Spider rig

Venture Category: Robotics

Community: Sensorica

We have finished our collaboration with the original sponsor. Anyone can now take this venture further. Feel free to take on the role of animator.

Objectives

Design and prototype a planar cable parallel robot, able to move a load in 3D space with constant and small speed, close to equilibrium, and with real time feedback from the actual position of the end effector.

Description

Following in the footsteps of the HangPrinter project, our aim is to democratize (open source) cable robots.

The project stated on August 24th, 2018.

This project was financially sponsored until September 25th. We are looking for new sponsors.


Challenge

  • Produce a low-cost, open source cable robot prototype.

  • Use low-cost and readily available components, as much as possible open source

  • Produce a complete documentation for assembly and operations.


Applications

3D printing, smart agriculture, manufacturing (pick and place), ...

Governance

more on Governance page
VENTURES are COLLABORATIVE, TRANSPARENT (anyone has access to the information that they produce) and OPEN (anyone can participate). They only produce deliverables based on OPEN SOURCE technology. VENTURES have a CUSTODIAN that represents them legally and acts as a trust for their tangible assets. VENTURES can have multiple EXCHANGE FIRMS, which are commercial entities that move products and services developed by VENTURES on the MARKET. EXCHANGE FIRMS oblige themselves by contract with the CUSTODIAN to share PROFIT with all contributors to VENTURES, from which they commercialize PRODUCTS.

Can we extend the capabilities of FarmBot by replacing the CNC frame with a more versatile string hanging rig?

Can we improve the capabilities of the Hangprinter by rethinking its motion control system?
