How to read analog values and output analog voltages with CircuitPython. Learn about analog to digital converters, digital to analog converters, and pulse-width modulation (PWM) outputs that can approximate analog outputs.
Reprise of Tony D’s talk from World Maker Faire 2017 and Seattle Mini Maker Faire 2017, “Make With Python”. Learn about interesting hardware that you can program with the Python programming language. This talk describes what is the Python language and why you might want to use it instead of other languages or tools like Arduino. There are live demos of blinky things powered by Python code!
Meet the four VEX IQ robots that you can build with a Starter Kit or Super Kit! Armbot IQ, Clawbot IQ, Ike, and V-Rex!
The VEX IQ Controller uses joysticks that may occasionally need to be calibrated for proper robot function. To access the controller calibration process, tether a Controller to a Robot Brain, press the “X” button on the Robot Brain home screen to access the settings menu, and select “Calibrate Controller.” Rotate each joystick 360 degrees. Video updated in November 2014 to include instructions for Robot Brain Firmware v1.13 and Controller Firmware v1.04 (or higher).
Gear ratio can be used to adjust the speed or torque of a mechanical system. With the VEX IQ gear ratio simulator, learning about different types of gear reductions is easy!
The basic concepts of speed, torque, and mechanical advantage are essential to engineering and robotics. Learn about their relationship using the VEX IQ robotics platform.
The VEX IQ Robot Brain, Controller, and sensors run on special software called firmware. Firmware is periodically updated to include additional functionality or fix bugs.
VEX IQ’s tool-free construction system enables users to attach and remove pieces without the need for additional tools. Sometimes, small gears or pulleys may seem difficult to mount onto shafts, but a little leverage is all that’s needed to get them on.
Choosing the right piece to build a VEX IQ robot is important, especially when it comes to selecting the correct angle beam. This video provides some advice on identifying similar angles.
VEX IQ’s tool-free construction system enables users to attach and remove pieces without the need for additional tools. In order to create robust drivetrains or other mechanisms, make sure you properly support your motor shafts!
VEX IQ’s tool-free construction system enables users to attach and remove pieces without the need for additional tools. Sometimes, connectors or pins can seem a bit tough to remove, but a little nudge from behind is all that’s needed to break them free.
Pairing a VEX IQ Controller to its Robot Brain only takes seconds and allows you to drive your VEX IQ robots!
The VEX IQ Smart Motor uses its built-in quadrature encoder to consistently control time, revolutions, speed, torque, degrees of turn, and more.
The Bumper Switch that comes in every VEX IQ Super Kit or Starter Kit with Sensors works out of the box with some pre-loaded functionality – bump it to limit robot motion!
The Touch LED sensor that comes in every VEX IQ Super Kit or Starter Kit with Sensors works out of the box with some pre-loaded functionality – touch it to make a robot start or stop!
The Color Sensor that comes in every VEX IQ Super Kit or Starter Kit with Sensors works out of the box with some pre-loaded functionality – show it green to start or red to stop your robot!
The Distance Sensor that comes in every VEX IQ Super Kit or Starter Kit with Sensors works out of the box with some pre-loaded functionality – it will prevent a robot from backing into a wall!
The Gyro Sensor that comes in every VEX IQ Super Kit or Starter Kit with Sensors works out of the box with some pre-loaded functionality – your robot will remember which direction is forward!
