Drag the green target. The solver finds a joint vector; a servo chases it at 125 Hz under real velocity, acceleration and jerk limits — so the arm lags, and catches up.

Robotics Engineering Intern
Led end-to-end design and delivery of a custom heavy-lift drone in a two-person team: 15 lb payload capacity, 20-minute flight time, under $5,000 to build.
- 01Carbon fibre frame, with trade-off analysis across propulsion, battery and propeller sizing against thrust-to-weight.
- 02Custom mounting mechanism for a refrigerated payload module — secure attachment, load distribution, vibration isolation.
- 03Full electrical integration: flight controller wiring, ESC configuration, power distribution.
- 04Component sourcing across India and China, cost against reliability.
Our bill of materialsunder $5,000Commercial platform$14,000Delivered the payload and endurance specification of a $14,000 commercial platform on a bill of materials under $5,000. Matched on payload and endurance.
Excludes our own labour, and the warranty, spares, support and service life the commercial price also buys.

New Product Development Intern
Designed a robot tending cell for automated bottle-cap tapping — a single arm serving two stations inside a fenced enclosure — and the camera-equipped end effector that went with it.
- 01Prototyped the tapping machine in SolidWorks: one set of tooling spanning Ø26–38 mm — 40 % of the commercial bottle-cap range.
- 02Automated fastener application with integrated torque sensing took 5 % out of the per-assembly manufacturing cost against the manual process.
- 03Designed a camera-equipped end effector for industrial robots, applicable across arc welding, spot welding, painting and pick-and-place.
- 04Calibrated 6-axis industrial robots on precision equipment — Tool Centre Point calibration, residual within ±0.1 mm over four approach directions.
- 05Field analysis at the Honda plant in Tapukara, Rajasthan.
