(KSR4)

The Escape Robot Kit works just like an A.I. robot. It never fails to find its way out of a maze. The Escape Robot uses 3 IR emitting diodes and 1 IR receiving module to send and receive signals and detect obstacles.
The Escape Robot's built-in microprocessor enables it to "think" on its own: it gathers and processes information on its environment so it can avoid any obstacle. The Escape Robot moves about on 6 legs.
This kit comes complete with 2 sets of differently designed legs that move in their own distinct way.

• dimensions: 140 x 150 x 100mm

Scarab is a robot that uses 2 touch sensors to detect obstacles. When its antennas (touch sensor) detect an obstacle, Scarab will first step back and then automatically execute a two-step manoeuvre to avoid the obstacle. The manoeuvre is a combination of "left turn", "right turn", "reverse" or "stop". The Scarab Robot can be configured with different sets of movements.
The Kit comes complete with 2 sets of differently designed legs, which move in their own distinct way.

• dimensions: 175 x 145 x 85mm

Remote Control Units

 $49.20

Kit 157 Rolling Code 2-Channel UHF Remote Control
This is state of the art. Up to 15 Tx units can be learnt by one Rx unit.

$55.80

K180 Kit 180 Rolling Code 4-Channel UHF Remote Control

$62.40

K181 Kit 181 Rolling Code 10-Channel UHF Remote Control

Kit 181 uses the same Tx/RX pair as Kit 180 but it uses all 10 defined keypress combinations out of the 4 buttons to activate relays. The following keypress combinations give readable outputs: pins 1, 2, 3, and 4 (of course) and the pins 1&2, 1&3, 1&4, 2&3, 2&4, and 3&4 pressed together. A PIC16F628 does ALL the work. It is a perfect demonstartion of how micro-controllers have taken over from cmos logic etc.

Toggle or momentary mode will be determined by keeping the 1 or two buttons depressed for more than 2 seconds and then that relay will stay in that mode until another >2 sec keypress. Small relays are used to save weight and board area.

K186 Kit 186 Power Amplifier D.C. Supply

This is a DC power supply board designed for our Kit 106 audio power amplifier. It is also suitable for any power amplifier module or circuit requiring a positive and negative rail voltage of up to 45 Volts per side. The output voltage and current will depend on the transformer chosen, and this is not supplied with the kit. Never use a transformer larger than 35V-0-35V, as the capacitors voltage rating will be exceeded.

Kit 187 Stepper Motor Drive

The Stepper Motor Chopper Driver is a Bipolar Stepper Motor Drive with easily adjustable current control up to 2A, based on the SGS-Thompson L297 and L298 stepper motor controller and driver IC’s. 

Stepper motors are rated by current and and not by voltage.  A chopper driver because it is  switching on and off current allows a set current to be fed to the coils and not be dependent on the voltage of the power supply.  The Chopper Driver also allows for the use of higher voltage power supplies (up to 36V) to overcome the effects of the inductance of the coils giving better performance and a higher top speed.
