Build a very tiny, affordable replacement board for the hexbug spider and transform it into a programmable micro robot.
If i do this project i clearly want to have a few arguments why someone should use this solution against many other existing "programmable Robots".
Hexbug has it's own programmable robot kits called Vex Robotics. There are different flavors of these kits.
The simple Vex Robotics construction kits are more toys than robots. There are three models which can be assembled with a click-style system. The "programming" is done via a switch matrix which allows for 64 different "programs". Basically you can route two sensors to two actuators, e.g. make left motor turn backward when sensor 1 is triggered and LED lit when sensor 2 is triggered.
The more advanced Vex IQ or Vex EDR series target the educational sector like schools or universities. Here you get the full freedom of building and programming. Of course the price tag is much higher.
