Excellent design - makes a great tool in other projects Dec 08, 2010
By Mr. Robotica
Cleaver and flexible design, it lends itself to easy modifications (increased the motor torque, modifications to the griper etc.) and adaptations for use in other projects. Such as a third hand on my electronics work bench when soldering etc. I just bought a second one.

 Mr. Roboto Nov 08, 2009
By Steven Hageman
"Hagtronics"
I bought this as a robot project to do with a 4th grader. It is well documented and the parts are well laid out in the box so they are easy to find. The 4th grader had no real issues following the instructions (with my little hints along the way). It works very well - the rotating wrist is pretty cool and a unique feature of this robotic arm. All in all a fun kit.

Key Points
*Relatively high cost ($65-$120 USD)
*extremely low speed (at acceptable torque, even at unacceptable torque!)
*delicate assembly
*good lifting power if tuned properly
The OWI-007 Robotic Arm Trainer is a pretty neat product but the low speed and joint limitations set it back from nearly every other robotic arm on the market.
The arm works with a 5-channel remote corresponding to five DC motor (RE-240) gearboxes that come pre-assembled. The rest you have to do on your own. It's a great learning experience, building the arm, especially for older children and young adults.
The chief problem lies in the clutch/slip gears, which must be carefully tightened down (using the provided tapping screws). Over tightening or under tightening, even a small amount, could result in the arm not being able to lift anything (even it's own weight). The shoulder joint has the most problems with this. However, when the slip gears are tightened properly, the arm can lift weights in excess of 400 grams!
I tend to compare this arm to others in its' range; i.e. the OWI-535 Robotic Arm Edge. The OWI-535 excels in nearly all aspects save two. *The clutch gears must be modified (super glue or other) to lift over 350 grams (use care in operation).
*The wrist does not rotate left/right it only moves up and down with limited articulation.
Overall I rate the OWI-007 Robotic Arm Trainer a 3 star. It's a cool teaching/learning project but in the long run falls short of what it could have achieved.

Fun To Build and Play With Mar 03, 2011
By A. Wear
I bought this robotic arm to learn more about servos and motion. I already own an OWI-535 Robotic arm which uses a tilt motion at the wrist. This arm has twist motion at the arm. The base will spin freely when carried and that is the only thing I don't like about it.

Lots of assembly required Feb 13, 2009
By John Wooden
When I bought this I didn't know it was a "kit" and it was pretty amazing. Luckily it is laid out well in the box so if you don't get ahead of yourself you will be able to figure it out. It's certainly educational and fun once you get it adjusted correctly. It's a little pricey too.
