SainSmart 17DOF Biped Black Educational Robot Kit with Servo Bracket Ball Bearing for Hobbyists, Robot Competition, Kids

If there was an option to give 3.5 stars I would.The good:All the pieces were there. There were plenty of extra screws. Everything went together as it should have.The bad:Plan on setting aside a lot of time to put this thing together. A hefty task that is made even more difficult by the fact the instructions are poorly done. Some pictures are more clear than others as to what goes where. Over all they are poor but I did manage to successfully assemble the robot so they do get the job done. Lastly, they suggest using MG996R servos for the lower half joints. The ones I bought from Tower Pro are terrible. They do not center very well, are noisy, slow, and 2 out of the 17 I purchased lock up. I replaced them with Hitec HS-5645MG servos which happen to be 4 times as expensive but are light years better. After having put this thing together, the last thing I wanted to do was spend more time taking it apart to replace bad parts.

Really needs better instructions or really any at all but I treated it like a puzzle and got almost more enjoyment out of it.

all parts accounted for and as specified. The finish is a bit rougher then I was expecting however that just makes them easier to screw together and have plastic components grip the metal frames. This is proving to be an advantage for low torque connections.

Excelente producto

I ordered this kit thinking it's going to take 2 weeks to receive but turns out it was only a few days.The kit was packaged quite well and the pictorial instructions were easy to follow.Great product.

No Instructions, no pictures to go by. Nothing. I wonder how it all fits together.???

Although, I just received this yesterday, two weeks ahead of schedule. I did need to contact Sain Smart for assembly directions: This link works and has pictures of parts in subassembly form. At least it helps.. now for all my servos to arriveThank you for your email.We are awfully sorry that we only have one assembly document for the item SainSmart 17DOF Biped Black Educational Robot Kit with Servo Bracket Ball Bearing.You are kindly suggested to download the documentation in the following link for reference.Amazon is deleting the link supplied by SainSmart for assembly"https://s3-ap-northeast-1.amazonaws.com/sain-amzn/20/20-011-111/20-011-111+Assembling+instruction.zip"[...]

This is a fantastic kit to build a biped robot from, you do however need to provide not only 17 MG-996R servos but also the servo horns that this uses (metal round ones) are not usually included with the servo's so you need 17 of those too. These cost between a pound and £2.50 each so shop around, other kits include these for only about £10 more.To run 17 servo's you are going to need lipo batteries and a big UBEC. I used a Turnigy 2.2 20-30C 2200mah lipo with a Turnigy 6v 8A UBEC (with a peak 15A load) and it works nicely, each of these will cost about £15 to £20. A servo controller board and a bluetooth serial link will complete the line up, or us arduino nano's (which I prefer) and a servo driver - I recomment the adafruit 16 channel one, the other servo can be controlled directly by the ardiuno, its only for the head so isn't that important). Total build (not including controller) is about £180 which is by far the cheapest way to get a biped robot. However this is not for beginners, and should not be attempted as your first foray into either electronics or robot design. The instructions to put this together are nothing but a series of poor photographs, and do not give much away (in fact I found some photo's of it ready built on the web and they were far more useful). My built robot is awesome, and I am now just writing the software to control it. One of the best projects I have done so far.

This kit arrives as per the picture but with NO instructions.The Product website is No use as it does not have instructions or even decent pics.It promised a tutorial if you created an account with them .. I did this only to find the Tutorial section empty..Gee thanks !!!After complaining I via Amazon I got some pictures showing different stages of assembly.These need interpretation to say the least but if you are thoughtful they are enough to build at least the legs which I've done so far.The Servo's require Hubs rather than horns and preferably metal ones since they will probably last longer.The screw fittings do actually fit the hub so I feel the previous reviewer may need to check this out.OK if you need a cheap model with reasonable parts ..no good unless you've done this stuff before or are some form of mind reader!!

No instructions if you wanted to build a biped !All drilled holes on every piece for servo horns do not mate with any horn I have seen.Waste of money

本体は太子お一人様強ですが完成させるまでに掛かる総額は、ロ＊＊ーナノと同じ位かそれ以上かもしれません、でもワクワク感は比較になりません従い、何を目的として購入するのか？何が付いていて、何を揃えたら良いか、良く考慮・計算してから購入しましょう多分道のりは長いと思います。購入して解ったこと、　・フレーム部品は写真通り　　　　　寸法精度・曲げ加工ほかとても良く出来ています。　・組立てのネジは参考組立写真と異なるので注意が必要です。　　　　　フレームの固定用　M3　長さが２種類あります。　　　　　組立参考写真集は皿ネジを多用していますが、付属は丸ネジが大半です。　　　　　サーボモータ固定　M4　一種類です。　・サーボホーン　が　別途必要　　　　 （ﾗｼﾞｺﾝﾕｰｻﾞｰは普通なのでしょうが、初心者の小生は　　　　　少し回り道をしました。ｻｰﾎﾞ付属のﾌﾟﾗｽﾁｯｸ製ﾎｰﾝは寸法が合いません）　　　　　ｻｰﾎﾞﾓｰﾀｰの指定をしているので、ｻｰﾎﾞﾎｰﾝの購入標記をするか又は　　　　　ｻｰﾎﾞﾎｰﾝは、最初から付けておいて欲しいです　　　　　小生は組立て写真とアマゾンの表示写真の違い　　　　　から購入手配をしました、ご存知の通りサーボメーカーにより　　　　　形状が異なるので、専用品をｻｰﾎﾞﾓｰﾀｰの数分（17）購入しました　　　　　（購入費用が別に￥5000位と2週間の配送日程）　・サーボモータ　及び電源は当然別途必要　　　　　MG996Rが１２個　MG995が５個　（購入小計　約　￥22000-）　　　　　電源は4.8～7V指定なので、　6.6Vﾊﾞｯﾃﾘｰにしました。（￥5000-：充電器含む）　・組立ては、解凍した組立て写真を良く見てから行うことをお奨めします　　　　　特に、左右勝手違いに注意して　　　　　教育用ですから失敗しても大丈夫！！後戻りできます。　　　　　分解して、また組み立てれば良いです。制御方法をどうするか？は最も「楽しい」悩みどころ！？　　　arduinoUNOのｾﾝｻｰｼｰﾙﾄﾞでは１２個までのｻｰﾎﾞが　　　MEGAのｾﾝｻｰｼｰﾙﾄﾞでは48個までのｻｰﾎﾞが駆動可能です。　　　小生は、arduino MEGA （互換）に　MEGA用ｾﾝｻｰｼｰﾙﾄﾞ　をつけて　　　すこしずつ動かして行く予定です。　　　ロボットの基本型「気を付け！」に常に戻って　各々の関節の角度をどうするか　　　を出発点として、あとは、途中から変えるときの角度の差分でしょうか？　　　各動きを分解写真の組立て＝ﾊﾟﾗﾊﾟﾗ漫画と同じく　17自由度を考慮して　　　17の配列に置き換える。それを組み合わせて命令し動かす。　　　いわゆる「ﾓｰｼｮﾝｱﾝｸﾞﾙ」配列集を作る必要があります。　　　追記：ネットにさりげなくﾛﾎﾞｯﾄの「ハンド」部品が表示されています。（自由度ﾌﾟﾗｽ４？）とゆうことで、完成まで、かなりの時間楽しめると今からワクワクしています。
