XSCC20 Blow-up

OricomTech Bot-CoP Servo Control Computers are designed for controlling multiple R/C servos and small mobile robotic devices. Up to 20 servos can be controlled via a single RS-232 serial port. This is enough capability for most robotic walker and animatronic devices. Firmware is upgradeable.

The XSCC20 Servo Control Computer uses the BOT40-II Controller Board as a platform. It has basic core elements of power supply, cpu, RS-232 port and serial eeprom, as well as a large prototyping area that can be customized for many different types of applications. The board can interface up to 20 Futaba-pinout R/C servos. It also has space to add a 5-Amp voltage regulator for driving a limited number of servos.

XSCC20 Commands

New features in firmware version 2.0 (01.2005)

new binary command format: (escapecode, servo#, pulsewidth), etc.
both 1-usec and 4-usec pulsewidth resolution binary commands.
binary commands set ramping speeds.
storable configuration: baudrate, enabled servos, servo starting positions, etc.
servo cycling mode - for servo testing.

Original firmware support:

control up to 20 servos.
255 ramping speeds.
up to 29 digital I/O lines.
up to 8 A/D channels.
powerful ASCII Command Set.

General Features

servo support:

---- interface up to 20 R/C servos - 3-pin Futaba pinout (signal, power, gnd).

---- set pulsewidths from 500 - 2500 usec, with 1 usec resolution.

---- select individually-controlled ramping velocities, from 2 - 500 usec/step.

---- select servo update periods, from 10 - 30 msec (default = 20 msec).

---- servos updated sequentially - all servos updated within 20 msec.

alternate I/O:

---- allocate up to 29 lines for digital I/O.

---- 8 A/D conversion channels (10-bit), available while simultaneously driving up to 20 servos.

special features:

---- software incorporates a low battery voltage shutdown feature.

---- external trigger sources can be used to enable servo operation.

pcb features:

---- pcb mounts (2) TO-220 voltage regulators, with heat sink.

---- prototyping area for custom circuitry - allows addition of discrete components, sensors, conditioning circuitry, etc.

board communications:

---- RS-232 at 1200 - 115200 bps.

---- interface via DB09-F connector.

---- simple and powerful ASCII command set.

Power

input power 8-15 vdc at 20 mA for controller.

5 vdc, 1-Amp, TO-220 regulator used for logic, driving external sensors, etc.

power for servos normally provided from off-board.

pcb has space to add a 5-Amp voltage regulator for driving a limited number of servos.

includes space for heat-sinks on both regulators.

Physical

3.0" x 3.6" (76 x 91 mm), industrial-quality double-sided FR4 pcb with heavy buss traces, plated-through holes, solder masks and silk-screens.

mounting hole at each corner (#4 screw).
