Examples of practical applications of BASIC Stamp controller

Some applications of the BASIC Stamp controller: 

…. Chalmers University of Technology, Sweden - lab robot camera- you can see whats happening in their laboratory over the web. http://mac5.pe.chalmers.se Hugh MacMillan Rehabilitation Centre, Toronto, Ontario, Canada, has a project using the STAMP to control an artificial hand for young amputees Some applications of the BASIC Stamp controller

Physical Design of the Airship: 

Physical Design of the Airship One or more spherical balloons A plastic gondola to house the electrical equipment Helium used to fill the balloons

How it Works: 

How it Works User gives commands through a PC keyboard These commands are relayed through the RF transceivers to the blimp The blimps on-board intelligence interprets the commands and performs the corresponding functions

The Ground to Air Transmission: 

The Ground to Air Transmission The Basic Stamp II gives the transmitter the appropriate bit pattern The On-Board Stamp then receives the bit pattern from the receiver Based on the bit pattern received, the Stamp will set the appropriate bits high or low

Slide13: 

The Motors The On-Board Stamp is interfaced with the motor driver circuit Propeller motors are used There is an enable and a fwd/bwd signal for each motor

Onboard System:

Problems to solve: 

Problems to solve reverse directions of two motors at particular points in their travel ensure that the moving arms don’t become and remain synchronized

PIC is used to:: 

PIC is used to: check when the motors have hit their CW and CCW limit switches reverse the motors’ direction add a little delay to the time it takes one of the motors to reverse directions in order to prevent synchronization

Slide49: 

#include <12c509.h> #use delay(clock=4000000) void main () { set_tris_b(0b001111); //four lines are inputs, two are outputs while (1) { if(input(pin_B0)==0) // if cwLampLimit is touched {output_high(pin_B4);} // activate lampMotorRelay} if(input(pin_B1)==0) // if ccwLampLimit is touched {output_low(pin_B4);} // de-activate lampMotorRelay} if(input(pin_B2)==0) // if cwShieldLimit is touched {output_high(pin_B5); // activate shieldMotorRelay delay_ms(500); } //wait half a second to ensure //non-synchronous movement if(input(pin_B3)==0) // if ccwShieldLimit is touched {output_low(pin_B5);} // de-activate shieldMotorRelay} } }
