?

• Geared down for power
• Geared up for power
• Usually remain neutral 1:1
• Compound gears are never found

What is the first rule of brainstorming?

• Only do it if there are at least 3 people
• Good brainstorming will allow analysis to be skipped
• Never allow outlandish ideas to be spoken
• No idea is a bad idea

Your robot just spins its wheels and goes nowhere – what might be done?

• Add weight
• Change the gear ratio
• Change the tire type
• All the above

You have a robot that keeps getting hung up at a narrow spot of a maze.  What might be done?

• Install sonar sensors
• Get a more accurate controller
• Increase the speed and plow through
• Install a robotic arm
