MSCC20 Blow-up
[to MSCC20 page 2]
OricomTech Bot-CoP Servo Control Computers are designed for controlling multiple R/C servos and small mobile robotic devices. In the basic version, up to 20 servos can be controlled with a single credit-card sized board via a single RS-232 serial port. This is enough capability for most robotic walker and animatronic devices. Firmware is upgradeable.

The Servo Control Computers use the SBOT28 Controller Board, plus one of our Bot-CoP - Servo Coprocessor chips, to create a complete servo control solution. The controller card is sold separately as the SBOT28 Controller Board. 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.

MSCC20 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 20 digital I/O lines.
  • up to 5 A/D channels.
  • powerful ASCII Command Set.

Applications

  • general servo control
  • robotic arms
  • robotic walkers
  • animatronics
  • motion devices
  • models

    General Features

  • tiny, credit card-sized board for compact designs.
  • 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 pulse update periods, from 10 - 30 msec (default = 20 msec).
  • ---- servos updated sequentially - all servos updated within 20 msec.
  • alternate I/O:
  • ---- allocate up to 20 lines for digital I/O, or 5 for A/D conversion (8-bit).
  • special features:
  • ---- software incorporates a low battery voltage shutdown feature.
  • ---- external trigger sources can be used to enable servo operation.
  • pcb features:
  • ---- pcb mounts TO-96 or TO-220 (with heat sink) voltage regulator
  • ---- brown-out circuit accommodates momentary power surges.
  • ---- large prototyping area, comprising 50% of pcb area, for custom circuitry - allows addition of discrete components, sensors, conditioning circuitry, etc.
  • board communications:
  • ---- RS-232 at 1200 - 115200 bps.
  • simple and powerful ASCII command set.

    Power

  • input power 8-15 vdc at 20 mA for controller.
  • 5 vdc, 1-Amp, TO-220 regulator can be used for driving external loads.
  • power for servos and driven devices normally provided from off-board, via pins on main header.

    Physical

  • 2.15" x 3.5" (55 x 89 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).
