This kit is intended to be the base platform for your education into robotics. Please take the opportunity

to expand your robot to do many more functions.

Additions you can do:

Mount a 9G servo between Level 1 and Level 2 for controlling an ink Pen or Marker to go UP and Down.

Mount a standard servo or 9G servo at Level 4 ... for whatever you want.

Use the extra mount areas for the HC-04 BlueTooth, ESP 8266 Wifi, Accelerometers, Gyroscopes, Dual Relay board ... etc.

Mount a voltage regulator for powering the L298 motor controller. This means that friendly

competitions become about who has the best code, not about who has the best charged batteries.

Mount encoder wheels and quadrature opto-isolators to track your wheel movement.

Projects:

Play musical beeps

Random dance movement with beeps

Display the motor command speed while moving

Display the Ultrasonic distance on the display

Detect the wall to avoid hitting it

Wave a flag as you drive around

Use the robot to draw “Spirograph” art

Connect to a network and host a web site

Control the robot from a PC web site

Control the robot from a PC application (using UDP network communications)

Control the robot from your tablet or cell phone
