Lynxmotion T-Hex 4DOF Hexapod Robot Kit (Hardware Only)
Description
- Four DOF (degree of freedom) leg design for dynamic range motion
- Perfect for adding weapons for local robot competition
- Made with ultra-tough aluminum servo erector set brackets
- Includes brackets, frame and hardware for 4DoF T-hex hexapod
- Advanced development kit
The Lynxmotion T-Hex 4DOF Hexapod Robot Kit (Hardware Only) is made from ultra-tough high-quality aluminum servo erector set brackets. The T-Hex robot's body is Mech inspired. The use of offset brackets on the legs provides additional range of movement. The four DOF (degree of freedom) leg design means the robot can walk in any direction, just like the 3DOF version. But the 4th axis really expands the dynamic range of the robot's range of motion. The robot has been designed to use 24 HS-645 servos for the legs. This Mech inspired robot is perfect for adding weapons for your local robot competition.

Controlling the Robot
By offloading the servo pulse generation and sequence movement timing to the SSC-32 the microcontroller has plenty of power to do some really cool things. The Phoenix program allows the robot to walk with variable speed, in any direction (translation), or turn in place (rotation), or any combination of the two. The leg lift and ride height is adjustable as well as the gait walking speed. You can rotate the body in every axis. All of these are accessible from the controller.
Note that this is NOT a toy but rather an advanced legged development platform. Mechanical assembly instructions are provided. but the user must select electronics and program the robot. The Phoenix code (compatible with Lynxmotion's BotBoarduino microcontroller + SSC-32 servo controller + PS2 remote control) can be adapted for use with this robot at the discretion of the user.

I'm using this pack to build a custom walker. I didn't want the kit with servos, as I wanted to be able to experiment with servos of different speed/torque. I also did not want an 8-bit operating system. The aluminum is a good alloy, the assembly screws are coated steel (even with "Ford" hands, I managed to do all the assembly without stripping any). Be wary of the packaging, there are a LOT of bearings and itty-bitties that can be lost. I'm currently using Savox standard sized servos, which are just slightly taller than the Hitec's, have 3X the torque (at 4X the price), and they fit pretty good (the height of the gearbox on top of the servo is significant or the ball bearing fit into the servo bracket isn't quite right). I ended up putting the servo horns on the opposite side of the bracket and it worked fine. It's a little pricey, but this is all the aluminium and screws for a good 4DOF hexapod base. I've seen (slightly) better brackets, but the quality of the materials makes up for a minor bit of design awkwardness.
J'utilise ce pack pour créer un marcheur personnalisé. Je ne voulais pas du kit avec des servos, je voulais pouvoir expérimenter avec des servos de vitesses / couples différents. Je ne voulais pas non plus un système d'exploitation 8 bits. L’aluminium est un bon alliage, les vis d’assemblage sont en acier revêtu (même avec les aiguilles «Ford», j’ai réussi à faire tout l’assemblage sans en dénuder tout). Méfiez-vous de l'emballage, il y a BEAUCOUP de roulements et de morceaux qui peuvent être perdus J'utilise actuellement des servos standard Savox, qui sont juste un peu plus hauts que ceux de Hitec, j'ai un couple 3X (à 4 fois le prix), et ils me vont très bien le roulement à billes dans le support de servo n'est pas tout à fait correct). J'ai fini par mettre les cornes du servo de l'autre côté du support et cela a bien fonctionné. C'est un peu cher, mais c'est tout l'aluminium et les vis pour une bonne base hexapode 4DOF. J'ai vu (légèrement) de meilleurs supports, mais la qualité des matériaux compense un léger inconvénient en termes de conception.
