| This first version of Golias is a prototype of a more robust unit. Its finality is remote vigilance. I will then apply what I learn from it to the final version.
In the first stage, Golias is tele-operated with a 14 channel modified remote control that I made with a PIC16C84. It transmits the control in PWM or serial (RS232) mode using Telecontrolli RF modules operating in 433MHz. Another RF module operating at 345MHz is
installed in Golias for telemetry. In this stage only a PWM (Pulse Width
Modulation) control is used. A BasicStamp2 reads some outputs of the RC receiver and
the sensors to avoid obstacles or stop the robot if a control signal loss
occurs. The motor section has two "big servos" modified for continuous rotation. This
section is fully modular enabling the motor to be changed to a more powerful
unit by changing the motors support. |
