Mark III Chassis Kit

Includes Chassis, Scoop, Battery Holder, Screws, Nuts, Washers - everyting you need to biuld a platform base for a small autonomous or competition robot.

Supplied without wheels and servos.

GWS S03N 2BB Servomotor

GWS Standard-torque Ball bearing servomotor. This motor has two ball bearings, generates 47oz/in of torque, and is easy to modify for continuous rotation. This is the same sevomotor that's included in the Mark III complete robot Kit.

Mark III Controller Board Kit
OOPIC Version

Mark III Controller board. Includes all the parts needed to build an autonomous robot controller. Buy this item if you already have a robot base and motors, and just need the "brains". Assembly required.

Mark III Prototype Board Kit

Prototyping mezzanine board - mounts on top of Controller board, providing access to all 40 PIC pins (except for the oscillator in/out pins). Has ample prototyping space for through-hole components - supports .3 and .6inch DIP packages.

Mark III Sensor Board Kit

Expansion Module. Comes with the minimum number of parts needed to make the Expansion Module functional: 1 bare PCB, 1 6-pin stacking header, 1 40-pin stacking header, 2 3-pin servo headers, 1 22 KOhm resistor network, 1 PCF8574 I2C Expander, 1 5pin I2C connector, 1 6-position DIP switch.

Accelerometer Kit

Requires Expansion Module Kit

Analog Devices ADXL202E 2-axis acceloremeter. It measures accelerations between -2g and +2g, and can be used to detect tilt of less than 1 degree in any direction.

H-Bridge Kit

Requires Sensor Board Kit

Add four 1A DC motor drivers to your Mark III sensor board. Kit includes 2 Texas Instruments SN754410NE dual H-bridge chips, 4 green LEDs and 4 red LEDs to indicate motor direction, 4 1KOhm pull-up resistors, 1 74HC04 hex inverter, and 4 3-pin motor headers (Handy Board pinout).

PIC Microprocessor with PICLoader

PIC 16F877-20/P microprocessor. 20MHz clock speed. 40-pin DIP. Pre-programmed with Rick Farmer's PICLoader bootloader. This is the same chip bootloader used in the Mark III kit.

256Kbit I2C EEPROM

Microchip 24LC256 serial (I2C) EEPROM. Holds 256Kbits, or 32K x 8bits. Required when using the OOPic chip on the Mark III controller board. Useful even in the standard Mark III configuration, since this provides a large amount of user-writeable space. Store maps, or state tables for your robot.

OOPic II+ Upgrade Kit

OOPic II+, 256Kb serial EEPROM, 8pin socket, two shunts. Lets you turn your Mark III into an OOPic-based robot, or use your Mark III Controller Board as an OOPic development board.

Mark III Robot Kit
(OOPic Version)

The Mark III Robot kit includes everything you need to build a complete autonomous robot including controller board, sensors, microcontroller, chassis, wheels, motors, documentation and software. Just add batteries. Assembly required.
