It is a very simple and easy to make device. The whole process takes only few hours.
The robot is made of two wire types: from the bicycle spoke and thinner copper wire. Everything is soldered together. Dampers and blue connectors move along the frame and change the position of bipolar switch. Change of the direction of RPM is based on reversing the power poles by the switch.
The device is powered by a Li-Ion battery from a phone. It lasts for hours of the robot's performance. It is turned on by the jumper switch. It can be easily loaded by taking the jumper off and connecting the charger. The AC is controlled and stabilized with current limit.
