I placed on YouTube 3 videos of Biped, which I made of the Lynxmotion parts using Lynxmotion tutorials and a lot of great information found in this Forum.
The videos can be searched in YouTube by their titles, which start with:
“Biped Pete Jr. V1.0 Video”
(Sorry, the forum doesn’t allow me to include the web links yet.)
Wow! Excellent work! I really like the little guy. 8) Are the brains on board? What are you using for the voice? It’s very intelligible. Really nice work!
Here is some information about this Robot. I used only the Lynxmotion parts except the PS2 Controller, the sound board and the switch panel.
Hardware:
• Number of DOF’s: 14: 4 per leg, 2 per arm, 2 – in head (pan and tilt).
• Servos: 12 – HS-5645MG, 2 – HS-422 (head).
• Servo Controller: SSC-32 with Atmega168 and 512 bytes of EEPROM.
• Main Controller (“Brainâ€
Voice Extreme Module is based on RSC-300, which is, according to SENSORY’s application notes, a ROM-less version of the RSC-364. I bought it few years ago.
I placed on YouTube 5 videos, which demonstrate a program that controls my biped’s walk using IK like algorithm. Synchronously with robot’s control the program displays its movement on the screen. This simulation of walking can be done without the physical robot as well.
The goal of this project was to create an Inversed Kinematics algorithm and a Visual Basic program, which would calculate all servos’ rotation angles for the Lynxmotion Biped Pete Jr.’s forward walking. For the given robot’s dimensions, which can be entered on the project’s Setup screen, the program calculates all servos’ (joints’) rotation angles in each biped’s position for the following two parameters:
Distance between the feet.
Robot’s tilt: lift of the body’s in-air side over the on-ground side.
The Simulation screen allows:
• start and stop robot’s walking,
• test gait in either continuous or interrupt after each step or each position modes,
• control robot’s speed by changing time interval sent to the SSC-32 controller,
• in order to view simulated gait from different view angles the program has also capability to rotate coordinate system on the screen.
The videos can be searched in YouTube by their titles, which start with:
If there is some interest to this project I could add, with Lynxmotion permission, the algorithm’s description and the VB source code to the robot’s project page:
Here is a snapshot from the first video. Very impressive work Alex! Based on your last project I’m not surprised. Yes we are very interested in hosting the files on your project page! Please email them to [email protected] and we will take care of it right away. Thanks for posting!
