Solar car (Photoelectric) 2003 A model for a school project. Features include two 1 Farad supercapacitors which give an ability to charge in relatively low light and also to drive about 10 yards through a shaded area out of direct sunlight. The solar panels can be tilted to either side to best catch oblique sunlight. Two LEDs indicate the charging with the high intensity blue LED being visible in sunlight. It can be charged in low light from a light bulb.

Robotic car (PICAXE programmable) This model car is programmed via a PICAXE 28A chip 168F72 with Basic language. Transfer of the program is via a serial cable output. It is simple enough for kids to be able to program. The 4 MHz development board has 8 outputs buffered on board by a darlington driver chip ULN2803A and a L293D motor driver chip. There are 8 inputs and 4 analogue inputs as well. It all runs on 4.5 V. There is a 256 line limit and 15 gosub limit Mechanically it has two independent rear motors and a front castor (a small furniture one) all mounted on a 23 x 17 cm acrylic chassis.
So far it has inputs of 2 switches and a light dependent resistor and outputs of two motors and two LED's. |
