Robotic Arm 6 DOF Assembly Guide
Overview
:
6 DOF Robotic Arm from Robokits is a robotic arm with 4 degrees of freedom joints and a
Gripper. Its act ated sing 6 Standard size servos o t of which 4 are normal Nylon gears
standard and 2 are Metal Gear High Torq e servo motors.
This robotic arm is controlled by USB (optional wireless Bl etooth) Servo Controller. It and be
controlled by PC or other microcontrollers.
The power req irement for this robotic arm is 5 to 6V DC 10 Amp power s pply. It co ld be
either battery or a AC power s pply rated at 5-6VDC. Yo can also se a modified comp ter
SMPS s pply, it is available for sale on Robokits website and yo can also modify it yo rself if
yo have one. There are many t torials available for these modifications on internet.
Before starting the assembly we recommend to read the doc mentation of Servo Controller so
that it will be easy to nderstand all electric connections and controls. If yo have this
doc ment on CD then it sho ld be in the same folder as this doc ment otherwise yo can
download it from here:

After assembling the robotic arm yo will be able to control it from a Windows PC. However if
yo want to control it with a microcontroller yo can directly generate C code for it from servo
controller software. This generated code is directly programmable to o r Rhino Robot Control
Board or Ard ino, if yo want to se other microcontroller or compiler it co ld be translated
easily if yo are good at C lang age and embedded programming.
Let’s start with the basic assembly of robotic Arm. Some basic tools like screw drivers,
pliers, small spanners, soldering iron, wire c tter, nipper, stripper are req ired to complete the
assembly.
The notations sed in this doc ment for screws, n ts & bolts are like these.
1. 3x6 mm cap screw – 3mm small screw
2. 3x8 mm cap screw – 3 mm mid screw
3. 3x10 mm cap screw – 3 mm big screw
4. 3x8 mm CSK head screw – CSK screw
5. 3 mm Nylock N t – Lock n t
6. 3 mm n t – n t
