## Description

"Young engineers will be delighted with the new HydroBot Arm Kit. It is powered by water, so no motor needed! They can use the levers and the power of hydraulics to move the multi-axis arm. The lever controllers have a special braking system that helps to achieve fine, accurate tasks. The gripper can open and close with a maximum 47mm (1. 89 in. ) gap, wrist joint rotation of 180deg. , wrist joint mobility of 98deg. , elbow joint range of 44deg. , base rotation of 270deg. , and shoulder joint motion of 45deg. , with a vertical reach of 16. 35in. , horizontal reach of 12. 42in. , and 50g lifting capacity. Grippers can be removed and replaced with suction components to pick up objects with smooth surface areas of no greater than 50g (1. 75 oz. ). The clear, animated instructions make the assembly and operation of this STEM robot easy to understand. Best suited for Future Engineers 12 and up. Elenco Teach products are based on STEM activities (Science, Technology, Engineering, Math) to teach and encourage kids in their development, all while having fun! All Teach Tech Green-Energy robots are powered by either water, wind, or sun, so there are no batteries required. Perfect for future engineers ages 12+. "

## Questions & Answers

**Q: Is there a way to get replacement parts? My child is really enjoying building this robotic arm, unfortunately some of the tiny parts are lost**
A: Horrible customer service  with the  company, don't offer replacement or replacement parts. Told us to use zip ties to hold it together. Biggest waste of money and a piece of junk. Wouldn't recommend

**Q: Why are there two different prices for this product? One is $37 and the other is $59... I don't see a difference in either product. Please help!**
A: The product is being sold from two different vendors. Teach Tech is our brand.

**Q: How many pieces**
A: Thank you for your inquiry. There are more than 230 parts in this kit. I hope this helps!

**Q: Arm not working , my son build the arm but the front part or the claw does not pick up stuff**
A: hi its actually for me a con. my son is 12. very difficult to assembly and its not a robot! if the arm doesn't work its a pain. it means there is air in the tube so he has to desassumble it, get rid of the air using 2 water sources for each end of the tube and then reassembly it.  as i said we were very dissapointed with the product. however its very educative in terms of engineering!
