Servobotics Robotic Arm Model RA-02

Robotic Arm Kit (Manual & PC Windows Control)

Robotic Arm RA-02 Six Servomotor Robotic Arm Kit includes:

6 Servomotors
Servomotor Brackets
Robotic Arm Base
Servomotor Reverser
Servomotor Gripper
Servomotor Controller Kit
includes: PCB and components
Instruction Manual
CD with Windows Programs

The RA-02 Robotic Arm teaches basic robotic principles. The RA-02 kit includes all components necessary to build the robotic arm shown at left.

The robotic arm kit also includes the SMC-05 servomotor controller kit. The servomotor kit includes the pcb and all components necessary to build the servomotor controller (soldering is required). Using the 5-position servomotor controller see picture below one can control the robotic arm using the onboard three position switches to manually to grab, lift, lower, wrist rotate and pivot.

In addition the Windows (98/XP) control software Free Download Available! allows PC control through one of your PC's serial port. The windows program has a script writing feature that allows one to program the robotic arm with thousands of movements with full, precise and repeatable control of each movement. Scripts may hold a maximum of 10,000 movements (including pauses) with a maximum repetition of 10, 000.

PlayStation PS2 Servomotor Controller Interface

Images Scientific Instruments Inc. PS2 PlayStation Servo Motor Controller Interface allows manual control of six hobby servo motors using the PlayStation PS2 (Wired or Wireless). (Hitec/Futaba) [Not Included].

PS-SMC-06 PlayStation Servomotor Controller

The servomotors are controlled using the two joysticks on the controller. X and Y direction of each joystick each controls a servomotor. This totals four servomotors. To control servomotors numbered 5 and 6, one presses and holds the left shoulder button, while using the right joystick.

Servomotor speed is proportional to the tilt of the joystick.

Rumble feature activates when servomotors reach the end of their rotation in both the clockwise (CW) and counter clockwise (CCW) rotations.

New Mobile platform mode.
In this mode Servomotor1 and Servomotor2 are configured as differential drive in a moving platform using Continuous Rotation Servomotors see illustration below. See manual (PDF 270K) for complete descriptions of modes available.

Integrated Power Supply (IPS)

Our new IPS (Integrated Power Supply) line of servo motor controllers allows you to use a variety of inexpensive power supplies to run both your controller board and servomotors. Use available power supplies; transformers, batteries, wall transformers, etc. anything from 6V to 30V either AC or DC. The IPS system will regulate the power to run your servomotors efficiently. Power is supplied through 2.5mm power socket on board.
