pib V5 roadmap and strategy
pib has three stable releases, V2/V2023, V3/2024, V4 and now it's time to enhance and innovate further with the V5 release.
Development Goals for V5
pib hardware enhancements
Minor improvements will be made to the existing pib model to refine its usability, aesthetics, and interactivity. Some goals include:
Hand redesign
Palm grasp friendly design
Screws instead of pins
3 Joints
Better grip (Old hand could grab a small bottle, new hand can grab a marker)
TPU skin grip
Stronger upper arm rotation
Upper arm rotation joint uses DS180SSG instead of DS3225
Direct driven wrist design
1 DOF wrist with MG996R for Edu
1 DOF wrist with STS3215 for Advanced
Central-Rotator
Teeth should be added to central rotator connectors just like in other joints to reduce possible wear (this will be added in v4.0.3)
Add a second metal-ring (M07) to the axial bearing to reduce friction. Just like in the pib #4S (suggestion from Scent)
Servo array improvements
Wire connector for servo arrays is improved to be less prone to breaking
Servo Array redesign/reposition to be easily maintainable in pib by making it vertical and accessible from lower dower
Tubes go all the way till the beginning of the motors
Minor improvements
Head enclosure to cover head opening
Rotating C74
Electronics
Switch shoulder vertical motor to 12v variant with double the torque
Lengthen B47 to access Relay and wiring better
Include ventilation holes for shoulder vertical motor in C61
Use 12v power supply with stepdowns
Software Ideas
Software is not released periodically with each version but here are the changes that are important to be in pib V5
Error software
Warnings at high current
Zero position at dangerously high current or shut down relay
Motor failed message when current is 32A
Demos menu in Cerebra for imitation script and similar
Pose editing
Move end effector in space with kinematics in cerebra with a virtual joy stick
