Job Description:

ROLE: Machinist

About role:
We are seeking engineers, technicians, and a machinist to help us complete construction
of, and demonstrate, the world’s most energy productive humanoid robot. RangerMAX
was brought to Plaksha University, in Chandigarh (Mohali) by Professor Andy Ruina
(ruina.org). The project is initially for 18 months and, with funding will go for at least
5 years. Eventually, the lab plans to expand to a space robotics center, developing robots
for exploration of the moon and mars. The team will only be about 9 people, each with
high level skills in at least one area, and each with abilities and energy to work across
job-description boundaries. Projects: Biped, quadruped, anti-gravity simulator, motor
Testing.
We need a machinist who understands precision. The actuator housings, bearing seats,
and transmission components in our robots require tolerances down to 0.02 mm and tight
concentricity specifications. Most fabrication is done through external manufacturing
partners, but we need someone in-house who can make jigs and fixtures, do emergency




repairs, inspect incoming parts, and talk to our manufacturers in their language about
what we need and why.
This role involves both making things yourself (manual lathe and mill, with CNC literacy)
and testing/managing the quality of things others make for us.

RESPONSIBILITIES:
· Operate manual lathe and milling machine for in-house work: jigs, fixtures, adapters, test couplings, one-off parts,
emergency repairs.
· Read and interpret engineering drawings with GD&T;: position tolerances, concentricity, runout, surface finish callouts.
· Inspect incoming parts from manufacturing partners: dimensional verification with calipers, micrometers, dial indicators, bore gauges, and surface plates.
· Communicate with external manufacturers: discuss drawings, explain tolerance requirements, negotiate manufacturing approaches, and verify first articles.
· Travel to manufacturing partner facilities as neede
